A welder is primarily responsible for joining metal parts together. In order to accomplish this task, the welder must apply heat to the metal pieces so they can be melted and fused together with a permanent bond. There are many different industries in which the skills of welders are needed. These include automobile manufacturing, shipbuilding, building construction, bridge construction, and more.
There are also several different types of welding processes that a welder can use. Although there are actually over 80 different types of welding processes, the most common is arc welding. Those that become skilled in arc welding generally learn TIG and MIG welding, which are the two most common forms of arc welding. TIG is generally used for aluminum and stainless steel applications and involves melting a rod to the pieces while MIG utilizes a continual spool of wire.
