Thanks for the reply unclesyd, I think we have had de nitriding done before, and still had problems, The process requires heating the whole die plate, something you don`t wont to do unless absolutely necessary. The tools are P20 tool steel and can have mirror finish in the cavitys.I don`t know...
Thanks Goahead, I am just hoping someone has a technique not fought of. Nitriding is used extensively in toolmaking because it is a low temmpture process and therefore low distortion.
Hi I work in the tooling industry, and we often repair damaged tools that have been nitrided. For this we use TIG welding, but we usualy have a problem of bubbles forming in the weld, due to nitrogen in the steel from the nitriding process. We grind some off the area and this helps to a degree...
Hi I work in the toolmaking industry, and often we have to repair plastic injection moulding tools made of P20 tool steel that has been nitride hardened. We use tig welding. The end result is usualy poor because of the nitrogen gas, from the nitriding process causes bubbling of weld material...
