Abstract: Embodiments of the present invention are directed to systems and methods of predicted a welding property for a given welding operation using at least one electrode. Embodiments determine a predicted weld deposit property and compare the predicted property to a desired property to determine whether or not a selected electrode for the given welding operation can achieve the desired weld deposit.

Abstract: Embodiments of the present invention comprise a system and method to weld or join coated materials using an arc welding system alone, or in combination with a hot wire system, where the arc welding system uses a welding current having an AC current portion to build a droplet for transfer to the workpiece. In further embodiments, the workpiece is coated with a material, such as zinc, and the arc welding system uses an AC welding waveform which is capable of welding coated workpieces with little or no porosity or spatter and can achieve enhanced performance. Additional embodiments use an enhanced electrode to provide optimum porosity performance. Such embodiments allow for the welding of coated material with little or no porosity and spatter, and at a high welding rate.

Abstract: Information from a business application system, such as an ERP system, may be published to a business application user-generated web page for display to an end user and for collecting information from an end user to make available for download into the business application system. The user-generated web page may be defined as a web-based visual representation of a structured data solution, which may define data, data presentation, and data binding metadata for enabling a solution scenario, such as vendor enrollment, sourcing, time entry, job listings, vendor-managed inventory, sales lead capture, purchase order/invoicing, service contract renewal, and customer support requests, and the like. Business application users may be enabled to connect with potential and existing customers, partners, and vendors from within the business application system via the web-based visual representation, and additionally, may capture interactions directly into the business application system without IT dependency.

Abstract: The disclosed technology generally relates to welding, and more particularly to a consumable electrode wire for metal arc welding, and a method and a system for metal arc welding using the consumable electrode wire. In one aspect, a consumable welding wire configured to serve as an electrode during metal arc welding comprises one or more alkaline earth metal elements at a concentration between 0.005% and 10% on the basis of a total weight of the welding wire.

Abstract: The invention described herein generally pertains to a system and method related to a semi-automatic or a manual welding operation and detecting a base material (e.g., workpiece) temperature, communicating the base material temperature, and adjusting the welding operation based on the detected base material temperature. A temperature sensor can detect temperature at a location that is a distance from the arc and, for instance, parallel to a direction of travel of the welding torch and such detected temperature can be communicated to the user performing the weld or the user controlling the semi-automatic welding system. The user can be informed if the detected temperature is within a tolerance or approved range or if the detected temperature is outside the tolerance or approved range for the type of base material and/or pre-defined temperature.

Abstract: A welding system and method is disclosed for girth welding high strength materials using a short arc welding process and a self-shielding electrode. The welding system contains a welding apparatus which advances the self-shielding electrode towards a workpiece to be welded and controls the arc length and the operation of the apparatus so that the weld satisfies the requirements for welding at least American Petroleum Institute Grade X-80 line pipe. The system additionally contains a power source with a controller for creating a current pulse introducing energy into the electrode to melt the end of the self-shielding electrode and a low current quiescent metal transfer section following the end of the melting pulse during which the melted electrode short circuits against the workpiece.
