KEY PROJECTS & ACCOMPLISHEMENTS FIELD REPAIR SUPERVISION

Mining equipment often requires regular maintenance and repair of various steel structures. Customers often request equipment representatives to help technically supervise critical repairs to insure they are done properly. The following example shows the typical field assignments Mr. Spadoni has performed in various locations such as the US, China, and Canada...

Oil Sands ShovelCanada

Dipper Field Repair-CanadaKEY PROJECTS & ACCOMPLISHEMENTS

When mining equipment breaks down it costs the mine millions of dollars. In this situation a large crack had developed on the underside of the dipper lug. If not repaired right away the crack would have most likely torn off the lug and caused further damage. The root cause of the cracking initiation was also traced back to the plant and the problem was solved before future orders would be effected.

MPT revealed cracking on bottom side of hoist lug.

Dipper

Crack located in 5” lug plate. Required thorough excavation and proper weld repair.

Truck Frame Field Repair Supervision-ChinaKEY PROJECTS & ACCOMPLISHEMENTS

This was a catastrophic failure where the Crawler Frame of this shovel had cracked and broken free from the truck frame. A large section of the truck frame was damaged and had to be replaced as shown. The new plate material was prepared, welded in-place using the proper welding parameters, and inspected using Liquid Penetrant.

Damaged Plate Section Removed.

KEY PROJECTS & ACCOMPLISHEMENTS

SHOP PROJECTSToday manufacturing facilities require flexible individuals who can work well with personnel on the floor as well as use their computer skills to report and present information on their projects to upper management. Mr. Spadoni has a strong hands on background as well as the necessary computer skills to fit in at both ends of the spectrum. Following are some examples of projects that Mr. Spadoni has been involved with over the past few years exercising those skills.

Gear Case Inspection & Rebuild Project

KEY PROJECTS & ACCOMPLISHEMENTS

Large gear cases are often used on mining equipment in order to move the massive buckets filled with material. At one point several gear cases began failing in service. In order to find the root cause of the failures each gear case had to be disassembled, the gears thoroughly inspected dimensionally and Non Destructively using Wet Magnetic Particle Inspection

Components were removed and inspected using Wet MPT. This revealed surface cracks in the tooth surface.

KEY PROJECTS & ACCOMPLISHEMENTS

Flanges were welded on by using GMAW .035” for the root pass and FCAW for the fill.

Welders worked simultaneously on each end while the pipe was rotated.

Pipe Fabrication Project

When a project was received to weld flanges on 300 pieces of pipe that were 60 feet long we stood up to the challenge.

A complete production line had to be made to move the pipe from one station to the next while insuring that each weld was X-Ray Quality.

After Welding the pipe had to be blasted, lined with rubber, and painted.

KEY PROJECTS & ACCOMPLISHEMENTS

One method is to grind the toes of the welds with a cone shaped stone grinder. The major problem with this method is that grinding is very unfriendly to the operator and can cause serious long term medical problems.

Fatigue Life Improvement of Welds

There are various ways to help improve the fatigue life of welds including Grinding, Peening, and Tig Dressing.

Some methods are more manufacturing friendly than others, however there was not enough specific data available on the which of those methods will be better or worse for improving the fatigue life of a weld.

Therefore a project was created to test several methods of improvement and choose the most shop friendly method that still produced a quality weld with enhanced fatigue life….Next Page

KEY PROJECTS & ACCOMPLISHEMENTS

Welded Tee Joint Coupon cut into 2” wide samples as shown.

Fatigue Life Improvement of Welds-Continued

Several methods of fatigue enhancement were tested by creating welded coupons for each method, cutting them into several samples, and then loading them cyclically in a tensile tester.

The testing took many hours to complete before a conclusion could be made. It was a good investment in that it save several hours of production time and medical costs.

KEY PROJECTS & ACCOMPLISHEMENTS

Steel cable wraps around the drum following these grooves.

Cable Rope Drum Rebuild Project

Large cylindrical drums are used to move large diameter cable on mining equipment. The constant movement causes a great wear in the rope grooves. Therefore when the drums are built the surface layer is heat treated to help retard the wear.Eventually the drums will have to be resurfaced with a hardened layer of material. Therefore a projects was started to come up with a welding electrode and procedure to perform this type of heat treatable weld buildup. Finally through the efforts of good electrode suppliers and engineers a heat treatable electrode was developed.

A type of centerline Cracking/Tearing constantly failed the test blocks.

Micro of Tear

Damien Avenue Bridge Project

KEY PROJECTS & ACCOMPLISHEMENTS

This large bridge was build for the Chicago area and uses two large arches as seen in the photo. The arches are made from 44” diameter sections of pipe which had to be welded together to meet AWS Bridge code requirements. The job was audited by city and customer inspectors.

Large diameter pipe segments welded together make up the arch of the bridge.

Weld Parameters Issue

KEY PROJECTS & ACCOMPLISHEMENTSWhen a historical amount of X-Rays were being rejected for large amounts of Tungsten inclusions, the root cause and solution had to be found.Dozens of variables presented themselves but with a close collaboration with the welders the source of the problems were found to be both technique and equipment related.Several X-Ray Quality welds on large Aluminum Heat Exchanger made to ASME Section VIII and IX.

Using sophisticated software the output wave of the machine could be analyzed to find that several voltage and current spikes were being experienced in older machines.
