An arc welder including an integrated monitor is disclosed. The monitor is capable of monitoring variables during a welding process and weighting the variables accordingly, quantifying overall quality of a weld, obtaining and using data indicative of a good weld, improving production and quality control for an automated welding process, teaching proper welding techniques, identifying cost savings for a welding process, and deriving optimal welding settings to be used as pre-sets for different welding processes or applications.

Systems, methods, and apparatuses for monitoring weld quality

Virtual reality arc welding systems that provide virtual reality simulations for training purposes. Virtual reality welding systems to aid in training welding students may provide intelligent connections to web sites on the internet, overlays of ideal weld puddles, recommended corrective actions based on virtual testing results, simulations of virtual environments with safety hazards, and simulations of relationships between improperly set welding parameters and weld defects and discontinuities.

Systems and methods providing enhanced education and training in a virtual reality environment

Arc welding simulations that provide simulation of virtual destructive and non destructive testing and inspection of virtual weldments for training purposes. The virtual testing simulations may be performed on virtual weldments created using a virtual reality welding simulator system (e.g., a virtual reality arc welding (VRAW) system). The virtual inspection simulations may be performed on "pre-canned" (i.e. pre-defined) virtual weldments or using virtual weldments created using a virtual reality welding simulator system. In general, virtual testing may be performed using a virtual reality welding simulator system (e.g., a virtual reality arc welding (VRAW) system), and virtual inspection may be performed using a standalone virtual weldment inspection (VWI) system or using a virtual reality welding simulator system (e.g., a virtual reality arc welding (VRAW) system). However, in accordance with certain enhanced embodiments of the present invention, virtual testing may also be performed on a standalone VWI system.

Virtual welding system

The present invention is directed to a system and method of remotely controlling a welding machine with command signals transmitted to the welding power source across a weld cable connecting the power source to a remote device, such a wire feeder. A transmitter transmits the control commands containing desired welding operational parameters to a receiver disposed in the power source across a weld cable also designed to carry welding power from the power source to the wire feeder.

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.
