Specification:
E71T-1C
E71T-1C is a flux cored wire designed for single or multi pass welding having a smooth arc transfer, low spatter, flat to slightly convex bead contour, with a high deposition rate and easily removal slag. This all-position wire has excellent feeding and low fume generation using 100% CO2 making it a good choice for mild steel and higher strengths steels. Argon - CO2 gases may be used if tested with application.
Purpose:
Most widely used for welding some key structures like shipbuilding, mechanical manufacture, pressure vessels, boilers, petroleum machinery, chemical machinery, hoisting machinery
