摘要： Embodiments of welding systems (100) and of a welding method are disclosed. A welding system (100) includes a waveform generator (107) to generate a welding waveform with an adjustable DC offset and duty cycle. A sensor (139) of the welding system (100) senses a welding parameter at a welding electrode during a welding operation. A controller (110) of the welding system (100) is coupled to the sensor (139) and the waveform generator (107) and compares the welding parameter to a pre-defined parameter. The controller (110) adjusts at least one of the DC offset and the duty cycle of the welding waveform in response to comparing the welding parameter to the pre-defined parameter to control a stick-out distance of the electrode.

摘要： A hot-pressed member is formed using a tailored blank material obtained by butt joining respective ends of two or more coated steel sheets. The hot-pressed member has two or more sites formed by the respective coated steel sheets and at least one joining portion between the sites. Depending on a type of a coated layer of each of the coated steel sheets, t w /t 0 is appropriately controlled where t w is a thickness of a thinnest portion in the joining portion and t 0 is a thickness of a thinnest site of the sites. A tensile strength of each of the sites is 1180 MPa or more.

摘要： A purge dam assembly confines a volume within an assembly of pipes, including a distal pipe and a proximal pipe together arranged for butt welding at a seam. A distal disk is covered at its periphery with a distal bootie including gasketing material. A proximal disk is covered at its periphery with a proximal bootie including the gasketing material. The each disk is sized such that the bootie contacts but does not completely seal against an inner surface of one of the tubes or pipes permitting a purging flow of gas from the volume and past each disk. A cross-member having a proximal and a distal end, the proximal end is affixed to the proximal disk and the distal end is affixed to the distal disk to preserve the spatial separation between the proximal disk and distal disks and to maintain the proximal and distal disks in coaxial alignment.

摘要： A production monitoring system (100) has a production monitoring server (120), a network communication system, production monitoring data store (130), and production monitoring module (135). The system (100) is configured to receive, from multiple construction locations, information relating to weld locations, welding parameters, and inspection status for individual welds. Welding information is stored within data stores (130) and is retrieved on request to generate inspection reports containing weld locations, welding parameters, and inspection status for individual welds. Inspection reports can be delivered remotely to a plurality of electronic devices (150) and may contain data from x-ray or ultrasound weld inspections. Weld location may be generated by GPS or by one or more location sensors. The system (100) can receive updated inspection information and update the corresponding information in the data store (130). Inspection reports can incorporate welding information within a two-dimensional map or three-dimensional model of a construction location.

摘要： Inductive heating is added to a metal working process, such as a welding process, by an induction heating head. The induction heating head is adapted specifically for this purpose, and includes one or more coils 36 to direct and place the inductive energy, protective structures, and so forth. Productivity of a welding process may be improved by the application of heat from the induction heating head. The heating is in addition to heat from a welding arc 50, and may facilitate application of welding wire electrode materials into narrow grooves and gaps, as well as make the processes more amenable to the use of certain compositions of welding wire, shielding gasses, flux materials, and so forth. In addition, distortion and stresses are reduced by the application of the induction heating energy in addition to the welding arc source.
