Abstract

Significances of welding current, speed and electrode force are considered introducing basic parameters for weld formation. These are summarized as follows.<BR>(1) The type of weld formation can be devided into two types according to welding speed.<BR>(2) In high speed seam welding, the nugget enlarges both by the increases of current density δ_s, δ_i and by the increase of heating time T_s T_i.<BR>(3) The weldable current range ΔIa decreases with increased welding speed because decrements of δ_s and δs against the increase of current enlarge and the contacting time T_s decreases.<BR>(4) The welding current to form the nugget increases with increased electrode force because the areas of current path A_s A_i increase and the coefficient of heat conduction h increases.<BR>(5) The weldable current range ΔIa at the same welding speed increases with increased electrode force because the contact lengths between electrodes and plates L_s increase resulting in the increase of the cooling time T_s.
