The application applies to a vertical vessel with multiple sections/levels of 1/2" plate w/holes, with (2) layers of screen applied on top of the 1/2" plate for filtering. The screen is held down with 1/4" Rd Bar which is welded to the plate.
Because of the circumference of the vessel, screen protection has proven to be difficult.
I agree with the process that you are speaking of as long as the individual takes the time to protect the screen properly. (as sad as it is, this is always a problem)
I thought that maybe there might be a "miracle" gas that would be more appropiate for this situation, even if it is not so cost effective.
What do you think about running wire smaller than .035 to eliminnate or lessen possible "fireballs, bb's" (not sure of correct lingo) when the welder loses his/her lead angle of the gun?
