Re: [MW:4745] Back gouging of SS

Dear Mr. Hegde,

 

In  1994 we tested carbon arc rod gouging for back gouging on duplex stainless steel, and tested the sample welds . At that time we did not discover any contamination of the ss with carbon. We did grind the gouged groove to such extent, that a smooth bevel was arranged.

 

best regards,

Dear Mr Hegde,

 

Attached herewith are 2 articles relating to your requirement. In my opinion Plasma Gouging

is thebest alternativen You can ask for demo from any Hypertherm dealer, if you do not

possess the Plasma Cutting Machine
