| Uses of TIG Welding Methods | |
|
TIGW is the method that is most commonly applied to the welding of Steels and nonferrous metals as Aluminum and Magnesium. However, with a little variation in the technique and with reversal of feed metal types the TIGW can be used for the welding of a host of other materials. The notable fact is that TIGW works well on all metals with the exception of Zinc and Lead. The application of Tungsten Inert Gas Welding is immense in the industry standards as such and is nearly applicable to all the welding requirements of the world but is not applied in some cases as there are other cheaper options available in the market. An apt example to this regard is the application of TIGW in the welding of Carbon steels where the process is applicable though it is not used due to the presence of other economical options for the same purpose. The following metals are welded using the technique of Tungsten Inert Gas. Aluminum and Magnesium- these metals react actively as soon as they are exposed to the atmospheric conditions of the general standards and form oxides and other compounds that can hinder the basic purpose of welding upon these metals. An AC supply is used for the welding procedure to fall in place however DC is also applicable though there are a variety of other precautions that need to be taken to ensure the workability of the process. In the case of Aluminum the welding area must be preheated to a temperature of 175 degrees to 200 degrees centigrade. In the case of Magnesium the compartment has to be preheated upto a maximum of 150 degrees centigrade. Steel and Stainless Steel- the selection of proper filler material is important to determine the success or failure of the process due to excessive porosity of the welds. In any case there are other methods for the welding of steels and this is just another method in the long line. But there are certain cases where TIGW is preferred due to the precision of the welds. Copper alloys- TIGW works well in case of the welding operations worked upon copper alloys and the only precaution that has to be taken is in the direction of preventing the entrance of atmospheric gases into the hot chamber where the welding process is being given form. Brass- TIGW is greatly applied in the brass designing industry and again the only norm that has to be kept in the mind is regarding the shielding of the welding workshop from the influence of atmospheric gases. |
