• Heat Loss by Conduction into the Electrode Tips in Spot Welding

抄録

Although it belongs to a very fundamental problem in spot welding, it is not yet definitely determined what percentage of the total energy supplied escapes to electrode tips.<BR>We investigated this problem on the spot welding of mild steel sheet of 0.6 mm to 3.2 mm thickness under the welding conditions specified by R.W.M.A. By measuring the welding current and voltage, the total supplied heat capacity was calculated by using H=0.24 IVt(cal.). By the amount of cooling water for electrode tips and its temperature rise in stationary condition, the calorie conducted to electrode tips was obtained.<BR>The calorie used in producing nugget and conducted to sheet from the peripheral of nugget was calculated from the temperature rise of the water in which the test piece had been dipped.<BR>Thus by determining the individual calorie escaping to each part and the total supplied calorie, the percentage of the calories escaping to electrode tips in the total calories supplied could be roughly estimated.<BR>The result proved that the heat loss to the electrode tips depends merely on the sheet thickness and has nothing to do with the welding conditions, A.B.C.
