Where cracking occurs in or adjacent to welded joints, a satisfactory repair can be made by welding. It is important that enough of the cracked material is gouged or machined away to allow a full penetration repair weld, with no traces of crack left and no new significant defects introduced.

Example of Powermax gouging for weld repair:

Customer application

End user needs to periodically repair cracks of special materials such as high Cr-Ni steels and Pure Copper.

Existing method and challenges

Grinding machines and carbon arc. Grinding is slow and carbon arc contaminates the base metal.

Powermax® solution

HyAccess™ gouging consumables which enable a very delicate gouging process without any carbide formation on the base metal.

Powermax results

Customer was able to complete the repair faster and with high precision without contamination.
