Laser cladding compared with TIG welding to repair and refurbish railway axles

Laser cladding is a thermal process for depositing a metallic alloy on to a parent metal to repair corrosion, erosion, wear or other physical damage. The present work studies the effects of the laser cladding process on the integrity of railway axles, especially the bond between the cladding layer and the base metal. It also evaluates some physical characteristics of the cladding layer, in this case grade 420 stainless steel. The research concludes that, due to the small size of the heat-affected zone, this thermal process does not adversely affect the physical properties of the axles.
