The MeltView Dart-A is designed for remote, up close monitoring of 'dirty' welding processes such as gas metal arc welding (GMAW) that generate high amounts of spatter and metal vapour and are difficult or impossible for humans to access.
00 Hardcover TS227 The textbook begins with an introduction to the welding process and the role of welding in industry, then covers oxyacetylene welding, shielded metal arc welding, gas tungsten arc welding, gas metal arc welding, other welding and joining processes, weld evaluation and testing, and welding technology.
What's covered: Courses include basic plate and sheet metal, pipe welding, plasma cutting and gouging, oxyfuel process, alloy theory and applications, hardening, gas tungsten arc welding, gas metal arc welding/semi-automatic, flux-cored arc welding/semiautomatic, comprehensive program, advanced pipe, advanced submerged arc welding, and maintenance welding.
While the equipment needed to install a C3 magnetic pulse welding station is significantly more than gas metal arc welding, the process does not require filler materials or gas emission removal systems.
00 Hardcover TS227 Mandal works from his experience teaching courses on specialty welding, particularly that appropriate to shipbuilding, such as sheet metal arc welding, gas metal arc welding, gas tungsten arc welding, submerged arc welding and electro-slag along with single side and multi-electrode welding techniques.
Under modeling, there are papers on simulation of resistance welding, simulation of gas metal arc welding, weld shape and distortion modeling, solidification/weld composition modeling, general modeling and welding documentation.
