Welders use accepted trade methods and a variety of manual welding processes, for example, several different gas torch processes, various electric are processes including inert gas shielded ones, or a number of both kinds of processes, to weld all types of commonly used metals and alloys of various sizes, shapes, and thicknesses, including dissimilar metals such as copper to steel. Welders also assure complete penetration when required as well as complete fusion of base and filler metals. They control the metals and the welding techniques to prevent distortion or burning of the metals, and to meet weld dimension, tolerance, strength, and other requirements. The welds are made in all positions including flat, horizontal, vertical, and overhead Job Description: + This covers the non-supervisory work of welding metals and alloys. The work requires knowledge of electric, gas, and other welding processes such as electron beam welding, and the skill to apply these processes in manufacturing, repairing, modifying, rebuilding, and assembling various types of metal and alloy parts, equipment, systems, and structures such as buildings, aircraft, and ships. + Welders determine the work to be done and the steps needed to accomplish it. + They plan and lay out the work from blueprints, sketches, drawings, specifications, and work orders. + They determine the welding techniques to use and select the proper materials such as the right size and type of welding electrodes or rods. + Welders apply a variety of manual welding processes to make more difficult welds, including welds in hard to reach places that must meet close tolerance, strength, and other requirements, for example, evenness of fit and smoothness of contour. + Final products are reviewed to see that welds are free from cracks, slag, or other defects, and meet specifications and accepted trade standards. + Welds are subject to radiographic, magnetic particle, dye penetrant, pressure inspection, and other tests. + The supervisor is called on for advice on unusual problems. Requirements: + Minimum of 3 years of combo welding experience in the field (Pipe welding Carbon and Stainless) + Welders may be involved in the gas welding torch processes such as oxy-acetylene, and other industrial gases. + The arc processes used (including inert gas-shielded ones) involve methods such as gas metal-arc, gas tungsten-arc, gas carbon-arc, plasma-arc, and atomic hydrogen welding. + Welders apply knowledge of welding standards and how various metals and alloys such as different kinds of steel, chrome, aluminum, cast iron, nickel, Monel, brass, copper, bronze, magnesium, beryllium, and titanium react to different welding processes and techniques. + They weld metal parts and structures that may vary in size, shape, and thickness from very thin (for example, .025 inches or less) to very thick (for example, armor plating), requiring multiple welding passes, and welding dissimilar metals such as copper to steel. + Welders also use greater skill to make welds that require complete penetration as well as complete fusion of base and filler metals even when welding in hard to reach places. As needed, Welders devise special jigs and fixtures to hold the parts to be welded. + They use techniques such as preheating, heat sinks, and stress relieving to maintain specified dimensions and to prevent distortion or burning of the parts being welded. + Incidental to the welding work, they also apply knowledge of several related trade procedures, for example, brazing, soldering, flame and arc-cutting, surface hardening, annealing, and metal spraying. + The work involves standing, walking, stooping, bending, kneeling, climbing, and crawling. Work may be done in awkward and cramped positions such as when welding in hard to reach places, welders frequently handle objects weighing from 9 to 23 kilograms (20 to 50) pounds and, occasionally, objects weighing in excess of 23 kilograms (50 pounds), in setting up work and equipment and in completing assignments. + The work is done indoors and outdoors, sometimes in bad weather, in areas that may vary from "clean rooms" to areas that are noisy, dirty, and smoky. Welding involves exposure to fumes, infrared and ultraviolet radiation, heat, flying sparks, the glare of torches and heated materials, the possibility of eye injury, electrical shock, burns, broken bones, and the chance of cuts when working with sharp objects.
