Abstract
A method for monitoring a spatter generating event during a welding application. The method includes capturing data that corresponds to a welding current of the welding application. The method also includes detecting parameters associated with a short circuit from the captured data. The method includes analyzing the detected parameters to monitor the spatter generating event during the welding application.
Claims20
A weld monitoring system comprising:
- a sensor configured to capture data representative of a welding current of a welding application;
- and
- control circuitry configured to:
- detect a parameter relating to a short circuit from the captured welding current data;
- analyze the parameter relating to the short circuit to monitor a spatter generating event during the welding application;
- and
- determine an amount of spatter generated by the spatter generating event.

A weld monitoring system comprising:
- a sensor configured to capture data representative of a welding current of a welding application;
- and
- control circuitry configured to:
- detect a plurality of parameters relating to a short circuit from the welding current, the plurality of parameters comprising a short circuit clearing current, a duration of the short circuit, and an average weld current;
- analyze the plurality of parameters relating to the short circuit to monitor a spatter generating event during the welding application;
- determine an amount of spatter generated by the spatter generating event by dividing a square of the short circuit clearing current by a product of the duration of the short circuit and a square of the average weld current;
- and
- communicate an occurrence of the spatter generating event, or the amount of spatter generated by the spatter generating event, to a user.
