Nelson TBA internally threaded aluminum studs are available with weld base diameters of 1/4” through 1/2", with thread sizes of #10-24 through 1/2-13. They are used as mounting points on aluminum structures. They are welded using ceramic ferrules in conjunction with argon as a shielding gas.
The shielding gas is introduced to the weld area through a gas foot assembly, #751020000, which is used for all diameters of TBA 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. The minimum length of Nelson TBA studs, shown below, is the before weld length of the stud, and is dependent on the thread depth.
