Welder III

Summary: Welds together metal components of products such as drilling rigs, pipelines, pre-fabricated risers, vehicles, and heavy equipment using Shield Metal Arc Welding (SMAW), Gas Tungsten Arc Welding (GTAW), Gas Metal Arc Welding (GMAW), and oxy-acetylene welding. Gathers dimensions and lays them out on structural steel/high-pressure piping. Rolls, offsets, miters, and calculates to produce pre-fabricated finished goods. Fabricates/installations of conductor, Braiden-head, casing cut-offs, and plug and abandon.

Provides bill of materials/ISO for installation of compressors/pig launchers.

Essential Duties and Responsibilities include the following. Other duties may be assigned.

Welding Preparation: Obtains specified electrode based on criteria of raw goods being welded; inserts electrode into rod holder or feeds wire consumable through welding gun. Attaches ground clamp from welding machine to work piece, dials in adequate amperage, voltage, slope, and pulse to known standards. Starts engine-driven welding machine/electric welding machine to produce desired amps. Scratch starts arc to generate heat to produce a molten puddle, depositing filler metal from electrode to work piece;

joins edges of work piece. Preheats work piece with hand torch or heating furnace where applicable. Positions and clamps work pieces together or assembles them in jig or fixture. Tacks/welds assemblies together.

Welding: Manually guides electrode or gun along beveled or fillet edge, maintaining length of arc and speed to form specified depth of fusion, width, and convexity of weld on welded fixture, visually judged by color of base metal, sound of weld, and size of molten puddle. Welds in flat, horizontal, vertical, overhead on plate; 6G on 2-inch pipe and a butt and branch on 12-inch pipe.

Post Welding Duties: Cleans slag from weld joint. Visually examines weld for bead size, bead crown convex/concave, porosity, and undercut according to AWS, ASME, API 1104 welding specifications. Repairs out of code equipment/raw goods, such as broken or cracked parts, and fills cavity. Prepares parts for non-destructive testing (NDT); chips off excess weld, slag, and spatter.
