Method for simultaneous resistance brazing of adjacent conductor joints

A method of brazing adjacent conductor joints comprising the steps of:

• arranging at least a first and a second pair of conductor joints in a first row, said first pair of joints comprising a first conductor end portion and a second conductor end portion, and said second pair of joints comprising a third conductor end portion and a forth conductor end portion;
• arranging at least a third and a fourth pair of conductor joints in a second row spaced apart and adjacent the first row, said third pair of joints comprising a first conductor end portion and a second conductor end portion, and said fourth pair of joints comprising a third conductor end portion and a forth conductor end portion;
• placing a brazing compound between the first and second end portions of the first pair and third pair of conductor joints and between the third and fourth end portions of the second pair and fourth pair of conductor joints;
• placing a conductive spacer between the second end portion of the first pair of conductor joints and the third end portion of the second pair of conductor joints and between second end portion of the third pair of conductor joints and the third end portion of the fourth pair of conductor joints;
• sequentially passing electrical current first through the first row of the first pair of conductor joints, the conductive spacer and the second pair of conductor joints so that the brazing compound melts to braze the first and second end portions of the first pair together and the third and fourth end portions of the second pair together, and next passing electrical current through the second row of the third pair of conductor joints the conductive spacer and the fourth pair of conductor joints to cause the brazing compound to melt to braze the first and second end portions of the third pair together and the third and fourth end portions of the fourth pair together.
