GTAW, in my view, is the most difficult of all. The heat developed is the highest of all compared to other below-mentioned arc welding processes and the deposition rate is extremely low. The radioactive rays evolved out can damage our eyes more severely compared to other processes as well. Maintaining a sharp tungsten tip is mandatory for good quality weld. The torch is lightest of all but still challenging to use. Despite all the difficulties, the quality of weld joints produced is superior with minimum inclusions and it is the preferred process for highly critical applications (Ex- root welding of pressure vessel, nuclear and aerospace components). SMAW has the simplest of setup. Hence, it is easy to handle, can reach intricate corners. But since the electrode is consuming, both vertical and horizontal motion of the torch must be controlled manually to maintain the same arc length, which is difficult to master. On the other hand, in GMAW torches the electrode feed is taken care of by feed motors. Hence the vertical downward movement is not necessary and relatively simpler for unskilled welders. But, the heavier torch is comparatively difficult to handle especially if a welder worked with SMAW for a long time is made to work with GMAW. SAW is mostly mechanized and major complexity involved is with the setup that consumes the majority of the time. The inability to monitor the weld pool that is immersed under the powdered flux reduces the manual control over the process. Other solid-state welding processes like resistance welding, laser welding, induction welding, friction stir welding are mostly mechanized, monitored but their range of thickness is limited. And hence, they are mainly employed in automobile industries where sheet metals are predominantly used. In my view they are the easiest to handle once, process parameters are optimized. Ultrasonic welding, Explosive welding, Underwater welding, diffusion bonding do exist for decades but are highly limited to minimal applications and they come with their own set of problems for the welders.
