Weldability of Materials - Nickel and Nickel Alloys - TWI

Nickel and its alloys are readily welded but it is essential that the surface is cleaned immediately before welding. The normal method of cleaning is to degrease the surface, remove all surface oxide by machining, grinding or scratch brushing and finally degrease. Common imperfections found on welding are: porosity.

Superabrasive Grinding 101 | Norton Abrasives

Cubic boron nitride (CBN) is a superabrasive traditionally used to grind steels and nickel alloys. Though not as hard as diamond (4,500kg/mm 2 vs. 9,000 kg/mm 2 ), CBN is not chemically reactive with ferrite-based and nickel alloys, allowing it to outperform diamond-based grinding wheels in life and material removal rates on these materials 1.
