(3 Cr)<br />
Continues instruction on operation of AC and DC power<br />
sources, welding polarities, heats and electrodes for use<br />
in joining various metal alloys by the arc welding process.<br />
Deals with running beads, butt, and fillet welds in<br />
all positions. Emphasizes safety procedures. Lecture 2<br />
hours. Laboratory 3-6 hours. Total 5-8 hours per week.<br />
WEL 126 Pipe Welding I<br />
(3-4 Cr)<br />
