Characteristics and Application

AWS A5.20 E71T-1CJ 12CJ Flux Cored Arc Welding Wire is a gas-shielded flux cored wire designed for mild steel and 490N/mm2 high tensile steel. it is suitable for all position welding. It features include stable arc, less spatter, easy slag removable, excellent X-Ray inspection, low diffusible hydrogen (less than 5 ml/100g) and good temperature impact value due to 0.4%Ni in weld metal. The typical applications are shipbuilding offshore, storage tank, pressure vessels, piping etc.
