Abstract
A process and system for repairing electromechanical cables having an external armor wire layer using a butt welding technique and an arc vanishing machine. A short (break) in a cable having both an external and inner helically wrapped wire layer over an inner conductor(s) is located using conventional techniques. After the inner conductor(s) and inner wrapped layer are repaired (i.e., spliced), the outer wire layers are reconnected using a butt-end welding process and form individual arc shapes. The cable automatically passes through dies on headers to vanish (displace) each of the arcs to the end of the cable. A safety system activates an alarm to shut down the system when a jam occurs before any cable wires break. The system is reactivated after the jam is cleared.

A method of repairing helically wrapped outer cable wires of an electromechanical cable without using a brazed splice or a shimmed splice, comprising the steps of:
- (a) overlapping ends of previously cut helically wrapped outer cable wires of the cable together to form individual loose arc portions in the helically wrapped outer cable wires, each of the loose arc portions being raised above the cable and are spaced apart from one another to form spaced apart points;
- (b) welding the ends in each of the raised arc portions together without using a brazed splice or a shimmed splice;
- and
- (c) flattening each of the raised arc portions in the hellically wrapped outer cable wires until each of the individual raised arc portions are removed, wherein the helically wrapped outer cable wires are repaired without using a brazed splice nor a shimmed splice.
A method of butt end welding helically wrapped outer armor wires in an electromechanical cable that has been repaired for having a short without using a brazed splice nor a shimmed splice, comprising the steps of:
- locating a short within an internal conductor in an electromechanical cable having an outer helically wrapped layer of armor wires;
- cutting the armor wires in the outer helically wrapped layer of the cable to reach the short in the internal conductor;
- repairing the short in the internal conductor;
- butt end welding exposed ends of the cut armor wires together to form individual loose arcs in the helically wrapped layer of the armor wires, the loose arcs being raised above the cable;
- and
- flattening each of the individual loose arcs in the helically wrapped layer of armor wires so that each of the individual loose arcs are removed, wherein the helically wrapped outer armor wires are repaired without using a brazed splice nor a shimmed splice.
A method of repairing helically wrapped outer cable wires of an electromechanical cable without using a brazed splice or a shimmed splice, comprising the steps of:
- (a) overlapping ends of a previously cut helically wrapped outer cable wires of the cable together to form individual loose arc portions in the helically wrapped outer cable wires, each of the loose arc portions being raised above the cable and longitudinally spaced apart from one another to form longitudinally spaced apart points;
- (b) butt-end welding each of the spaced apart points of raised arc portions together without using a brazed splice or a shimmed splice;
- and
- (c) flattening each of the raised arc portions in the helically wrapped outer cable wires until each of the individual raised arc portions is dispersed within the cable, wherein the helically wrapped outer cable wires are repaired without using a brazed splice nor a shimmed splice.
