Prevention of burn-back when tungsten arc (tack) welding small diameter tubes of differing wall thicknesses
Technical Report
·
OSTI ID:6928598
Tungsten arc tack welding two tubes of differing wall thicknesses resulted in defective welds due to a melt-back of the thinner-walled tube. To solve the problem, a heat sink was applied near the joint. The heat sink dissipates heat from the thin-walled tube, and a satisfactory weld is achieved.
