am changing my BOV and i wanna try to untig the whole flange so i can provide the next person to own this with a simple weld on flange.......

do i go abotu burning the weld joints very carfuly, i know it wont be crazy clean but dealable.....or is there a special tool to do this, i am familiar with migin and tigin machines and diff temps and gases but i just wanna get this done rifght way..........gogin to see welder on thursday but wanna know what im in for...thanks guys

 

I THINK you can just put really high amperage to the welding point and melt it off, but it would look like ****

 

just bring charge pipe to a machine shop and they'll cut it off with a plasma cutter

 

cut off with a die grinder or cut off wheel. Plasma cutters will leave slag just like a torch.

 

You need to keep the flange but not the intake piping? You can use a Tig torch to melt off the piping but unless you have a really steady hand it would be easier to use a die grinder/cut-off wheel/Dremel like stated above.

HackSaw or Zawsall will cut that off no problem.

Ummm I do know what I'm doing. And yes it will leave some slag. Every try to cut through really thick plate? I suggest this because not everyone has alot of experience/PATIENCE to do some jobs. For this application a plasma cutter isn't a good solution and .040 cutoff wheel will do a better job.

 

"un-tigging" = cutting

There is no way to undo the weld with the TIG process because the base metal is melted...what was there is no longer there in the same exact condition as when the welding was initially performed...you'll just have to carefully cut/plasma cut the part off.

 

do not use a torch.. use a plama cutter or air arc it.
