Abstract: The invention provides for a method of welding a stud to a work piece using a ferrule, whereby during the stud welding process, the stud is properly centered within a bore of the ferrule and wherein molten weld material formed during the stud welding process is confined to the bore of the ferrule and gases formed during the welding are vented out of the ferrule through an upper portion of the bore. The invention further provides for a ferrule having a body having at least one rib which extends inwardly from an inner wall of the body proximate to an upper surface and which defines at least one groove. During a welding operation, the at least one rib is configured to center a stud within the ferrule, and the at least one groove is configured to allow gases formed during the welding operation to vent out of the ferrule.

Abstract: An abrasion resistant metal earth working surface having a plurality of spaced hollow open ended cup-shaped abrasion resistant studs welded to the surface which collect particulate material in the hollow open ends of the weld studs, wherein the particulate material forms an abrasion resistant barrier limiting abrasion of the earth working surface. The size and shape of the cup-shaped weld studs and the spacing between the array of studs is selected to provide optimum collection of particulate material which reduces wear to extend the efficient operation and life of the earth working surface.

Abstract: A temporary load support system including a permanent portion comprising a stud having a stem and crosspiece, and a removable load support member comprising a cavity, configured to receive the stud and engage the crosspiece upon relative rotation of the support member relative to the stud while the stud is received in the cavity, whereby the support member is removably attached to the stud so as to enable load transfer from the support member to the stud.

Abstract: Improved welding stud (20) includes a generally cylindrical body (34). A first series of annular rings (42) are disposed on a first end portion (18) of the cylindrical body (34). A second series of annular rings (44) are disposed on a second end portion (26) of the cylindrical body (34). The rings (42, 44) are asymmetrical and have reverse configurations. Thus, the annular rings (42) on one end portion of the stud are a mirror image of the rings (44) on the opposite end portion of the stud. Either end of the stud (20) may be stud welded to a base member (14) using the drawn arm short cycle or gas arc stud welding processes. A cap (24) may then be press fitted onto the opposite end of the stud to secure insulation.

Abstract: A stud for use in end welding and having a cylindrical portion with a welding flux and a square portion. The square portion has planar faces through bores. A wire hanger using the cylindrical and square stud with a support leg are secured to the stud and tiers are secured to the support leg for supporting wires, pipes, ducts or other objects spaced from overhead or a bulkhead.
