Welders operate manual/semi-automatic welding equipment to weld ferrous/non-ferrous metals following blueprints and welding process specifications. They may specialize in certain types of welding such as ship building, aerospace precision welding, and pipeline construction welding. They repair worn parts of metal by welding on extra layers.
Welding machine operators use previously set up welding machines such as spot, butt and seam resistance or gas and arc welding machines to fabricate and repair metal parts.
Brazing and soldering machine operators use previously set up brazing and soldering machines to bond metal parts and to fill holes, indentations and seams in metal articles with solder.
