SAW Hardfacing maximum thickness

[Weldbro]

Can anyone suggest what is the maximum single layer thickness that can be achieved in SAW hardfacing. 

[Dinesh Somwanshi]

Generally its coming 3-4 mm.

Dear WeldBro,

Generally speaking, by using larger-diameter wires, increasing the overlap (much above normal 50%), lowering the travel speed, having a higher voltage and so forth, you can achieve layers with higher thickness. Of course, it all depends on the qualification test results which will eventually put a limit on it.

Connect the Electrode in Negative terminal, u will get higher thickness.
