B-10 SP 170-I 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. FIGU[...]

B-11 SP 170-I 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 [...]
