Have you ever considered where else you

might find all the products and services fea-tured at the FABTECH show? The simpleanswer is nowhere. Set for November1113 at the Georgia World Congress Cen-ter in Atlanta, FABTECH has developed intoa truly amazing focal point for everythingabout metalworking, including a weldingpresence that amounts to well over a thirdof the total show space. This yearsFABTECH is the second-largest in the ten-year period since the AWS Welding Showmerged with it, and the welding/cuttingspace sold is currently 48% greater than it

was the last time it was in Atlanta, in 2010.We expect some 27,000 attendees on handto view the products of 1400 exhibitingcompanies that will occupy more than550,000 sq ft of floor space.

In addition, there will be more than 100educational sessions to help you make themost of the broad array of metalworkingtechnology on display. AWS-sponsored ses-sions include programs on best practicesand new commercial developments in weld-ing and thermal spray, the Professional Pro-gram focusing on the latest in weldingresearch, the RWMA Resistance WeldingSchool, and more. Our show partners willoffer sessions on cutting, finishing, formingand fabricating, job shop solutions, automa-tion and robotics, stamping, and tube andpipe. A live demonstration area in Hall Awill include a special thermal spray demo,the AWS U.S. Invitational Weld Trials, and arobotic arc welding competition. FABTECHIndustry Night at the new College FootballHall of Fame will take place Wednesday,Nov. 12, at 5:30 p.m. Keynote speakers will

include luminaries from Walmart andGoogle, and ex-Pittsburgh SteelersSuperbowl Champion halfback Rocky Bleier. Whats the reason for the unprecedentedsuccess of FABTECH? The many reasons in-clude the continuing economic recovery, thestrong metal manufacturing and construc-tion markets in the Southeast (andelsewhere), the wide package of exhibitorsin one show, and continually growing inter-national interest. Although not as strong aswe would like, the economy is definitelygrowing, with the number of jobs

increasing. At the same time, U.S. manufac-turing is growing apace. Its an ideal

environment for both show exhibitors and

attendees, a situation that will definitelybenefit all parties involved. The importance of product exhibitions,generally, is not limited to the UnitedStates. Over recent years, we have seen sig-nificant and sustained growth in our annual

AWS Weldmex show in Mexico, held inalliance with FABTECH Mexico and Metal-form Mexico. We have also seen stronginterest in our FABTECH Canada exhibitionand the other shows in which we participatein Brazil, Germany, Japan, China, India, andmany other locations. The point here is that

it is abundantly clear, and particularly in arecovering economy, that face-to-face showsstill have a great relevance. The continuing success of the strongestshows, like FABTECH, is easy tounderstand. It results from a combinationof creating a showplace for the latesttechnology, plus an environment where po-tential buyers can view and watchdemonstrations of the latest equipment re-lated to their manufacturing and construc-tion operations. Combine this withtechnology-related education offeringsand you have an unbeatable, cant missmix of everything the consumer needs toknow. Of course, as show planners, we haventaccomplished all this ourselves. AWS greatlyvalues the skill and devotion demonstratedby its FABTECH partners: SME, the Fabrica-tors and Manufacturers Association, Inter-national (FMA), the Precision Metalforming

Association (PMA), and the ChemicalCoaters Association International (CCAI).

AWS and all of its partner associations con-

tinually strive to bring a more comprehen-sive and valuable show to both theexhibitors and all of the attendees, who aremutually dependent on each other toproduce a great exhibition.

Come join us this year at the FABTECHshow in Atlanta. We promise we will make itworthwhile for you from a businessstandpoint, as well as thoroughlyinteresting and enjoyable. For moreinformation on FABTECH, please visit ourwebsite at www.aws.org. This issue of theWelding Journal also features a comprehen-

sive preview of FABTECH 2014. We lookforward to seeing you there.

Manufacturing Universities Bill Introduced

The bipartisan Manufacturing Universities Act of 2014has been introduced in the U.S. Senate. This legislationwould establish a program within the Commerce Depart-ments National Institute of Standards and Technology(NIST) charged with designating 25 schools as Manufactur-

ing Universities. Designated schools would receive $5 mil-lion per year for four years to meet specific goals, includingfocusing engineering programs on manufacturing, buildingnew partnerships with manufacturing firms, growing train-ing opportunities, and fostering manufacturing entrepre-neurship. The program would be overseen by the director ofNIST, in coordination with the secretaries of Defense andEnergy, and the director of the National Science Foundation,among others. The intent is to provide incentives to betteralign educational offerings with the needs of modern manu-facturers. The incentives would be used to revamp theuniversities engineering programs to focus on manufactur-ing engineering and curricula specifically related to targeted

industries.

