In TIG welding, you feed the filler rod into the molten puddle by hand. Your choice of filler rod is extremely important as the rod must correctly match the alloy of the material you will be welding. The thickness of the material you will be welding also determines the required diameter of the filler Guide for Aluminum Welding - Hobart BrothersAs a premium filler metal solution, Hobart .

Jun 01, 2010 · Hold the MIG gun at a 90-degree angle to each piece of metal when welding a butt joint to direct the heat and filler metal equally to each piece of material. Flat position. Butt weld (a 180-degree joint). Hold the gun at a 90-degree angle to the workpiece, directing the filler metal straight into the joint (but don't forget to include your travel angle of 5 to 15 degrees). Metal Fabrication and Welding (MFAB) < Johnson County MFAB 136 Gas Tungsten Arc Welding (GTAW) I* (3 Hours). Prerequisites :MFAB 124. Through classroom and/or lab/shop learning and assessment activities, students in this course will:explain the gas tungsten arc welding process (GTAW); demonstrate the safe and correct set up of the GTAW workstation; relate GTAW electrode and filler metal classifications with base metals and joint criteria;
Filler Metal Classification Filler Size Diameter mm (in) Current Amps Volts Wire Feed Speed mm/min (in/min) Travel thick:1.1T Max. (Except GTAW process). ASME IX, QW-403.9] T:Thickness of Test Plate or Pipe Wall in PQR (ASME Section IX, Table QW-451.1) We certify that the statements in this record are correct and that the test welds Recommendations for Welding T-1 Steels WELDING For submerged arc welding this would require the use of filler metals having an AWS classification of F11A6-ECM2-M2-H8. An example of this wire/flux combination is 880/LAC-M2 from Lincoln Electric. Other manufacturers also have wires and fluxes that provide the requirements of this classification.
Proven welding techniques that are procedurally correct and metallurgically sound involve consideration of the following factors:a. Characteristics of the alloy type b. Choice of filler material that the filler metal used in welding this grade create a weld deposit closely matching the base metal. Castings are welded in the solution Should I use 4043 or 5356 filler alloy? - ESABAs a basic description we can say that 4043 is an aluminum filler alloy with 5% silicon added and that 5356 is an aluminum filler alloy with 5% magnesium added. There are some misconceptions within the industry that you can successfully weld any aluminum base alloy with either 4043 or 5356 filler alloy.
Oct 28, 2008 · Although titanium has a reputation for being difficult to weld, it doesn't have to be problematic. Paying close attention to filler metal selection, cleanness, and use of the shielding gas are three steps to successful GTAW on titanium tube and pipe.
