What are the types of welding processes?

There are many welding processes that apply to different jobs and work environments.
The most common welding processes are:
•,Coated electrode welding, more commonly known as arc welding or MMA
•,TIG welding, performed with gas arc with tungsten electrode
•,MIG and MAG welding, performed with gas arc with solid wire electrode
•,Resistance spot welding or spot welding
For more precise applications, there are more advanced techniques such as :
– Submerged arc welding with wire electrode (SAW)
– Plasma welding (PAW process) and plasma cutting (PAC process)
– Laser welding
– Resistance welding
Finally, Friction Stir Welding (FSW process) is an innovative technology patented in the early 90s. .
