Calorimatric measurements have been made of the net heat transferred to the work-piece in welding with the argon-arc, metal-arc, and SIGMA processes. Ranges of arc efficiency factors are reported for various combinations of methods and materials.nA method is suggested for presenting the distribution of temperature around a point source in one diagram valid for all materials and operating condition. Measured temperatures outside the weld pool are in fair, agree¬ment with theory at a sufficient distance from the weld, hut deviations are observed in regions closer to the weld. A procedure is outlined for the assessment of average bath temperatures from the measured temperature distribution in the parent-plate material.
