<p>A method of lap welding an eventual can blank of a metal sheet or the like by passing a lap joint between the upper and lower roller electrodes via upper and lower wire electrodes to be heated and simultaneously applied pressure, thereby forming continuous thermal press bond sections, wherein the width of the contact surface of the upper and lower wire electrodes is set to three times the width of the lap joint, and the thermal press pond sections are formed by thermal press bonding without fusion, the center-to-center distance between adjacent thermal press bond sections being set to be in a range of 0.8 +/- 0.2 mm.</p> |
