Nelson Fastener Systems Aluminum Collar Stud CKA

Nelson CKA aluminum collar studs are available in thread sizes of 1/4-20 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 collar on CKL studs is useful in mounting applications where a standoff is needed. The shielding gas is introduced to the weld area through a gas foot assembly, #751020000, which is used for all diameters of CKA 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. Studs are available in before weld lengths greater than the specified minimum length to a maximum of 4-1/8”.
