Relation between electric constants of coils and the result of electromagnetic welding was examined on the specimens consisted of the couple of tube and core bars. Electric constants of apparatus and coils were obtained from the current waves under each condition. The result of welding was estimated for each coil by the acceptable limit of clearance between tube and core bar. As a result, accumulating rate of magnetic energy of coil which was defined as the time differential of magnetic energy was confirmed to be the most important electromagnetic factor. Welded joint became more successful according as the coil with larger accumulating rate was used for welding. The largest accumulating rate was obtained by the coil inductance of 3.3 μH for the apparatus of R_o=7.3 mΩ, L_o=2.38 μH and C_o=912 μF.
