Abstract
A welding system or an enterprise using welding systems can communicate with cloud-based resources for the provision of services and products to facilitate the welding operations. The communications may be via wired or wireless media, and may be direct, or through other components, such as enterprise networks, peripheral devices, and so forth. The cloud-based resources may provide for storage of data, particularly welding data, processing of data, welding protocols, specifications and processes, financial transactions for the purchase, licensing or use of welding-related products and services, welding training, and so forth.
Claims10
A welding system, comprising:
- a welding torch;
- a base unit configured to supply the welding torch with a pulsed electrical current for producing a welding arc between the welding torch and a work piece;
- a voltage sensor;
- a current sensor;
- and
- control circuitry coupled to the voltage sensor and the current sensor, wherein the control circuitry comprises a processor configured to detect signals relating to the pulsed electrical current via the voltage sensor and the current sensor, to store in memory a pulsed waveform based on the signals as an idealized pulsed waveform, to detect subsequent signals relating to a subsequent pulsed electrical current supplied to the welding torch, and to compare a subsequent pulsed waveform based on the subsequent signals with the idealized pulsed waveform.
A welding system, comprising:
- a welding torch comprising an electrode;
- a base unit configured to supply the welding torch with pulsed electrical signals for producing welding arcs between the welding torch and a work piece;
- and
- control circuitry comprising a processor configured to:
- detect a first set of signals relating to a first pulsed electrical current supplied to the welding torch by the base unit;
- store in memory a first pulsed power waveform based on the first set of signals;
- detect a second set of signals relating to a second pulsed electrical current supplied to the welding torch by the base unit;
- compare a second pulsed power waveform based on the second set of signals with the first pulsed power waveform;
- quantify a difference between the first pulsed power waveform and the second pulsed power waveform;
- and
- determine an extension of the electrode relating to the second pulsed power waveform based at least in part on the difference.
