E71T-1/1M-ULTRA
Alloy Type: A5.20, CARBON STEEL Flux Cored Arc Welding Electrodes

E71T-1/1M-ULTRA is designed for welding 490MPa high tensile steel with both CO2 and Ar/CO2 mixture gas. This baked wire is a titania type of flux cored wire for all-position welding. It provides excellent feedability and soft arc, as well as less spatter generation. E71T-1/1M-ULTRA has very efficient welding due to high deposition rate.
Typical Applications
• Machineries
• Shipbuilding
• Offshore structures
• Bridges and General Fabrication
