A method of producing long low resistance solder lap joints suitable for use on superconducting magnet coils comprising the steps of: securing a first end of a first ribbon conductor to a support; rotating said support to wind said conductor into a coil about said support providing a second end of said conductor; baring a length of said second end of said first conductor; baring a length of a first end of a second conductor; sandwiching said second end of said first conductor and said first end of said second conductor on either side of a flatted length of solder to form a lap joint; bringing a heat source into thermal contact with said lap joint to melt said solder and electrically connect said second end of said first conductor to said first end of said second conductor; moving said heat source along said lap joint while controlling the pressure of said heat source against said lap joint and controlling the temperature of said heat source; and controlling the speed of the movement along said lap joint to provide a uniform low electrical resistance joint.
