Welding is a fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. Welding is usually used on metals and thermoplastics but can also be used on wood. The completed welded joint may be referred to as a weldment. Some materials require the use of specific ...
WebbArc blow can cause a number of welding problems, including excessive spatter, incomplete fusion, porosity and lower quality. 15. Arc blow can be controlled or reduced by connecting the work lead to the end of the weld joint, and then welding away from the work lead. Webb4 juni 1998 · Arc plasma Welding Spectroscopy Chemical elements ABSTRACT The introduction of hydrogen into metals during welding is known to cause hydrogen assisted cracking and embrittlement in certain situations. It has been shown that the weld metal hydrogen content is directly related to hydrogen concentration in the weld arc plasma.
