Alloy Steel Flux Cored Wire Heat Resistant Steel FRW-81B6 Accoridng to: AWS A5.29 E81T1-B6C Application: It is used for welding of high temperature and high pressure pipelines, synthetic chemical machinery, petroleum cracking equipment, etc. working under 550 ℃, such as Cr5Mo steel. Carbon Steel Flux Cored Wires Features: The arc is soft and stable, less splash, beautiful shape, good slag removal, less smoke and dust, and has excellent welding process performance. Attention: 1. In order to avoid cooling cracks in the weld, appropriate preheating can be carried out according to the steel grade and workpiece thickness, and the corresponding inter-track temperature can be controlled. 2.When welding in a windy place, a wind barrier should be used, which is to prevent the occurrence of pores in strong winds 3.When stored, take moisture-proof measures and do not expose the welding wire to the air for a long time Category AWS standard Chem…
