Atom Arc T was developed for welding T-1 steel in all applicati***. Mechanical properties of the welded joints equal or exceed the properties of the base steel in either the as welded or stress relieved condition, thus giving 100% design joint efficiency. In addition, Atom Arc T electrodes are suitable for many other applicati***, particularly where high-strength welds with excellent low temperature impact properties are required.
