General description:

SM-47A, is a 1% Ni alloyed metal cored seamless wire developed for use with Argon/CO2 mixed M20 and M21 shielding gas. The wire is designed to be used both in the short-arc range (dip transfer mode) for single side root runs and for automated and manual welding of horizontal butt welds plus fillet welds in the spray-arc range. SM-47A consists mainly of metal flux which ensures high productivity. The seamless wire has a stable welding arc with low spatter and excellent visual bead shape. The metal cored wire has a clean, copper coated surface together with exact diameter and roundness which produces stable and even wire feeding. This is of great value when long conduit cables are used and when using any automated welding processes. Mechanical properties have been designed for Charpy impact values ≥47 joule at -60°C.
