摘要

A kind of apparatus and method of the low resistance welding of sheet metal with high circulation rate, have following features：A) main bodies (1) formed in a manner of U-shaped,Lower lifting drive component (2) positioned opposite to each other and upper lifting drive component (7) are configured with two horizontal fixed feets of main bodies (1),Wherein in force direction,Bottom electrode fixing device (3) follows the lower lifting drive component (2),And top electrode fixing device (6) follows the upper lifting drive component (7),B) by the fixed lower welding electrode (11) of the bottom electrode fixing device (3) and the fixed upper welding electrode (5) of the top electrode fixing device (6) is passed through,Wherein described lower welding electrode (11) carrying configures and is tapered to lower imprint head (10) a little between two parties in each case,And imprint head (8) in upper welding electrode (5) carrying,C) strips for joint parts feeding means (4),The strips for joint parts (9) that will be soldered is transported to described two imprint heads (10,8) intermediate space between,D) power supply,Its supply is applicable in the welding current of the strips for joint parts (9).
