These articles talk about the basics of tig welding, its advantages, disadvantages, etc. A special focus has been put on tig welding of aluminum and stainless steel. A few of the articles have been devoted to some popular TIG welders used widely in the industry.
A considerable number of people ask about welding machine requirements in order to TIG weld aluminum with direct current. TIG weld Aluminum with Direct Current Electrode Positive (DCEP) or DC(+) Can you TIG weld aluminum without AC and a High-Frequency box? Yes, you can actually weld aluminum with a low-cost DC power supply. It doesn’t make it any … Read more
In order to effectively weld stainless steel with tungsten inert gas welding process, it is important to consider carbide precipitation. TIG Weld Stainless Steel : Carbide Precipitation What is Carbide Precipitation? Carbide precipitation is said to occur when the chromium and carbon in 300 series stainless steels are drawn out of the microstructure and react with atmospheric … Read more
Gas tungsten arc welding, or TIG (Tungsten Inert Gas) arc welding process is a commonly used process for welding of low thicknesses of aluminum and aluminum alloys. This article discusses TIG welding of aluminum with three methods – with alternating current, with direct current straight polarity, and with square wave alternating current. Welding With Alternating Current … Read more
This article talks about the basics of tig welding, starting from what is tig welding, the principles of tig welding process, shielding gas used in tig welding, and advantages of tig welding. What is TIG Welding? TIG welding is also called Gas Tungsten Arc Welding. It is a welding process in which joining of metals … Read more

In comparison with the welding of mild steel, for example, the austenitic stainless steels have several characteristics that require some revision of welding procedures that are considered standard for mild steel. The melting point of the austenitic grades stainless steels is lower, so less heat is required to produce fusion. 300 Series stainless steel electrical … Read more
Known as 300 series, austenitic stainless steels are the most commonly welded. These chrome nickel steels, in contrast to lower-cost stainless have more alloys and are “non magnetic” (Exception, types 310 – 330). Austenitic grades of stainless steel typically contain a minimum of 16-26% chromium and 6-22% nickel. 308 Grade stainless steel, for example, is … Read more
