Why is MIG welding stainless steel so difficult?
The reason many say that MIG welding stainless steel is difficult is that without proper training you can easily ruin the base metal. The main thing that you want to keep an eye on is that you do not want the base metals to become too hot, because then the carbon will mix with chromium forming chromium carbide which is not corrosion-resistant.See all results for this questionWhat kind of welding is used for martensitic stainless steel?Welding consumables matching the base metal composition are available for most of the martensitic stainless steels, often with small additions of nickel to ensure that no ferrite is formed in the weld.See all results for this questionWhat kind of electrode is used to weld stainless steel?Stainless electrodes with higher alloy content are used so the admixture of the mild steel into the stainless weld deposit does not form an unsatisfactory alloy. Swanton used E309 as it is the commonly used filler metal for joining mild steel to 304 stainless steel. Finishing TouchesSee all results for this question

Welding of Ferritic / Martensitic Stainless Steels - TWI
Stainless 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 alloys with different Welding Guidelines for Stainless Steel and Nickel AlloysThese guidelines are intended as a step-by-step aid to the successful welding of stainless steels and nickel alloys. Step 1: Selection of Filler Metal Alloy for Welding Process. When both base metals are the same, use the base metal alloy as a guide. For example, if joining 316L to 316L, use 316L filler metal.Welding Carbon Steel to Stainless Steel - Swanton WeldingSwanton Welding was asked to fabricate two furnace shells made of A36 Carbon Steel and 304L Stainless Steel. We have worked with this customer previously, and they are well aware of our large fabrication capabilities and the advanced welding ability of our team.

Weld prep strategies for stainless steel
Working with stainless usually requires a more veteran welder or operator than one working with carbon steel, which tends to be more resilient. It can to be less forgiving when introduced to certain parameters, especially in the welding process. Because of the high cost of stainless steel, it makes sense for a more experienced operator to work with it. People usually buy stainless steel because of its finishes, said Jonathan Douville, sSee more on canadianmetalworking stainless ehg steel and metal WeldingWELDING OF STAINLESS STEELS AND OTHER JOINING During the welding of stainless st eels, the temperatures of the base metal adjacent to the weld reach levels at which microstructural transformations occur.
