電弧鎔接に就て  [in Japanese] Some Researches on Electric Are Welding  [in Japanese]

An experiment was made as regards the relation of the sectional area of the electrodes and the thickness of plates to are welding current. The results are as follows : (1) The current increase or decrease is proportional to the sectional area of the electrodes. (2) And the current varies practically by a(e^<-bx1>-e^<-bx2>) where x_1 and x_2 are the thickness of the welded plates, a and b constant. From these two results, author has made a diagram which gives the suitable current in electric are welding using any size of electrodes and plates.
