Basics of Welding from Logos Weld



Just like any work of art, welding too requires a thorough knowledge of the basics in order to master its different processes. Here is a simplistic understanding about welding and related topics from Logos Weld Products - one of the leading Weldingrod manufacturing plants in India.
To begin with welding is the process through which materials are joined together to form a firm joint. Usually metals or thermoplastics are used in this process. What makes welding different from the other metal joining techniques like brazing and soldering, is the fact that when two metals are joined together in this process, a decent amount of 'melting' of the metals takes place.

Some of the best welding methods are:

  1. Shielded Metal Arc Welding
  2. Gas Metal Arc Welding
  3. Flux-Cored Arc Welding
  4. Submerged Arc Welding
Shielded metal arc welding uses an electrode which has the flux around it. This flux is the protectant for the puddle around the electrode. The electrode holder on the other hand holds the electrode as it melts away in the welding process. The slag on the other hand protects the weld puddle from atmospheric contamination of any kind. Gas Metal Arc Welding on the other hand uses a wire feeding gun. This wire feeding gun feeds the wire at an adjustable speed and flows an inert gas (Argon gas) or a mix of carbon dioxide and Argon over the weld puddle to protect it from atmospheric contamination.

Flux-Cored Arc Welding is quite similar to Gas metal arc welding. The only exception is that this method of welding uses a special tubular wire filled with flux. Depending on the filler, you can either use or not use the tubular wire. While the Submerged Arc Welding makes use of an automatic fed consumable electrode along with a blanket of granular fusible flux. In this method of welding the molten weld and the arc zone are constantly protected from the atmospheric contamination as it is “submerged” under the flux blanket.
These are some of the basic ways in which welding can be done.
