Abstract

A method for resistance welding first and second sheet metal elements together by placing a copper shunt between and in contact with a first sheet metal element and a third sheet metal element, the third sheet metal element being spaced apart from and connected to the first sheet metal element. Then placing a second sheet metal element in contact with the first sheet metal element along an interface between the first and second sheet metal elements and pressing a first electrode against the second sheet metal element, pressing a second electrode against the first sheet metal element, and passing a welding current between the electrodes through the copper shunt and welding the first and second sheet metal elements together along the interface.

Claims

exact text as granted — not AI-modified
1 - 17 . (canceled)  
   
   
       18 . A method for resistance welding first and second sheet metal elements together, the method comprising: 
 placing a copper shunt between and in contact with a first sheet metal element and a third sheet metal element, the third sheet metal element being spaced apart from and connected to the first sheet metal element,    placing a second sheet metal element in contact with the first sheet metal element along an interface between the first and second sheet metal elements,    pressing a first electrode against the second sheet metal element,    pressing a second electrode against the first sheet metal element, and    passing a welding current between the electrodes through the copper shunt and welding the first and second sheet metal elements together along the interface.    
   
   
       19 . A method as claimed in  claim 18  wherein: 
 the first sheet metal element is a flange connected to the third sheet metal element,    the flange is connected to the third sheet metal element by a hem, and    the copper shunt is placed in a gap between the flange and the third sheet metal element.
