Key Rules on Welding Angle, Direction, and Speed

Work angle: With wire welding, hold the gun at a 10 to 15 angle into the direction you are pushing the weld. With stick welding, maintain a 20° to 30° lead angle in the dragging direction. With a fillet (tee) weld, hold the rod or wire (regardless of weld process) at a 45° angle between the two pieces of metal.

What is the Purpose of Flux and Shield Gas in the …

The American Welding Society (AWS) classifies all flux filled, hollow-cored wire as, “Flux-Cored wire.” Therefore, the process of using flux-cored wire is called, Flux Cored Arc Welding (FCAW). Since two different types of FCAW wire are available, one needing shield gas, the other not, the defining acronym FCAW, can be additionally sub-egorized into FCAW-S and FCAW-G.
