Welds together metal components of products, as specified by layout, blueprints, diagram, work order, welding procedures, or oral instructions, using electric arc-welding equipment or any.
Obtains specified electrode and inserts electrode into portable holder or threads consumable electrode wire through portable welding gun.
Connects cables from welding unit to obtain amperage, voltage, slope, and pulse, as specified by WELDING ENGINEER or WELDING TECHNICIAN
Starts power supply to produce electric current.
Strikes (forms) arc which generates heat to melt and deposit metal from electrode to workpiece and join edges of the work piece.
Manually guides electrode or gun along weld line, maintaining length of arc and speed of movement to form specified depth of fusion and bead, as judged from color of metal, sound of weld, and size of molten puddle.
Welds in flat, horizontal, vertical, or overhead positions.
Examines weld for bead size and other specifications.
May manually apply filler rod to supply weld metal.
May clean or degrease weld joint or work piece, using wire brush, portable grinder.
May repair broken or cracked parts and fill holes.
May prepare broken parts for welding by grooving or scarfing surfaces.
May chip off excess weld, slag, and spatter, using hand scraper or power chipper.
May preheat a work piece, using a hand torch or heating furnace.
