3. List of construction trades - Wikipedia

   en.wikipedia.org/wiki/List_of_construction_trades

   Ironworker (or steel erector, often includes welder), erects or dismantles structural steel frames. Structural steel installation is usually crane-assisted. Workers rely on mobile, elevated platforms or scissor lifts. Ironworkers bolt the steelwork together using various tools, power tools and manual tools.

   Electron beam welding: 51 511: EBW Deep penetration, fast, high equipment cost Electroslag welding: 72: ESW Welds thick workpieces quickly, vertical position, steel only, continuous consumable electrode Heavy plate fabrication, construction, shipbuilding Flow welding (previously cast welding)

5. Welding - Wikipedia

   A related process, flux-cored arc welding (FCAW), uses similar equipment but uses wire consisting of a steel electrode surrounding a powder fill material. This cored wire is more expensive than the standard solid wire and can generate fumes and/or slag, but it permits even higher welding speed and greater metal penetration.

6. Metal fabrication - Wikipedia

   Workers welding in parking garage. Welding is the main focus of steel fabrication. [8] Formed and machined parts are assembled and tack-welded in place, then rechecked for accuracy. If multiple weldments have been ordered, a fixture may be used to locate parts for welding. A welder then finishes the work according to engineering drawings (for ...

7. Welding Procedure Specification - Wikipedia

   The AWS defines welding PQR as a record of welding variables used to produce an acceptable test weldment and the results of tests conducted on the weldment to qualify a Welding Procedure Specification. For steel construction (civil engineering structures) AWS D1.1 is a widely used standard.
