Excelloy 77 AC/DC + :

For severe abrasion and moderate to heavy impact

Excelloy 77 is a high alloy solid core electrode offering an excellent combination of abrasion resistance, impact resistance, and weldability. Weld deposits are uniform with excellent bead appearance. Out of position welding characteristics are superior. Developed for use on earth moving equipment, crushers, hammers, and other equipment subjected to severe abrasion and impact. Excelloy 77 bonds readily to carbon steels, low alloy steels, and manganese steels. Weld deposits will cross check to relieve stress.


Welding Procedure

AC or DC reverse polarity can be used. DC reverse will produce highest deposition rates. Stringer or weave beads can be used with a two layer limit.
