Powder welding – simple and effective for smaller parts

Powder welding is normally applied using an oxy-acetylene torch. The component is heated with the torch and the powder is introduced into the gas stream from a powder hopper before being transferred to the component through a flame. The powder coating forms a strong bond to the base metal by alloying and diffusion. Thus, powder welding results in a smooth, dense coating with a diffusion bond to the base material.

The powder welding technique is typically used for glass molds, smaller parts and repairs and is particularly suited for the repair of cast iron and machined parts, i.e. for building up edges and corners. 

Typical working range

• Deposition rate: 0.5-2.5 kg/hour
• Deposition thickness: 0.2 - 12 mm
• Deposition hardness: 20 - 62 HRC 

Benefits

• Simple to use: 1 step: deposit + fusing
• Strong bonding: 0.2-12 mm thickness
• Smoother surface
