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).

6 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.
