Essential Welding Processes

Posted on

Welding is described as the joining of two different metallic parts through the use of heat. This can be done with tools such as an electric arc or a blowtorch. The two metallic parts can be fused together through hammering to ensure the joint is strong enough to withstand any kind of external force. When welding for the very first time, one can be pretty intimidated by the bevvy of tools and the nature of the task. However, after learning some few crucial processes, you can comfortably pick out the best technique to use in various day to day welding challenges. Just like driving a car, welding requires a lot of practice and work to be entirely confident. Below is an analysis of the different processes you will find crucial during welding.

  1. Shield Metal Arc Welding – This process can simply be regarded to as arc welding. It is the most commonly used approach in the field today. The name arc emanates from the fact that the welding stick forms an electric arc between the metals to be joined with the use of an electrical current. This sort of welding can be used in construction, manufacturing or even repair works. It is also widely used in industrial fabrication as well as the creation of steel structures.
  2. Flux-Cored Arc Welding – This approach was developed to work as an alternative to shield welding. The main difference between this and the rest is that it employs a specialised tubular wire filled with flux. One of the advantages of this welding process is that it is simple to learn and quite cheap to execute. However, the results are not as aesthetically appealing as those of other methods. Due to the significant welding speeds and portability features, the semi-automatic arc is usually used for construction projects.
  3. Gas Tungsten Arc Welding or Tungsten Inert Gas – In this type of welding procedure, a non-consumable tungsten electrode is applied. This is employed in heating the base metal to create a molten weld puddle. The melting of the two different metallic parts results in the creation of an autogenous weld. The process is quite complicated and needs a lot of expertise for perfect execution. One of its advantages, however, is that it can be used to deliver high-quality work with exceptional finishing. This can be achieved without a lot of extra grinding or sanding required to ensure the metal parts are flawless.
