TIG Welding Stainless Steel: Gas Coverage

Using the appropriate type and amount of shielding gas is an important way to prevent carbide precipitation when TIG welding stainless steel. Typically, pure argon provides the best results when welding thinner austenitic stainless steel, but the addition of small percentages of helium is not uncommon when better penetration and faster travel speeds are desired, … Read more

How to TIG Weld Stainless Steel Effectively: Preventing Carbide Precipitation

In order to effectively TIG weld stainless steel, it is important to consider carbide precipitation TIG Weld Stainless Steel : Carbide Precipitation What is Carbide Precipitation? Carbide precipitation occurs when the chrome and carbon in 300 series stainless steel are drawn out of the material and react to the atmosphere. It occurs between 800 to 1650 … Read more

TIG Welding Aluminum DC Electrode Negative

Does your TIG welding machine have enough amperage to weld thick Aluminum? Are you tired of pre-heating only to find that your tungsten cannot withstand the constant AC arc? Direct Current Electrode Negative (DCEN) or DC(-) TIG welding Aluminum. There are no shortcuts or forgiveness when it comes to welding Aluminum, especially thin material.DC(-) TIG welding Aluminum does … Read more

TIG Welding Aluminum With Direct Current Straight Polarity (DCSP)

Characteristic Of TIG Welding Aluminum With Direct Current Straight Polarity In this process, using helium and thoriated tungsten electrodes is advantageous for many automatic welding operations, especially in the welding of heavy sections. Since there is less tendency to heat the electrode, smaller electrodes can be used for a given welding current. This will contribute … Read more

Tig Welding Aluminium

The TIG (Tungsten Inert Gas) arc welding process is used for welding the thinner sections of aluminum and aluminum alloys. There are several precautions that should be mentioned with respect to using this process. Alternating current is recommended for general-purpose work since it provides the half-cycle of cleaning action. Table 7-22 provides welding procedure schedules for using … Read more
