Nelson Fastener Systems Full Base Threaded Aluminum Stud HBA

Nelson HBA threaded aluminum studs are available in thread sizes of #10-24 through 1/2-13. They are used for attaching parts to aluminum structures. They are welded using ceramic ferrules in conjunction with argon as a shielding gas. The full nominal weld base for the HBL studs gives greater weld reliability and strength than could be achieved using a pitch diameter weld base. The shielding gas is introduced to the weld area through a gas foot assembly, #751020000, which is used for all diameters of HBA studs. Gas hose #515001001 and gas regulator #514001001 are needed to deliver and control the gas flow from a pressurized cylinder. An aluminum Tranquil-Arc plunge dampener kit is also needed as an accessory on the gun to control the rate of the stud’s return in to the molten weld metal at the end of the weld cycle.
