SECTION 8 − WELDING METHODS & TROUBLESHOOTING
A. Welding Methods
8-1. Shielded Metal Arc Welding (SMAW) Procedure
Tools Needed:
1
Workpiece
Make sure workpiece is clean before welding.
2
Work Clamp
Place as close to the weld as possible.
3
Electrode
A small diameter electrode requires less current than a large one.
Follow recommendations of electrode manufacturer when setting
weld amperage (see 8-2).
4
Insulated Electrode Holder

Arc Length
Arc length is the distance from the electrode to the workpiece. A
short arc with correct amperage will give a sharp, crackling sound.
Y Welding current starts as soon as electrode touches the
workpiece.
7
Slag
Use a chipping hammer and wire brush to remove slag. Remove
slag and check weld bead before making another weld pass.
