General Description

AS B-235 is a basic coated electrode especially designed for welding in vertical downwards position, with a relatively large diameter electrode, at a very high travelling speed and high current. Thus, it can replace cellulosic coated electrodes in some circumstances. Weld metal has a high resistance to cracking.

Applications and Materials to be Welded

AS B-235 is especially suitable for steel constructions and machines operating under dynamic forces. Ship building, boiler and pressure vessel manufacturing and pipe connections are among its application areas. It is recommended for the welding of high carbon steels having high (P) and (S) content; high strength ship's plate of A-, D- and E- quality and also for low alloyed and structural steels of similar strength with the electrode.
