Stainless Steel Welding Electrode
FRW-S309
Accoridng to: AWS A5.4 E309-16
Application: The welding electrode is appropriate for welding low alloy steel, martensitic and ferritic stainless steels with low toughness, and dissimilar stainless steels between carbon and stainless steel. When surfacing 308 series stainless steel on carbon steel or low alloy steel, bottom welding is used to join the stainless steel cladding. applications in the chemical, petroleum, thermal power, and other industries.
Characters: With a main composition of 22%Cr-12%Ni, titanium calcium type stainless steel hand electrodes have a stable arc, beautiful forming, fine corrugation, minimal splash, easy slag removal, excellent coating fire resistance, and good porosity resistance. The weld metal has a low susceptibility to cracks and contains more ferrite.
Attention:
1.The welding speed should not be too slow to prevent overheating and slag inclusion, but in the case of easy cracking, small current and slow…