OSHA Updates Proposed PublicRecordkeeping Regulation

In late 2013, the Occupational Safety and Health Admin-istration (OSHA) proposed to expand its annual injury andillness reporting requirements by mandating that employerssubmit their reports on workplace injuries and illnesses toOSHA electronically. This information would then be includ-ed in a searchable online database. This represented a signif-icant change in the law, since presently employer-specificdata are not readily available to the public or even to em-ployees of a particular firm. This latter approach is believedto encourage accurate reporting of injuries and illnesses. Infact, OSHA is now concerned that these new proposed regu-lations may cause employers to underreport injuries and ill-nesses due to the increased visibility.

Therefore, OSHA has now proposed to expand the pro-posed rule by: requiring that employers inform their employees oftheir right to report injuries and illnesses; requiring that any injury and illness reporting require-

ments established by the employer be reasonable and notunduly burdensome; prohibiting employers from taking adverse actionagainst employees for reporting injuries and illnesses. These new requirements were published in the FederalRegister on August 14.

Export Control Reform Efforts Continue

The Departments of State and Commerce have publishedadditional regulations to continue efforts to streamline U.S.

export controls on certain military items by shifting less-sensitive equipment, parts, and components from U.S. Mu-nitions List to the less-sensitive Commerce Control List. These steps are part of the federal Export Control Re-form Initiative which is designed to enhance competitive-ness by overhauling the Cold War-era system of regulationsdesigned in part to update Cold War-era regulation of ex-

ports of controlled technologies. With these latest regula-tions, 15 of the 21 categories on the Munitions List havebeen successfully revised under the initiative. Work contin-ues on the remaining categories and other efforts to mod-ernize and harmonize the export control regulations.

Bill Introduced to Enhance Buy AmericaPolicy in Infrastructure Projects

The Invest in American Jobs Act, introduced in the U.S.Senate, is intended to improve Buy America preferences for

federal infrastructure programs. Specifically, this legislationwould improve Buy America preferences for federal highway,public transportation, rail grants, rail loans, Amtrak, andthe Federal Aviation Administration to maximize the use ofdomestic steel, iron, and manufactured goods in infrastruc-ture projects;

prevent segmentation of projects to circumvent BuyAmerica standards; apply enhanced provisions to projects sponsored by se-lect agencies, including Department of Transportation, theEconomic Development Administration, and the FederalEmergency Management Agency.

Available Federal R&D Data Expanded

A federal government website providing access to govern-ment information, www.data.gov, has been expanded to in-clude data on more than 700 Federal R&D facilities that maybe utilized to research, prototype, and test new technologiesin manufacturing and other industries. These facilities, op-erated by agencies including DOE, NASA, and NIH, repre-sent more than $5 billion dollars of taxpayer investment.Further expansion in the future is expected to include more

comprehensive data on other R&D assets, including federal-ly funded intellectual property.

Community College Sign 15-Year

Contract Extension

During a recent ceremony celebrating the 25-year part-nership between the United Association of Plumbers, Pipe-fitters, Sprinklerfitters, Welders, and HVACR Technicians(UA) and Washtenaw Community College (WCC), Ann Ar-bor, Mich., the parties signed a 15-year contract extension.

Attendees included UA General President William P. Hite,UA Director of Training Chris Haslinger, and WCC PresidentRose Bellanca. We have asked everyone to join us as we celebrate thesigning of our new agreement with WCCan agreementthat will allow our annual Instructor Training Program tocontinue here for the next 15 years, Haslinger said.

