ABSTRACT:
A high-strength low-bolt pipe clamp of the type having rigid lugs fixed to the ends of a flexible band results from an improved method for connecting the lugs to the band. The lugs are of cast material, while the band is of stainless steel. The connection between each lug and the band end is via a pair of initially open jaws on the lug that define a slot in which the band end is inserted. A plurality of spaced holes through the upper jaw of the lug are in registry with holes through the band end when it is inserted in the slot. The jaws are clamped together and deformed toward the band, and a weld is made in each hole to bind the two jaws together permanently and to securely affix the band to the jaws at the weld points. Preferably the weld fills each hole approximately flush with the surface of the lug.
