How to TIG Weld Stainless Steel Effectively: Preventing Carbide Precipitation

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

Tig Welding Aluminum

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

TIG Welding Stainless Steel Basics

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

Tig Welding Stainless Steel

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
