i'm a machine repairman and the machines i repair are robotic welding machine. one of the problems we are having is weld slag/expulsion getting caught in the area the cylinder rod moves between the mount and the rod. i tell the engineer to make the hole larger to allow the slag to fall out he says make it smaller to prevent the slag from entering. i tell him to locate some type of bellows to shield the rods. can anyone help me out here. make the holes larger / smaller or where may i look for bellows the can withstand the weld slag and keep that area clean? thanks for any ideas. bob p.
