What amperage is best for TIG welding stainless steel?

What amperage is best for TIG welding stainless steel?

What amperage is best for TIG welding stainless steel?

Setting amperage for tig welding stainless lap joints But stainless only requires about 2/3 of one amp for every one thousandths of thickness. For all you metric folks, your rule of thumb is 40 amps per 1mm. So for this 1/16″ thick (1.6mm) stainless , about 45 amps worked very well.

Can a TIG welder weld stainless steel?

Stainless steel can be stick welded, shielded metal arc welded (MIG), or gas tungsten arc welded (TIG).

What is the best tungsten for welding stainless steel?

thoriated red electrode
What color Tungsten should be used for stainless steel? The thoriated red electrode is ideal for stainless steel welds. It provides the optimal heat generation, bead formation, and weld penetration to give smoother welds.

What color tungsten do you use for stainless steel?

red TIG tungsten
What color tungsten is for stainless steel? The red TIG tungsten is the most commonly used electrode because the 2% thorium mixed with the tungsten is durable and versatile. The thorium allows for easier arc starts and higher current-carrying capacity.

Can you weld 18 gauge steel?

When the material is 18-gauge and thicker, you may be able to use a . 030-inch wire. To weld mild steel, choose an American Welding Society classification wire such as ER70S-6, which has a weld puddle that wets out nicely. Always use a higher argon-based shielding gas, such as 75% argon/25% carbon dioxide.

What is the thinnest metal you can MIG weld?

How thin can you weld with MIG welding? If you can control the amount of heat, you can even weld on virtually any sheet below 0.8 mm using MIG. However, we suggest that you use MIG for metals thicker than 0.6 mm. Ideally, you should use TIG for sheets 0.6mm or thinner.

What kind of welder do I need to weld stainless steel?

Stainless steel can be welded with shielded metal arc welding (MIG), gas tungsten arc welding (TIG) and stick welding, and each of these processes will yield a slightly different result.
