JOB TITLE: WELDER

JOB CODE: 93410

DEFINITION: This is skilled work in cutting and joining metal components using welding equipment and related processes to repair, maintain, and fabricate parts, machinery, and structures.

An employee in this job performs routine and specialized welding repair and fabrication assignments. Work includes welding, brazing, soldering, cutting, tempering, and shaping ferrous and non-ferrous metals through the operation of acetylene, arc, tungsten inert gas (TIG) or metal inert gas (MIG) welding, and related shop equipment. Work involves laying out equipment and materials and determining work processes to fabricate parts and equipment; cutting, shaping, welding, and repairing metal structures or parts for a wide range of applications; and assigning and demonstrating welding related tasks to other trades and maintenance employees. Work is performed independently and checked in progress and upon completion for adherence to guidelines and quality and timeliness standards.

• Measures, lays out, and assembles components, materials, and equipment in preparation for welding.

• Fabricates parts and equipment through cutting, shaping, grinding, and welding materials and tests their functionality throughout the fabrication process.

• Welds cracked and broken parts made of cast iron, aluminum, steel, or other metals for motor vehicles, including trucks, snowplows, concrete mixers, cranes, graders, and other highway automotive maintenance and construction machinery.

• Cuts and welds steel components in bridge structures, including the replacement of broken or weakened parts, and welds stiffener angles, plates, and steel forms for concrete.

• Performs structural bridge repairs, such as removing and replacing welds and rivets with high strength bolts, removing projecting steel and caulking seams, and repairing and straightening broken or bent bridge members and grated bridge decks.

• Performs cutting and welding operations on plumbing, steam, oil, gas, and related piping systems.

• Lays out, cuts, fabricates, and repairs a wide variety of parts, equipment, and fixtures, such as tables, racks, tools, appliances, road signage, and fencing structures.

• Estimates time and material costs for repairs.

• Demonstrates and provides instruction to other trades and maintenance persons on welding related tasks.

• Complies with safety regulations and standards for work assignments, including wearing personal protective equipment.

• An employee in this job participates in the performance of other trades’ tasks consistent with operational and organization requirements.
