Welding Cast Iron With Inconel. Nickel Alloy Electrodes supplier stockist. Brazing isnt really welding as it doesnt fuse the metal as a weld does.

For TIG-root Inconel welding coupons the anneal-ing treatment does not significantly change the initial weld conditions and maintains part of the white iron structures with martensite in. Ad We supply Inconel 625 600 825 welding electrode filler wire. In this work we have demonstrated the feasibility of cladding a layer of Inconel 625 on the surface of the plates of QT-400 nodular cast iron via the bypass-coupled micro-plasma arc welding with the filler wire of Inconel 625 at the welding speed of 80 mmmin and the total current of 50 A.
This is a danger zone for cast iron during which it is the most unstable and difficult to work.
Stick welding is the alternative method for welding cast iron where the electrode with flux is used. Cast Inconel 738 superalloy which is precipitation hardened mainly by γ phase is extremely susceptible to heat-affected-zone cracking on welding. Step 1 Keep the cast iron out of the range of 150 to 500 degrees Fahrenheit 65 to 260 Celsius. 4061 is also used for welding cast iron and build-up on steels.
