Welding Processes

There are a number of welding processes that can be employed depending on the form and thickness of the material to be joined. However, most welding falls into two categories: arc welding and torch welding. If you’re interested in pursuing a welding career in arc welding, you should know that it requires a good eye for detail and steady hands. In this type of welding, the materials as well as filler material are melted together using an electrical arc. Common types of arc welding include the following:

  1. Gas metal arc welding
  2. Gas tungsten arc welding
  3. Plasma arc welding
  4. Shielded-metal arc welding
  5. Submerged arc welding

Torch welding, on the other hand, is a process that melts the working material and welding rod using an open flame. The most common application for torch welding is repair and maintenance work. The big advantage to this type of welding is that it allows the user to control the torch and rod at the same time, making it easier to be more precise. The most common type of torch welding is oxyacetylene welding.

Of course, there are many more welding methods than these, some of which are quite extreme. For instance, explosions, laser beams, and high-frequency vibrations can also be used to join metals together.
