... welded; weld quality in most metals is equal to or superior to that produced by gas tungsten arc welding (GTAW). Because the total kinetic energy of the electrons can be concentrated onto a small area on the workpiece, power densities as high as 10 8 W/cm 2 (10 7 W/in. 2 ) can be achieved. That is...

... tungsten arc welding (GTAW), and flux cored arc welding (FCAW). The SMAW process is very portable, used for structural applications where accessibility is limited, and historically has been very versatile. The GMAW process is gaining popularity because of an increasing supply of filler metal options and...
