TIG – How To Tig Weld
Tig welding, Once you learn to TIG weld, It is more likely that the most versatile welding allows you to weld more kinds of metals than any other form of welding. The process can be used to weld steel, aluminum, stainless steel, copper and bronze, nickel alloy, bronze and gold also.
TIG Tungsten Inert Gas media, and is a process in which a tungsten electrode is used to heat and melt the metals to be soldered. The gas is used as a shield around the weld which protects the pool or puddle of atmospheric contaminants, eliminating the need for any stream.
To learn how to TIG weld you need to configure the machine and associated parts such as gas and torch in addition to holding the filler metal rod for what you will be welding. As its many types of tig machine the best establishment can be found in the owner's manual. Before you begin verify that the tungsten electrode is ground to a point. This should be done in a way that the grinder grinding is done as a grinding straight, which means the grinding marks are running the length of the electrode and not around it.
To begin welding hold the torch at an angle of between 70 and 80 degrees, be sure not to touch the job with the tungsten electrode, as this may cause contamination. Hold the tip about of 1/4 – 1/8 inch Th above the work to enable the bow. To start with the practice of control of “plays” in about soldering 1/4 inch wide.
Once you have control of the pool you can insert the welding filler rod. This must be added through a DAB and not a continuous feed. The process should be smooth and controlled, It might take a little practice. Always use the push method using the Tig torch.
TIG welding is a very clean process in comparison with other methods. There is very little smoke or smoking unless the base metal is contaminated. There is no slag or splatter associated with this which makes it more desirable for situations that require a touch of cosmetics, such as works of art in metal or furniture, for example. Once you learn to tig weld you will be convinced that it is the most superior of all welding techniques.
