SP-135 PLUS B-9 B-9 LEARNING T O WELD The “ arc stream ” is seen in the middle of the picture. This is the electric arc created by the electric current flowing through the space between the end of the wire electrode and the base metal. The temperature of this arc is about 6000 ° F, which is more than enough to melt metal. The arc is very brigh[...]

B-10 SP-135 PLUS B-10 LEARNING T O WELD For GMAW (MIG) Process 1. Is most of my welding performed on 16 gauge and lighter materials? 2. Can I afford the extra expense, space, and lack of portability required for gas cylinders and gas sup- ply? 3. Do I require clean, finished-looking welds? If you have answered yes to all the above questions GMAW ma[...]

SP-135 PLUS B-11 B-11 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. F[...]

B-12 SP-135 PLUS B-12 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 t[...]
