There are more welding processes out there then I have fingers and toes! Let’s face it, if you pick up the classifieds, and look for welding jobs, there are going to be four types of welders that are in demand! That is the reason these four welding processes are the most commonly used:
Stick welding is one of the oldest welding processes used today. It is a very practical when it comes to being able to weld on the job site, in a shop, or even at home. The most common metals Stick welded are steel and stainless steel. Even though Stick welding is capable of welding many other metals these are the ones time has proven to be the most practical.
MIG welding is what is considered a semi-automatic welding process. Its main appeal is fast production and ease of use. MIG welding is typically used in factories, fabrication shops, and automotive manufacturing. The equipment can be complicated to set-up, but once things are in place, it is a breeze to operate. The most commonly MIG welded metals are steel, stainless steel, and aluminum.
TIG welding is known for the weld quality it produces. It is also the most difficult process to operate and requires a lot of skill. The main attraction of TIG welding is it can weld any known metal. More commonly this welding process is used in places that require extremely high quality welds or on exotic metals like titanium.
Flux cored arc welding it is not really another welding process. This process is nothing more than a different filler metal or wire used in a MIG welding machine. It is the fastest of the most common welding processes used today. For that reason it is typically used anyplace that needs massive amounts of welds like in shipyards. The metal that it welds best is steel. There are current developments for other alloys and metals but steel is the most widely welded metal with this process.
