Abstract : A flexible trailing shield for providing nonreactive gas shielding to arc welding operations comprises a housing formed of interlocking transverse segments adapted to flexibly cover weld surfaces having varying configurations. The housing has a torch entrance port for slidably receving a welding torch, a conduit for receiving gas into the housing, a foraminous material to uniformly distribute the gas within the housing, and a pervious structure through which the gas is dispersed over the weld surface.
