Welders fuse metal parts together for various purposes.

What do Welders Do?

Welding, a process of joining together pieces of metal using heat, is an important component of construction, manufacturing, and other industries; welders are responsible for performing this work in many different contexts. They operate and at times maintain welding machines and must wear protective gear such as specialized masks. The most common type of welding involves using electrical currents to create heat, which melts and fuses metal parts to bond them together. However, there are many other different processes that welders can use, and the process a welder may select depends on the type of metal with which he or she is working and the context in which the work is performed. Welders may work in factories, in repair shops, on construction sites, or even underwater or in outer space.
