High Wear & Corrosion resistance
coating on Oil & Gas valves

Metal Additive manufacturing for industry 4.0

laser metal deposition- LMD/Laser Cladding

Inner diameter laser cladding for Oil & Gas valve bodies from 2" to 16 " Size

Laser hardening for many applications to enchance the hardness instantly & no environmental pollute sabstance or consumable used


"Pruna Industries LMD Cladding technology" is used to create wear and corrosion-resistant coatings that are 100% dense and metallurgically bonded to the substrate. The LMD cladding process inputs minimal heat to the part compared with PTA, TIG and MIG weld processes. LMD provides very low dilution between the coating and substrate and allows for fine deposit microstructures, precise control of the coating thickness and reduced distortion into the base part. For wear resistance, a variety of nickel, cobalt, and carbide-based powders can be used.

LMD Part Repair Technology

Pruna Industries LMD Part Repair technology can be used to rebuild damaged or worn areas of valuable machine components, dies or molds. LMD produces 100% dense, metallurgically bonded features to the damaged part, with layer thickness from less than 1 mm and up, thus enabling a variety of repair applications that require minimal post-process machining. .

Laser Hardening

Laser hardening is a method aimed at improving component wear behaviour. During laser hardening, also known as surface layer hardening, the energy from the laser beam is applied directly to the component surface. ... Self-quenching is produced as a martensitic structure is formed and the hardening layer is cooled.
