Class Concept

Work in this class involves the operation of acetylene and electric arc welding equipment in order to fuse metal parts in situations where weld strength is a necessity, such as in the construction or repair of steam boilers and high pressure steam lines as well as various types of machinery and equipment. Work also involves the assembly and disassembly of the parts to be welded. Work assignments are received from a shop foreman with general instructions regarding the welding needed. Work is performed at the journey level in accordance with established shop and trade practices, but incumbent exercises considerable initiative in developing his own procedures and work methods.

Lays out, cuts, and fits material for welding. Joins metal pieces by applying the torch or electric arc to surfaces and melting the welding rod and flux into the joint. Burns or cuts through metal by melting and oxidizing with a hot flame and free oxygen. Examines parent metals and alloys in order to determine their strength and heating properties, and determines the amount of heat to be applied. Makes metal articles such as brackets, pipe hangers, braces, bolts, and repair parts for machinery, trucks, implements and equipment.
