Why is hydrogen added to argon in welding?
Many studies have found that hydrogen is added to argon for welding with nickel as the main ingredient and used for metals such as stainless steels, nickelcopper alloys and nickel base alloys. For other metals it is not recommended as it produces defect hydrogen cracks in the welded metals.See all results for this questionWho are the suppliers of 310S stainless steel plates?Our Company, Asiamet is a well known manufacturer and supplier of stainless steel 310S plates designed and manufactured from high quality raw materials, as per international standards. We have supply of our stainless steel 310S plate products to many countries and all over India.See all results for this questionWhich is the best shielding gas for arc welding?The air is of primary importance for values that indicate the relative density of the shielding gas. It is known that argon and carbon dioxide are gases that have the highest density. Consequently, argon is a gas with high efficiency for shielding around the arc weld.See all results for this question
When to Use 308L, 309L or 316L Filler Metal
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 is the chemical formula for stainless steel Grade 316?Stainless Steel - Grade 316L - Properties, Fabrication and Applications (UNS S31603) Chemical Formula. Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels.See all results for this questionWelding of Austenitic Stainless Steel - Part 2 - TWIWelding 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.
