What do Arc Welding-Machine Operators do?

Sets up and operates arc welding machine that welds together parts of fabricated metal products, as specified by blueprints, layouts, welding procedures, and operating charts: Welds flat, cylindrical, or irregular parts that may be clamped, tack-welded, or otherwise positioned. May position weld line parallel to carriage. Turns cranks or pushes buttons to align electrode on welding head over weld joint to weld linear joints, or adjust length of radial arm to position electrode over weld joint when welding radial joints. Clamps cylindrical workpieces onto turning rolls under stationary head to weld circular joints. Threads specified electrode wire from reel through feed rolls and welding head. Turns welding head to set specified angle of electrode. May fill hopper with specified flux and direct nozzle or gravity feed over weld line, or adjust shielding gas or gas mixture flow rate. Turns knobs to set current, voltage, and slope, and synchronize feed of wire and flux with speed of welding action. May set limit switch which automatically stops machine at end of weld. Starts machine and observes meters and gauges, or observes welding action for compliance with procedures. Visually examines welds for adherence to specifications. May grind welded surfaces for penetrant test. Adjusts machine setup to vary size, location, and penetration of bead. May install track template to weld irregularly shaped seams. May make trial run before welding and record setup and operating data. May layout, fit, and tack workpieces together. May preheat workpiece, using hand torch or heating furnace. May reweld defective joints, using hand-welding equipment. May remove surplus slag, flux, and spatter, using brush, portable grinder, and hand scraper. May operate machine equipped with two or more heads. May be designated according to type of welding machine operated as Welding-Machine Operator, Electro-Gas; Welding-Machine Operator, Gas-Metal Arc; Welding-Machine Operator, Gas-Tungsten Arc; Welding-Machine Operator, Plasma Arc; Welding-Machine Operator, Submerged Arc.