Every summer, instructors from across North America aswell as Australia come to the college to pursue certificationas instructors of UA apprentices and journeymen. The pro-gram benefits the Ann Arbor and Ypsilanti metro area bybringing revenue into the community. The UA maintains a full-time, year-round presence atWCC with full-time staff through its Great Lakes RegionalTraining Center. Members of its local unions from all acrossthe United States come there for training throughout theyear. This facility includes classroom and auditorium spacealong with hands-on labs and workshops. We are also here to celebrate the installation of a newmicroturbine project done jointly between our two organiza-

tions, Haslinger said at the event. GEM Energy, Walbrige, Ohio, recently designed and builtthe colleges first combined cooling, heating, and power sys-tem, plus donated another microturbine to train future en-ergy professionals at the Great Lakes facility. In addition,the company donated a Capstone C30 microturbine for theUAs training program at the college. Our partnership with Washtenaw Community College

Two STEM Education Efforts Announced

Lockheed Martin has donated $200,000 to Project Lead

the Way for implementing its science, technology, engineer-ing, and math (STEM) curriculum in all of the 26 elemen-tary schools in Alabamas Huntsville City School System.The grant makes Huntsville City Schools the largest schooldistrict in Alabama that has implemented this project in allof its elementary, middle, and high schools. In addition, more than 52 elementary school teachers inthe 26 elementary schools attended this projects profes-sional development training earlier this summer.

The first phase of Praxair, Inc.s Skills Pipeline programwill provide more than $300,000 to train 100 new weldersin an accelerated one-year curriculum in Louisiana. Funded by Praxairs Global Giving Program, and conduct-ed in cooperation with the Louisiana Community and Tech-nical College System, it will be offered through the BatonRouge, Delgado, and SOWELA Technical Community Col-leges. The program also provides funding for new instruc-torships and professional development opportunities for ex-isting welders.

Eastern Florida State College and NASAPartner for Welding Training

Eastern Florida State College (EFSC), Cocoa, Fla., andNASA Rocket U have partnered to provide Kennedy SpaceCenter engineers with a one-week comprehensive weldingtechnology training workshop. Ken Cox, associate professor of welding technology at thecollege, and Tom Merry, welding technology lab specialist,guided the students. Instruction included basic weldingtechniques; metallurgy fundamentals; shielded metal arc,gas tungsten arc, and gas metal arc welding applications;plus grinding functions. Rocket U was developed to help civil service and contrac-tor engineers expand their skill set in flight systems engi-neering and learn to better manage design programs. Theinsight into welding techniques allows engineers to commu-nicate more effectively with front-line welders. To date, EFSC Corporate Services and NASA Rocket Uhave facilitated three workshops covering classroom theory

and hands-on lab exercises for more than 45 professionals.The most recent session took place this summer, and they

hope to conduct future sessions.

North American Robotics MarketPosts Its Best Quarter

The North American robotics industry is off to its fasteststart ever in 2014, according to new statistics from the Ro-botic Industries Association (RIA), Ann Arbor, Mich. A record 14,135 robots, valued at $788 million, were or-

dered from North American robotics companies in the firsthalf of 2014. This represents an increase of 30% in unitsand 16% in revenue vs. the same period in 2013. The second quarter of 2014 was also the main driver ofthe markets record first half with 8197 robots valued at$450 million sold to North American customers. Since 2010, the robotics market in North America hasgrown an average of 26% per year. Simultaneously, the U.S.unemployment rate has fallen. Manufacturing jobs are nowreturning to the United States because of automation as well. While we often hear that robots are job killers, just theopposite is true, said Jeff Burnstein, president of RIA. Ro-bots save and create jobs.

Arc Plasma ResearchGarners Interest

This letter is in reference to the paper pub-

lished in the Welding Research Supplement

titled Separation of Arc Plasma and Cur-

rent in Electrical Arc An Initial Study, by

S. J. Chen, F. Jiang, Y. S. Lu, and Y. M. Zhang

in the Welding JournalsJuly 2014 maga-

zine (pages 253-s to 261-s).

I enjoyed reading this interestingand well-written article. It remindedme of work that was published in theWelding Journal and Welding Handbookback in the 1960s. The Welding Handbook, Chapter 53,Plasma Welding, Fifth Edition, page53.3, Fig. 53.1, clearly shows a non-transferred arc with separated arcplasma. The Sixth Edition of the hand-

book, Chapter 54, plasma arc welding,Fig. 54.4, shows a redrawn version ofthat Fig. 53.1. The redrawn figure stillshows a separated arc plasma. In the Welding Handbook, SeventhEdition, Vol. 2, Chapter 9, Fig. 9.4, theoriginal Fig. 53.1 was once again re-drawn. This time it was incorrectly re-

drawn and has been incorrect eversince. It shows the plasma portion ofthe system originating from the face

of the constricting nozzle instead offrom the electrode as in the originalFig. 53.1. This error should be cor-rected in the next Welding Handbookedition. The 1966 Welding Journal, Vol. 45,No. 11, pages 899908, by E. F. Gor-man, G. M. Skinner, and D. M. Yenni,

Plasma Needle Arc for Very Low Cur-rent Work, shows a correctly drawnstylized version of the same Fig. 53.1.

