AntiAbrasion Coatings

Hard coating is the process of depositing a harder or harder material onto the surface of another for greater resistance to abrasion, erosion or impact. Hardfacing is a difficult process to master due to the crack sensitive nature of many hardfacing materials. W, H, S, has focused on process controls and extensive research and development to ensure the highest quality of hardfacing. This process is used to extend the life of components in many industries such as oil and gas, drilling tools, mining and petrochemicals, refining, and steel.

Hard coating processes

• GTAW-P-HW (pulsed hot wire for gas tungsten arc welding)
• GTAW (arc welding with tungsten gas or TIG or Heli-Arc)
• SAW (submerged arc welding)
• OAW (open arc welding)
• SMAW (shielded metal arc welding or STICK)
• GMAW (Gas Metal Arc Welding)
• PAW (plasma arc welding)
• PTAW (Plasma Transferred Arc Welding) powder feeding
• PTAW (Plasma Transferred Arc Welding) powder feeding
• The above processes use manual, semi-automatic and mechanized systems
