Question

Explain different types of welding?

Answer 1

Welding is the process that involves joining two pieces of metal together by applying heat. The process of welding can be performed in different methods. Some of the most popular types of welding are:

Shielded Metal Arc Welding

Gas Tungsten Arc Welding

Gas Metal Arc Welding

Flux Coded Arc Welding

1. Shielded Metal Arc Welding is the process that makes utilization of an electrode for carrying the current and providing the major amount of weld metal that composes the weld pool. This type of welding which is withal popularly referred to as stick welding makes utilization of a core wire which is coated with flux. When the arc is engendered, the temperature reaches an approximate value of 6500 degree Fahrenheit. The heat melts the electrode as well as the base metal. The welding procedure makes utilization of low-cost equipment that works well even on dirty and rusty metal.

2. Gas Tungsten Arc Welding

This type of welding employs the utilization of a tungsten electrode that does not get consumed in the welding process. The electrode heats the base metal in order to engender a weld pool. The process can withal at times utilize an external filler rod to engender the weld bead.

3. Gas Metal Arc Welding

The process of welding makes utilization of a solid wire electrode that is perpetually victualed. The welding process is very often performed by carbon dioxide or a commix of the carbon dioxide and argon. The advantage of this type of welding is that it reduces wastage owing to a high electrode efficiency. The welding process requires a very little weld cleanup and is one of the most facile procedures to learn.

4. Flux Coded Arc Welding

This type of welding process makes utilization of an electrode that consists of a tubular, flux-filled wire in lieu of the customary solid wire.
