RESISTANCE WELDERS JOB DESCRIPTION
§ Sets up and operates resistance welding machines to join metal parts, according to blueprints, work orders, or oral instructions.
§ Operate machine controls to set air and hydraulic pressure, amperage, and joining time, according to specified type of metal, weld technique, and assembly
§ Aligns work pieces in clamping device or jig to maintain uniformity according to specifications and ensures that metal components are positioned correctly on machine worktable
§ Monitors the operation of welding machine which automatically releases electrodes from metal after welding cycle
§ Inspects finished work. Important variations include types of joints welded (seam, spot, butt) and types of materials welded (aluminum, steel).
§ Willing to operate other welding equipment or learn other welding processes.
SKILLS REQUIRED FOR RESISTANCE WELDING
§ Operate manual or semi-automatic welding equipment to fuse metal segments using processes such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), flux-cored arc welding (FCAW), plasma arc welding (PAW), shielded metal arc welding (SMAW), oxy-acetylene welding (OAW), resistance welding and submerged arc welding (SAW),
§ Read and interpret blueprints or welding process specifications
§ Operate previously set up welding machines such as spot, butt and seam resistance or gas and arc welding machines to fabricate or repair metal parts
§ Assist with the maintenance and repair of welding, brazing and soldering equipment
§ May adjust welding heads and tooling according to work specifications.
