Re: [MW:13655] Thermal Cutting Procedure for Clad Plate(SA 516 Gr 70 + Alloy 825) / Please Share

Dear Vino,

There are two options 

1. Mark the cutting line, Carry out gouging using plasma hand held torch (optionaly) if you have mechanised edge preparation unit you can make a groove to remove the inconel layer (4mm), then cut the CS portion as normal oxy-fuel tourch

2. Mark the cutting line on the CS side and start cutting.  for SS clad I have done and succeeded but I am not sure this will do for 825.
