Air force AF-WELD™ is a state of the art anti-spatter which protects work-pieces from the adherence of spatter. AF-WELD™ is the only anti-spatter on the market which will help you perform porosity-free, crack-free welds while drastically reducing your environmental impact. Compressed air is the only propellant, and you eliminate the disposal of empty aerosol cans and all the associated costs. AF-WELD™ anti-spatter retracts in the presence of heat, leaving the immediate welding area clean and void of liquid. This effectively prevents anti-spatter from chemically interacting with the weld pool during fusion, which can cause porosity and weld rejection. AF-WELD™ improves productivity and weld quality!
