Manual Torch Powder Welding

Manual torch powder welding, also called powder welding or puddle welding, uses a special oxy-fuel torch which simultaneously applies powdered metal while fusing the powder onto the area that is being welded. The work piece is preheated, then powdered metal is fed into the flame from a hopper just above the tip of the torch and carried by the gas stream to the surface of the piece. The thickness of the deposited metal is controlled by the rate of flow for the powder and the movement of the torch.

Uses and Benefits of Powder Welding

Because powder welding allows the welder to puddle in small amounts of material relatively quickly, it is often used for repair applications. It can be used to fill in small cracks or gouges or touch up after other fusing methods. Because it is done at relatively lower temperatures, there is less oxidation and deformation of the work piece.
