AWS A5.20 CLASSES E70T-1C/E70T-1M

USA E70T-1 is a flux cored wire for single or multi-pass welds on mild steels and certain low alloy steels. USA E70T-1 is noted for its low spatter generation, high disposition rate and ease of slag removal when used for flat and fillet welds of medium and heavy thickness plates. It has been designed to be used with 100% CO2 or 75-80% Argon + balance CO2 mixed shield gas

Applications:

USA E70T-1 is used extensively in the fabrication
of bridge structures, pressure vessels, earth moving
equipment, general construction, shipbuilding and
whenever welds are required to meet structural and
nuclear codes.
