FUSION AP
ALL POSITION HARDFACING WELD WIRE FOR HIGH ABRASION AND IMPACT
FUSION™ AP
FUSION™ AP is an all positional flux cored wire for hardfacing of components exposed to metal to metal wear, impact and high abrasion. It has the capability to be applied in a single or multiple passes, leaving a good appearance and high-quality weld deposit. The wire has been developed to operate in spray transfer mode whilst welding in all positions, producing low splatter levels. FUSION™ AP has a microstructure that consists of small carbides suspended in a medium alloy martensite matrix allowing for good abrasion and impact resistance.
FUSION™ AP is an all-position, gas shielded hardfacing wire designed for general purpose use. The deposit is a specially formulated wear resistant alloy which produces a uniform distribution of small primary carbides in a martensitic matrix. FUSION™ AP boasts greater wear resistance over other solutions. FUSION™ AP possesses excellent resistance to impact and plastic deformation. The material is characterized by a high hardness and excellent wear resistance. FUSION™ AP is recommended for parts where cross checking is undesirable. FUSION™ AP offers improved weldability over chromium carbide and many other welding wires.
Common applications include:
- Buckets/Shovels
- Chutes/Hoppers
- Dredge Parts
- Forestry Equipment
- Mining Track Beds
