Job Summary:

　　This incumbent welds metal components together to fabricate or repair products, such as machine parts, plant equipment, mobile homes, motors and generators, according to layouts, blueprints or work orders, using brazing and a variety of arc and gas welding equipment.

　　This worker welds metal parts together, using both gas welding or brazing and any combination of arc welding processes, performs related tasks such as thermal cutting and grinding, repairs broken or cracked parts, fills holes and increases size of metal parts, positions and clamps together components of fabricated metal products preparatory to welding.

　　This worker may locate and repair cracks in industrial engine cylinder heads, using inspection equipment and gas torch, may perform repairs only and be required to pass employer performance tests or standard tests to meet certification standards of Governmental agencies or professional and technical associations.

　　Using accepted trade methods and a variety of manual welding processes, performs welding duties using electric, acetylene and/or inert gas shielded welding processes to weld various types of metals in various sizes, shapes, and thickness, including dissimilar metals.

　　Work is performed in a flat, vertical, horizontal, and overhead position.

　　Work processes include pre-heating, hazing, bead welding, tack welding, flame cutting, and heat treating.

　　Welders utilize shielded arc, metal inert gas (MIG), tungsten inert gas (TIG), and silver brazing oxygen/acetylene cutting plasma arc methods to fabricate and repair aluminum, steel and armor plate materials.

　　Welders must be capable of welding dissimilar metals such as copper to steel.

　　Must be able to read and interpret blueprints, sketches and diagrams.

　　Applies knowledge of welding standards and how various metals and alloys react to different welding standards and how various metals and alloys react to different welding processes and techniques.

　　Welds metal parts and structures that may vary in size, shape and thickness.

　　Welders must be able to laying out work, positioning and clamping templates; jigs and other guides to repair, modify, or fabricate metal items for all types of equipment including the repair of light and intricate made mechanical parts which must fit to close tolerance.

　　Welds stainless steel and aluminum, where complete penetration/fusion is required and where close tolerances must be met.

　　Adjusts machine to penetration/fusion is required and where close tolerances must be met.

　　Adjusts machine to permit welding materials of various thickness.

　　The work involves standing, walking, stooping, bending, kneeling and climbing. Work may be done in awkward and cramped quarters.

　　May handle objects weighing up to 50 pounds.

　　Constant exposure to dirt, grease, noise, odors, smoke and fumes with requirement for protective equipment such as: safety glasses, ear plugs, safety shoes, aprons, gloves, welding helmets, and goggles.

　　Work is usually performed on concrete floors or as required on or in equipment being repaired.

　　Subject to burns and eye injury when welding.

　　Danger from electric shock and falls from scaffolds or ladders, infrared or ultraviolet rays, fumes and gases.
