Fabricator Verify conformance of workpieces to specifications, using squares, rulers, and measuring tapes. Align and fit parts according to specifications, using jacks, turnbuckles, wedges, drift pins, pry bars, and hammers. Position, align, fit, and weld parts to form complete units or subunits, following blueprints and layout specifications, and using jigs, welding torches, and hand tools. Study engineering drawings and blueprints to determine materials requirements and task sequences. Set up and operate fabricating machines. Lay out and examine metal stock or workpieces to be processed to ensure that specifications are met. Tack-weld fitted parts together. Mark reference points onto floors or face blocks and transpose them to workpieces, using measuring devices, squares, chalk, and soapstone. Set up face blocks, jigs, and fixtures. Position or tighten braces, jacks, clamps, ropes, or bolt straps, or bolt parts in position for welding or riveting. Locate and mark workpiece bending and cutting lines, allowing for stock thickness, machine and welding shrinkage, and other component warped or bent parts, using sledges, hand torches, straightening presses, or bulldozers. Smooth workpiece edges and fix taps, tubes, and valves. Preheat workpieces to make them malleable, using hand torches or furnaces. Wash and cut with a torch
