EUSENE DieTZSEN CO.. CHICAaO. 29 coiicLUSioirs From an investigation of the results of all the tests of v;elds,made by the resistance method of electric welding, it is seen thatthe T7elds having the best efficiency were made v/ith a smallervalue of current than was used in making the welds of the same sizi;having a poorer efficiency, hut the current in the first case wasapplied for a greater length of time. This was found true forlengths of time up to a critical point, after which further ap-plication of the current burned the metal at the Joint, therehydecreasing the efficiency of the weld. The increase of cross-sectional area at the joint, due topressure applied does not effect the efficiency of the poorer weld:: ,because this increased area was composed of burned metal, forcedout from the center of the weld, as shov/n by an investigation ofthe ends of the broken specimens. A study of the high efficiencywelds shows that the Joints in most cases were slightly bulged,but the material
