DUAL SHIELD T-75
Dual Shield T-75 is a flux cored wire with a basic slag system designed for multiple pass welding and produces excellent properties in both the as welded and stress relieved conditions.
Features
Dual Shield T-75 is a flux cored wire with a basic slag system designed for multiple pass welding and produces excellent properties in both the as welded and stress relieved conditions. The exceptional impact toughness and low sensitivity to cracking makes it an ideal choice for a variety of low and medium carbon steels. The arc characteristics are globular, but can be improved with argon gas mixtures. The weld metal analysis is similar to an E7018 low hydrogen electrode.
