Arc Welding Service

CATEGORY

TYPE

Metal-powder cored wire without slag for M21

APPLICATIONS

Steel construction, shipbuilding, pressure vessels, mechanical engineering, pipe work etc.

PROPERTIES

AA M3Y is a metal- cored wire which combines high deposition rate typical for FCW with the high efficiencies of solid wire, provides exceptionally smooth and stable arc, low spatter and minimal slag coverage. Extreme low silicate residues on the weld seam.
