If you're working in the power, oil and gas, aerospace, petrochemical, or industrial equipment industries, you probably use welding techniques regularly to bind metals. There is a better way to bind metals, and that is a process known as laser cladding. This process utilizes metal powder alloys to enhance the binding process. A laser is used to create a melt pool on the piece that needs to be bound, and then the metal powder alloy is fed through into the weld puddle. This creates a clad layer, which achieves a complete metallurgical bond. This method is fully realized by melting the surface of the piece while the powder is being applied. Below are some of the unique advantages laser cladding has over other welding techniques.
High Purity, Low Dilution Overlay
The chemistry of the target surface is undiluted after a first pass. The hardness of the metal is maintained, so there is no need for multiple passes or a lot of overlay thickening that would only add to the expense of the project and create a lot of tensile stress.
Low Heat, Low Distortion
Parts with low heat tolerances can be bonded with little worry of distorting the dimensions of the product. Laser cladding has been successfully used on pieces as thin as 1.5 mm without any dimensional deviation.
Alloyed Bonds
The bonds in these processes are not mechanical but rather molecular. This makes the product a lot tougher than its welded counterparts, and it can withstand rough abrasions and heavy impact stress.
