Which is the best arc welding process for stainless steel?
MIG or Metal Inert Gas welding otherwise known as Gas Metal Arc Welding (GMAW) is one of the most popular and widely used arc welding processes for joining stainless steel and other metals. In MIG welding, the continuous wire electrode is automatically fed to the welding torch at a user-defined speed.See all results for this questionWhen to Use 308L, 309L or 316L Filler MetalCF-8M and CF-3M are the cast equivalents of 316 and 316L, respectively. Use 309L (including ER309LSi) when joining mild steel or low alloy steel to stainless steels, for joining dissimilar stainless steels such as 409 to itself or to 304L stainless, as well as for joining 309 base metal. CG-12 is the cast equivalent of 309.What's the difference between stainless 316 and stainless 316?Below we answer that question and discuss different applications where the grades are used. The most basic difference between the grades of steel is the presence of molybdenum in stainless 316. Molybdenum is a chemical element used for the strengthening and hardening of steel.See all results for this question
What's the difference between argon and CO2 welding?
Previously an Argon/Oxygen mix was widely used, but this doesn't give as smooth a finish as the Argon/CO2 mix. For mild steel welding 80% Argon plus 20% CO2 is common, with 95% Argon plus 5% CO2 often used for thin sections, but even 5% CO2 is too oxidising for stainless and will leave the weld looking black.See all results for this questionWelding of Stainless Steels - Total MateriaStainless steels can be welded using several different procedures such as shielded metal arc welding, gas tungsten arc welding, and gas metal arc welding. These steels are slightly more difficult to weld than mild carbon steels. The physical properties of stainless steel are different from mild steel and this makes it weld differently.Welding of Ferritic / Martensitic Stainless Steels - TWIStainless steels are 'stainless' i.e. are corrosion resistant, due to the presence of chromium in amounts greater than 12%, where it forms a passive film on the surface of the steel. Note that these stainless steels are not the 'stainless steels' that generally first spring to mind; the 18% Cr/8% Ni austenitic stainless steels of the Type 304 or Type 316 grades; but two separate groups of what is the difference between 316 and 410 stainless steel Argon arc welding
Welding of Austenitic Stainless Steel - Part 2 - TWI
Welding consumables must also be selected with low carbon content if best corrosion resistance is required. Most arc welding consumables contain less than 0.03% carbon but there are filler metals available with carbon contents of up to 0.10%; these should only be used to weld the 'H' grades of steel where good creep resistance is required.Welding Stainless SteelWelding Stainless. There are 2 common grades of stainless: 304L (welded using 308L filler), and 316L which is welded using 316L filler. Why is 308L filler used for 304L? Basically there are a number of grades that do similar jobs, 302L, 303L and 304L (they are 17/7, 18/8 and 19/9 respectively). 308L is 20/10 so can be used to weld all 3 grades.Welding Processes for Stainless Steel | Metal Supermarkets what is the difference between 316 and 410 stainless steel Argon arc weldingJul 31, 2019 · Below we discuss the most popular welding processes used for stainless steel.

Selecting a shielding gas for joining stainless steel
Two-part Blends. The two-part blends fabricators of common stainless steels use traditionally are mixtures of argon with either oxygen or CO2. They are suitable for conventional or pulsed spray transfer. If extra-low weld metal carbon content is required for maximum corrosion resistance, argon/oxygen (1 to 2 percent) blends can produce a spraylike metal transfer. These welds have a tough oxide coating that might require postweld cleaning to remove.
