Abstract
A method for welding parts using the thermo-electrical output of the metals to be welded to control and evaluate the welding process in which a single energy pulse, such as an electric current or a laser, containing a known amount of electricity is applied to the metals to heat the metals to be welded. Then the thermo-electric output of the metals to be welded is used to determine the mass of the metals. The energy necessary to effectively weld the metals is then determined as a function of the mass.

A method for welding metals using the thermo-electricity output of the metals to be welded to control and evaluate the welding process comprising the steps of:
- (a) applying to the metals to be welded a single energy pulse containing a known amount of energy whereby the energy pulse heats the metals to be welded;
- (b) determining the thermo-electricity output of the metals to be welded to determine the mass of the metals to be welded as a function of the rate of cooling;
- (c) determining the energy necessary to effectively weld the metals as a function of the mass of the metals as determined by the thermo-electricity output therefrom;
- and
- (d) applying the welding current containing the determined energy to effect the weld.
A method for welding metals using the thermo-electricity output of the metals to be welded to control and evaluate the welding process comprising the steps of:
- (a) applying to the metals to be welded a single current pulse containing a known amount of energy whereby the current pulse heats the metals to be welded;
- (b) measuring the resistance of the metals to be welded as a function of the current pulse and its voltage and measuring the mass of the metals to be welded as a function of the rate of cooling as determined by the level of the thermo-electricity;
- (c) determining the energy necessary to effectively weld the metals as a function of the resistance of the metal to be welded and the mass of the metals as determined by the thermo-electricity output therefrom;
- and
- (d) applying a welding current containing the determined energy to effect the weld.
