Analyzes engineering data and welds experimental parts and assemblies to determine most effective welding processes, using various welding techniques and equipment: Analyzes engineering drawings and specifications to plan welding operations where procedural information is unavailable. Lays out parts and assemblies according to specifications. Develops templates and other work aids to hold and align parts. Determines type of welding to be used, such as metallic arc, inert gas, electrode, and oven treatment, applying knowledge of metals to be joined, contours and angles to be formed, and specified stress tolerances. Welds components in flat, vertical, or overhead positions, and adjusts amperage, voltage, and speed during joining to assure required weld deposit. Inspects grooves, angles, gap allowances, and related aspects of assembly to ensure conformance to specifications, using micrometer, caliper, and related precision measuring instruments. Observes hydrostatic, x ray, dimension tolerance, and other tests on welded surfaces to evaluate quality of weld and conformance to production requirements.
