MG 6316L - 16MG 6316 - 16

GENERAL CHARACTERISTICS:These alloys have a high molybdenum content to give them additional strength, even at high tem-peratures and to provide extra corrosion resistance to certain acids. The high quality, balancedchemistry of these electrodes gives them superior welding characteristics. They are designed with aspecial spray type arc transfer. This results in less heat input because a closer arc gap can bemaintained while welding. This also makes it an easier electrode to use in all positions. MG 6316 andMG 6316L have arc stabilizers in the coating that make them outstanding when used on AC ma-chines. The slag is very easy to remove - virtually self-lifting. The special coating ensures, dense,porosity free deposits.

APPLICATIONS:MG 6316-16 is designed to weld type 316 stainless steel. This group has molybdenum added toincrease its corrosion resistance and creep strength at elevated temperatures. Chemical plants,pulp and paper, and textile dyeing industries use this alloy because of its resistance to corrosionfrom sulfite liquor solutions. Also used in petroleum refinery equipment and phamaceutical equip-ment, as well as photographic equipment, food processing equipment and nuclear equipment. MG6316L-16 is used on 316L grades of stainless steel or where carbon content must be low, also forCF-3M, CF-8M castings.

SPECIAL MULTI-TEMPERATURENICKEL SILVER ALLOY FOR HIGHSTRENGTH JOINING & WEARRESISTANT BUILD-UPTORCH OR INDUCTION

GENERAL CHARACTERISTICS:Premium alloy available both bare and flux-coated for general maintenance repair with thetorch. At 1400°-1600°F the deposit has controlled fluidity which makes it ideal for surfacingand build-up of parts subjected to frictional wear. When the temperature is increased to1650°-1750°F the alloy becomes very thin flowing and will produce high strength joints withonly .001” to .003” clearance.

APPLICATIONS:1. Low temperature-overlaying and build-up of gear teeth, bearings, shafts, valve seats,wedge bars and steering knuckles.2. High temperature-for close fitting joints on broken drills, mill cutters, furniture andbicycle assemblies, attaching carbide cutting tips and many other applications requiringhigh strengths.This alloy is designed to build-up and join carbon steels, alloy steels, cast iron, and manynon-ferrous materials to themselves or multiple combinations.

STEELELECTRODES

(AWS E308-16) (AWS E308L-16)

GENERAL CHARACTERISTICS:MG stainless steel electrodes are balanced chemistry electrodes that have superior weldingcharacteristics. They are designed with a special spray type arc transfer that results in less heatinput because of the closer arc gap that can be maintained while welding. This also makes themeasier to use in all positions. The arc stabilizer used in the coating make them outstanding whenused on AC, particularly with limited duty cycle, low open circuit voltage AC machines. The slag isvirtually self-lifting. The special coating insures dense porosity free deposits.

APPLICATIONS:For fabricating and repair of types 201, 202, 204, 301, 304 and 308 stainless steel. Theseelectrodes are used where service conditions are not severe. Generally used on large fabricatedparts involving high volumes of welding, dairy and restaurant equipment and chemical tanks; also forCF-8, CF-3, CF-20 and HF castings.

PROCEDURE:For the TIG process, use DC straight polarity (electrode-) with a shielding gas of Argon orHelium. The parts should be clean and free of contaminates. No preheat is necessary. Onjoining thin sections, the joint should be square groove (a space between edges). Onthicknesses between 3/16” and 3/4”, use a single V joint. On thicker sections, use a doubleV joint. It is advisable to keep the weld puddle as small as possible to assure rapid solidifi-cation of deposit. When using MG-382 with oxy-acetylene, use a slightly oxidizing flame. Itis essential that MG-130 flux be used with the oxy-acetylene process. Welding can be donein all positions, but flat is preferred.

LOW TEMPERATURE SOLDERFOR ALUMINUMTO ITSELF OR OTHER METALS

ALL HEAT SOURCES

GENERAL CHARACTERISTICS:A special complex alloy system solder that has excellent wetting and flow characteristics onalmost all ferrous and non-ferrous metals. Since it has a “0” plastic range, its strengthremains relatively high even at service temperatures up to 350°F (175°C). This solder hasbetter corrosion resistance and higher strength than ordinary soft solders, but the bondingtemperature is much lower than the silver brazing alloys, therefore it is the ideal intermedi-ate alloy for joining.

APPLICATIONS:Aluminum radiators, aluminum tube to copper tube in refrigeration and air conditioningunits, sheet metal work, manufacture and repair of instruments, zinc base die casting andjoining of dissimilar metals. Also for use on anodized aluminum.

TECHNICAL DATA:Tensile Strength........................................................up to 22,000 psi (152 N/mm2)Working Temperature ...................................................................... 509°F (265°C)Color Match ....................................................................... very good on aluminumElectrical Conductivity .................................................................................... goodCorrosion Resistance ..................................................................................... goodDiameter (in)1/16

GENERAL CHARACTERISTICS:The deposits from this open arc wire contain a fine dispersion of ultra-hard titanium carbidesin a tough martensitic matrix. In turn, this provides excellent resistance to combined wear byabrasion, impact and/or pressure. MG 780W is a flux-cored wire that is specifically developedfor on-site maintenance and repair welding of thick, heavy components where faster welddeposition rates are desired.

APPLICATIONS:• Crusher Hammers• Crusher Rolls• Bucket Teeth and lips

TECHNICAL DATA:Typical Hardness:1st pass: … HRc 452nd pass: … HRc 553rd pass: … HRc 60Welding Parameters:DCEP (+)Range “A”: 350 375 amps @ 27-30 voltsRange “B”: 250 amps @ 25-27 volts*NOTE: Range “A” is for thick sections and high deposition rates. Range “B” is for thin sections, minimal dilution and low heat input.

PROCEDURE:Remove old welding deposits and worn metal with MG 570. Round of sharp corners. Preheatthe base material to proper temperatures, which should be determined based on thickness, aswell as carbon and alloy content. On hardening and self-hardening steels it may be necessaryto apply a buffer layer consisting of two passes of the MG 620W to act as a “cushion”. Oncethe arc is struck, work the arc in a circular weaving pattern to obtain a regular and compactdeposit. Maintain an arc length of approximately 1 ½”. Too long an arc can reduce the me-chanical properties of the deposit.
