Types of welding

2019-04-19 12:45:24

  Welding, the joining of two metal pieces seamlessly through the application of heat and pressure with a filter material, is at the heart of all metalwork.But in today’s world, not all types of welding are the same. In fact, there are several very different options today’s welders have when it comes to welding.

  GAS METAL ARC WELDING/METAL INERT GAS WELDING

  This is a type of welding that uses a wire attached to an electrode current to join two pieces of metal together. A shielded gas along the electrode heats up the two metals you are fusing. You would use this type of welding in industrial situations when fusing stainless steel or aluminum. Gas metal arc welding requires a direct current power source with constant voltage.

  TUNGSTEN INERT GAS WELDING/GAS TUNGSTEN ARC WELDING

  This is similar to the above except you are using a tungsten electrode which heats the base metal to create a molten puddle. Because of this, you can create an autogenous weld where you simply join the two pieces together with the molten base metal as your joining material. This is a more complex welding process that an expert welder would use when you need a seamless join with a superior finish.

  SHIELDED METAL ARC WELDING

  Sometimes just called arc welding, or occasionally “stick,” this is a very basic type of welding where the welder uses a stick with an electric current that creates an arc between the stick and the two metals you are joining. This is an effective method of welding steel or iron in construction, manufacturing, repair and other industrial applications.

  FLUX-CORED ARC WELDING

  Flux-cored arc welding was created as an alternative to shielded metal arc welding or metal inert gas welding. However, instead of shielded gas to heat the metal, flux-cored arc welding uses a tubular wire filled with flux. Flux-cored arc welding is quite easy to learn and implement. It’s also cost-effective, but it does not always produce as high-quality or attractive a weld as other methods. For that reason, it’s usually used in construction projects where speed and flexibility are a priority over aesthetics.
