Anytime you are TIG welding you use 100% argon, not c25 or c10 or c anything. Stainless, mild steel, chromalloy. its all 100% argon. the price differance for argon over c25 will never come close to the amount of money youll spend replacing tungsten,
Best Gas for TIG Welding Carbon Steel Welding Nitrogen is sometimes used as a purge gas when TIG welding stainless steel. It is also used in MIG welding for some applications. Nitrogen works as a purge gas on the backside of a TIG weld because it isnt exposed to high arc temperatures. Purge gas protects the back of a weld (especially stainless steel) from oxidation while its hot.
When TIG welding stainless steel, pulse welding helps reduce distortion by minimising the heat going into the weld while simultaneously optimising penetration. If this is a consideration, make sure your TIG welding machine has pulse welding capability.
How to Solve 10 Common TIG Welding Problems [Guide]Apr 03, 2020 · 8. Sugaring on stainless steel. Figure 8 shows sugaring on the backside of a stainless steel weld. Sugaring (oxidation) occurs around the weld when it is exposed to oxygen in the air. The best way to prevent sugaring is to back purge the weld with argon shielding gas or reduce welding amperage.
How to Weld Stainless Steel - The Definitive Guide for Recommended shielding gas for short circuit stainless steel MIG welding is a tri-mix shielding gas. For example, you can use 90%He, 7.5%Ar and 2.5% CO2. (Source:Lincoln Electric) How to GTAW/TIG weld stainless steel? When welding stainless steel use DCEN polarity and 2% thoriated tungsten. Use Argon as shielding gas.
It is best to have separate work areas for carbon and stainless steel if you have space. 2. Choose a welding machine. The two most common ways to weld stainless steel are MIG welding and TIG welding. TIG welding gives the nicest-looking weld, but it requires more skill. If it doesnt matter what the weld looks like, MIG welding does a fine

Stainless Steels Welding Guide - Lincoln Electricstainless steel is generally helpful in welding. Less welding heat is required to make a weld because the heat is not conducted away from a joint as rapidly as in carbon steel. In resistance welding, lower current can be used because resistivity is higher. Stainless steels which require special welding procedures are discussed in later sections
Jul 08, 2020 · Best Tig Welder for Thin Stainless Steel. What should you look in a Tig welding machine, especially when you are looking for thin stainless steel? Wire Speed:60-600 imp (1.5- 15.2 m/min) 25 mm Dines-style connector 13 ft. (4 m) cable electrode holder 2 Flow gauge regulators Quick Select drive roll for .024 in. (0.6 mm)
What gas is Used for TIG Welding - Shielding Gas for Welding is known as a vast field and updated as per day. Today, one of the highly developed welding technique is TIG welding. Why it is so, because of the using non-consumable electrodes instead of other old welding rods, the other noticeable features is the inert gas use. So, not all gases are used for welding and particularly for TIG welding.
What is Passivation for Stainless Steel Welds? - TIG BrushNov 08, 2020 · With TIG Brushs Stainless Steel Weld Cleaning System, you can also eliminate the time-consuming extra steps of passivation and surface refinishing. Passivation Conclusion The passivation process on many stainless steel welds and components is an unavoidable yet necessary part of the process, but that doesnt mean that you need to keep
Welding of stainless steel to mild steel/ Carbon steel/ Low alloy steel (Temperature upto 600 °F (315 °C) The most common Electrode/ filler wire used to join stainless steel or duplex stainless steel to mild steel is E309L/ ER309L for normal temperature service. For high temperature Nickel base consumables are preferred.
