  • Electroslag welding speed control
    Patent number: 3975614
    Abstract: An improved vertical electroslag welding system wherein the driving motor which propels the molding shoes is controlled by varying its speed in response to electrode current thereby assuring a molten puddle which for any set speed will not rise over the cavity wall or become too fluid. The motor is remotely controlled so that the welding current is not directly coupled to the control circuit.
