Why argon gas is used in MIG welding?
Inert gasses used for MIG welding are Argon and Helium. The term inert means they do not react to anything unlike non inert gasses like oxygen that will cause metal to rust. The gasses used are what shield the weld from the air that causes weld defects such as porisity. Read full answer here.Why Does Argon Arc Welding Produce Pores And How To Sep 12, 2020 · However, due to the weak wind resistance of argon arc welding, it is particularly sensitive to rust, water, and oil stains.

Welding of Stainless Steels - Total Materia
The gas metal arc welding process is widely used for thicker materials since it is a faster welding process. The spray transfer mode is used for flat position welding and this requires the use of argon for shielding with 2% or 5% oxygen or special mixtures. The oxygen helps producing better wetting action on the edges of the weld.Welding Forum > Arc Welding 316L Stainless to Mild SteelMar 20, 2008 · 316 would be better,especially if you wish to leave the weld as a feature. a dissimilar rod or 309 will corrode with the salt water, but so will mild steel. give the mild steel a good coating, but you probably already know that. the weld will probaby rust after a Weld Corrosion of 316L Marine Grade Stainless in Salt WaterApr 21, 2012 · You may be losing your alloying elements at the weld site to oxidation (Chromium and Molybdenum) so you can try welding at the lowest temperature possible. Feel free to quench your weld too, 316L is stable in its austenitic phase and shouldn't go brittle. Quenching it in water with Baking Soda in it will help prevent pitting corrosion. Leave it in a baking soda solution for 5 minutes or so.

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. Argon/CO2 blends produce less surface oxide, good bead See more on thefabricator why 316l rust Argon arc weldingQUICK-GUIDE Welding ConsumablesSTICK ELECTRODE WELDING BASIC ELECTRODES For steel types S235 (St-37), S275 (St-44), S355 (St-52), NVA, NVA 32/36, NVD, NVD 32/36.
