Abstract
A method to diagnose a failed weld in a welding process includes monitoring a location of a weld created on a plurality of work pieces, diagnosing the weld as a failed weld based on said location with respect to a closest edge of one of the work pieces, and identifying said failed weld based on the diagnosing.
Claims19
Method to diagnose a failed weld in a welding process, comprising:
- monitoring a location of a weld created on a plurality of work pieces;
- diagnosing said weld as a failed weld based on said location with respect to a closest edge of one of said work pieces;
- and
- identifying said failed weld based on said diagnosing.

Method to diagnose a failed welding process, comprising:
- monitoring locations of a plurality of welds created on a set of work pieces;
- determining a weld strength for each of said welds based on said locations with respect to a closest edge of one of said work pieces for each weld;
- determining a resulting strength in said overall set of work pieces based upon compilation of said weld strengths;
- and
- identifying said failed weld process based on said resulting strength in said overall set of work pieces.

Apparatus to diagnose a weld failure in a welding process, comprising:
- a control module, including programming to:
- monitor a location of a weld created on a plurality of work pieces;
- determine a distance from said location of said weld to a closest edge of said work pieces;
- determine a predicted strength of said weld based upon said distance;
- compare said predicted strength of said weld to a required strength of said weld;
- and
- diagnose said weld failure based upon said comparing.
