B-9 B-9 LEARNING T O WELD PROCESS SELECTION By gaining knowledge of the differences between the two processes, you will be able to select the best process for the job you have at hand. In selecting a process, you should consider: For GMAW (MIG) Process 1. Is most of my welding performed on 16 gauge and lighter materials? 2. Can I afford the extra e[...]

B-10 B-10 LEARNING T O WELD FIGURE B.12 Penetration Unless a weld penetrates close to 100% of the metal thickness, a butt weld will be weaker than the material welded together. In the example shown in Figure B.13, the total weld is only half the thickness of the material thus the weld is only approximately half as strong as the metal. FIGURE B.13 F[...]

B-11 B-11 LEARNING T O WELD FIGURE B.16 Vertical-down Welding Refer to Figure B.17 Vertical-down welds are applied at a fast pace. These welds are therefore shallow and narrow and, as such, are excellent for sheet metal. Vertical-down welds may be applied to 5/32 ” (3.9 mm) and lighter material. Use stringer beads and tip the gun in the direction[...]

B-12 B-12 LEARNING T O WELD ARC RAYS can burn eyes and skin. When using an open arc process, it Is necessary to use correct eye, head and body protection. Protect yourself and others, read “ ARC RAYS can burn ” at the front of this manual. • The Correct Way To Strike An Arc • Be sure the work clamp makes good electrical contact to the work.[...]

Helpful Hints • For general welding, it is not necessary to weave the arc, neither forward or backward nor sideways. Weld along at a steady pace. You will find it easier. • When welding on thin plate, you will find that you will have to increase the welding speed, whereas when welding on heavy plate, it is necessary to go more slowly in order t[...]

B-16 B-16 LEARNING T O WELD • After you strike the arc, practice the correct electri- cal stickout. Learn to distinguish it by its sound. • When you are sure that you can hold the correct electrical stickout, with a smooth “ crackling ” arc, start moving. Look at the molten puddle constantly, • Run beads on a flat plate. Run them parallel[...]

B-17 B-17 LEARNING T O WELD Proper Gun Handling Most feeding problems are caused by improper han- dling of the gun cable or electrodes. • Do not kink or pull the gun around sharp corners • Keep the gun cable as straight as practical when welding. • Do not allow dolly wheels or trucks to run over the cables. • Keep the cable clean. • Inner[...]
