Claims
- 1. A method for using an electrical signal from a pulsing resistance and mechanical force welding process applied across a thin metallic juncture including the following steps:
- monitoring the relative acceleration of a resistance welding electrode during a welding operation,
- providing a signal which is representative of the variations in said electrode acceleration,
- filtering said acceleration signal into that which represents electrode acceleration, and
- adjusting the relative power through said welding electrode to achieve an acceptable electrode acceleration.
- 2. A method for monitoring a welding process according to claim 1 wherein said welder is a high frequency pulse resistance welder for thin metal can body side seams and said adjusting includes controlling the percentage of time the power is available for said electrodes.
- 3. A method of monitoring a welding process according to claim 1 wherein said adjusting includes changing the relative mechanical pressure applied to said electrodes.
- 4. A method for monitoring a welding process according to claim 1 wherein said adjusting is controlling the relative speed of the welding process.
