Welding Torch Explanation. The arc and weld pool formed using a bare wire electrode was protected by helium gas readily available at that time. The weld metal is that portion of the joint that has been melted during welding.
All welding torch kits are neatly packaged and easy to carry anywhere without taking up too much space. This welding equipment is quite popular with welders because it has an economical price and is also flexible to carry. In the flat position the metal is flat and your welding torch or rod is going to move in a horizontal direction.
Explanation-Welding is the process of joining metallic parts by bringing them into intimate proximity and heating the places of contact to the state of fusion or plasticity.
In this course we will cover everything you need to know to start TIG welding. The arc weld illustrates all the basic features of a joint. Metal Inert Gas MIG welding was first patented in the USA in 1949 for welding aluminium. And fed up to the weld point through a hose to the welding torch head.
