WHAT IS LASER CLADDING?
Laser cladding is a process to apply metal coatings using a precision laser as heat source. The laser melts a formulated powder and welds it to a base metal to create a very strong and durable protective coating, This process extends the life most products / parts that need wear or corrosion protection.
Other names for cladding include hardfacing, hardbanding, surfacing and overlaying. These are essentially all the same, and refer to adding an additional layer to a base material.
WHAT BASE MATERIALS CAN LASER CLADDING BE USED ON?
A large variety of base materials are suitable for laser cladding. Some of the most common base materials include carbon steel, stainless steel, and cast iron.
WHAT ARE TYPICAL CLADDING MATERIALS?
Common alloys applied using laser cladding include Cobalt and nickel-based alloys (Inconels®), stainless steels and Stellite® alloys.
The small dilution layer and fine control of welding parameters makes a large number of materials possible when laser cladding. As long as the clad materials are metallurgically compatible with the base materials they should be able to be used.