An article reprint by Linde clearlyshows a nontransferred separatedplasma see Fig. 1. Perhaps the authors of this excellent2014 article will find my commentaryhelpful in their future investigations.

A: Most brazing shops will occasional-ly be given rush jobs by their good cus-tomers and they do the best they canto comply; however, no brazer wants torisk losing a good customer by deliver-ing a poor-quality product. Lets suppose your vacuum brazingfurnace has just completed a series ofcycles that has left it contaminated.You were preparing to take the furnace

out of service for the next day or twofor maintenance including hand clean-ing, vacuuming, a high-temperatureburn-out cycle, etc, then a customershows up with a hot job that must bedone right away.

The customers assembly consists ofsome components made from 316L

stainless steel and others from atitanium alloy. These base met-als should be brazed in a thor-oughly clean and leak-tight fur-nace. What to do? Should you attempt to brazethe assembly in the dirty furnace

and risk an unsatisfactory brazeor just tell the customer you can-not do the rush job that day? Ipropose you enclose the assem-bly inside of a protective boxbefore placing it into the dirtyfurnace to ensure it will brazewell. Boxing an assembly prior tothe brazing run is a simple tech-nique that more shops shoulduse. Heres how to do it. Prior tobrazing, place the parts inside of a foil

box that is easily constructed by handspecifically for those parts. The foil boxshields the parts so they effectivelybraze inside their own pristine mini-furnace chamber. The foil box is usual-ly used only once, for a particular as-sembly for one furnace run. In my brazing shops, we kept rolls

of titanium foil and stainless foil onhand just for this purpose. The titani-

um foil may be either pure titaniumor a titanium alloy both types workwell. Similarly, the stainless steel foilmay be made from any one of anumber of different alloys. A regulargrade stainless steel foil works well.Using a low-carbon L-grade foil is notnecessary.

Q: What should we do when acustomer has a critical hot jobthat he wants brazed immediatelyand cannot wait for us to properlyclean the furnace and run the nec-essary leak checks? How can wemake a good braze when the fur-nace isnt ready?

When a customer gave us a verysensitive part that needed to be brazedright away, we did not delay brazingthat component until after the furnacewas cleaned. Instead, we placed the

component on some thin, clean alumi-na-ceramic sheet, which we thenplaced on top of some thin titanium orstainless steel foil. We then cut someshort slits in the foil to allow the foil tobe folded up to form a box around thecomponent taking care the compo-nent did not touch any of the foil. Fig-

ure 1 illustrates how this isdone.

Once two walls are fold-ed up, then the side wallscan be folded up into placeand the extra foil lengthfolded around the box toensure there are no openseams to the outside.

Everything is merely bentover, crimped, etc., usingpliers, metal shears, andother standard tools, sothat the box can be madequickly and easily by handright there in the shop.

The walls of the boxformed in this manner

should be tall enough so that the sidesof the box are higher than the top ofthe part to be brazed. Then, take an-other piece of the metal foil to make a

loosely fitting cover which is simplylaid on top of the box. Fold the edgesof the cover down so that there is ab-solutely no line-of-sight into the box.Figure 2 illustrates how this is done.Note: use thinner foils to make theseboxes, they are much easier to workwith. Keep the foils clean and stored

where they will stay clean and not oxi-dize. Always handle the foils with cleangloves and use clean tools to constructthe box and for placing the compo-nents inside it.

During the brazing cycle, the out-side of the box serves as a getter. Itcatches the outgas products in the larg-er furnace chamber atmosphere that

would normally condense onto or coatthe parts being brazed. But the foil boxcan quite effectively prevent those con-taminants from reaching the assemblyprotected inside. When the cycle isover and the box is removed from thefurnace, the outside of the box may ap-pear very dark and discolored. Howev-er, when the lid is carefully removed,the components inside the box shouldbe pristine clean and nicely brazed.
