Excelloy 7007 AC/DC+ :

Tubular Hardfacing a unique hardfacing electrode for severe abrasion

Excelloy 7007 is a dip coated multiplex-alloyed electrode designed for extremely economical wearfacing applications. Despite its large diameters this electrode can be used with most common welding power supplies. Economy is enhanced by a 96% recovery rate. Low current density reduces heat input in to the base metal.


Applications

Wherever severe abrasion is encountered such as conveyors, screws, augers, and plow blades.


Procedure

Remove all unsound and fatigued base metal using the Excelloy 56 gouging and cutting rod. Deposit alloy while maintaining a moderately long arc length. Use either a weave or stringer technique. Deposits should be limited to two layers. Crosschecking will occur as deposit relieves itself of internal stresses.
