TIG Welding (GTAW)

What is TIG Welding? Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or helium). Filler metal … 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

TIG Welding Advantages

One of the greatest advantages of  TIG welding, (Tungsten Inert Gas) welding or Gas Tungsten Arc welding (GTAW) process is that it will weld more kinds of metals and metal alloys than any other arc welding process. TIG welding can be used to weld most metals, including aluminum, magnesium, copper, brass, bronze, stainless steel, nickel alloys … Read more

TIG Welding Aluminum With Alternating Current

Characteristics Of TIG Welding Aluminum With Alternating Current (AC) Process Welding aluminum by the gas tungsten arc welding process using alternating current produces an oxide cleaning action. Argon shielding gas is used. Better results are obtained when welding aluminum with alternating current by using equipment designed to produce a balanced wave or equal current in … Read more

The Art of TIG Welding Stainless Steel

When TIG welding stainless steel there are a few points to keep in mind to achieve a cosmetically appealing and sound weld. Because stainless steel does not adequately dissipate heat, maintaining proper heat input when welding is critical. Too much heat can lead to warping, embrittlement, or rust. As little as five amps too much can damage … Read more

TIG Welding 4130 Chromoly Tubing

4130 Chromoly steel has an excellent strength to weight ratio, is easily welded, and is considerably stronger and harder than standard 1018 steel. The 4130 grade of Chromoly or chrome-moly is a high-strength low-alloy (HSLA) steel that contains molybdenum (0.15 – 0.25 percent by weight) and chromium (0.8 – 1.1 percent by weight) as strengthening … Read more
