EFFECT OF MIG WELDING INPUT PROCESS PARAMETERS

GMAW ( Gas Metal Arc Welding), is a welding process that is now widely used for welding a variety of materials, ferrous and non ferrous. The essential feature of the process is the small diameter electrode wire, which is fed continuously into the arc from a coil. As a result this process can produce quick and neat welds over a wide range of joints. Effect of MIG welding process parameters on microstructure Mar 22, 2019 · The existence of lower carbon percentage in this super alloy reduces precipitation of carbide during welding process in order to maintain resistance for corrosion. Inappropriate choice of welding process parameters and non-optimum heat input in welding can lead to cracking defects at weld zone/Heat Affected Zone for super alloys.

K Review of GTAW Welding ParametersWelding as a fabrication process is one of the vital production routes for most manufacturing industries. Several factors are involved in the choice of welding process for specific applications; notable among these are compositional range of the material to be welded, the thickness of the base materials and type of current. Most metals oxidize rapidly in their molten state, and therefore, the

Review on Techniques for On-Line Monitoring of Resistance

  • AbstractIntroductionby On-Line Welding Parameter MonitoringDiscussionsResistance spot welding has been widely used for joining sheet metals, especially in automotive and aerospace industries. However, since the formation of weld nugget is invisible in resistance spot welding, traditionally off-line destructive test is applied for inspection of the weld quality, which is costly and inefficient. Therefore, in recent years, a lot of efforts have been made in estimating or detecting the weld quality nondestructively by on-line welding parameter monitoring.
