The welder delivers the current to the welding arc via Welding Process. The moveable orbital welding From setup to troubleshooting, learn more about the basics of TIG welding and get tips for TIG welding success. (1) Shielding gas is used to protect the weld and the tungsten from airborne contaminants and debris. This is true for all advanced TIG machines, and especially The equipment for basic TIG welding is a DC power supply, TIG torch, and a gas regulator connected to a bottle of Argon gas. More detailed information can be obtained by purchasing the TIG Handbook from MILLER ELECTRIC TIG welding (tungsten inert gas) uses a non-consumable tungsten electrode to heat the metal you would like to weld. General Principles. TIG welding tips TIG welding can produce clean, precise, aesthetically pleasing welds on a wide range of base materials — making it a good process for critical welds like those found in aerospace, food and beverage equipment The Principle of TIG Welding TIG welding is an electric arc welding process in which the fusion energy is produced by an electric arc burning between the workpiece and the tungsten electrode. TIG process employs on electrode made from high melting point metal, usually a type of TUNGSTEN, which is not melted swarn* 8/ This booklet is a guide to TIG welding basics. now recommends that, for AC welding, operators should sharpen the tungsten as if they are welding in the DC mode. In most Arc welding processes, the arc is struck from a consumable electrode to the workpiece and metal has been melted from electrode, transferred across the arc and finally incorporated into the molten pool. This form of welding uses argon, sometimes mixed with helium or hydrogen. TIG (Tungsten Inert Gas) welding also known as GTA (Gas Tungsten Arc) in the USA and WIG (Wolfram Inert Gas) in The basic design of orbital welding equipment includes a xed pipe and a moveable TIG welding torch/welding head that moves around the pipe. For less than $ you can convert a DC There are four basic components (Fig.) of TIG welding system namely a) DC/AC power source to deliver the welding current as per needs, b) welding torch (air/water an introduction to TIG welding. During the welding process the electrode, the arc and the weld pool are protected against the damaging effects of the atmospheric air by an inert See Safety Precautions at beginning of welding power source Owner’s Manual for basic welding safety information. That’s it!
