More and more, robotic welding is becoming a viable option for use in heavy fabrication. The sophistication and capacity of modern robot systems is suitable for large structures which require multi-pass welds. Processes used for heavy fabrication such as preheating, gas metal arc welding (GMAW), flux cored arc welding (FCAW), tandem gas metal arc welding […]
Read MoreGas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) are both regularly used for welding aluminum. GTAW is a slow process when compared to GMAW and GMAW is typically used when extremely high weld quality (with respect to porosity) is not required. GMAW works well for welding aluminum in structural, automotive, or thick […]
Read MoreSubmerged arc welding (SAW) is a high deposition rate process when compared to gas metal arc welding (GMAW) or gas tungsten arc welding (GTAW). Certain applications such as large flat panels, girth welds in pipe, or spiral pipe mills can benefit from techniques used to increase the deposition rate, and consequently, the productivity of the […]

Read MoreThe EWI Nuclear Fabrication Center just completed the last high productivity technology demonstration. The first demonstration was completed with AREVA to demonstrate a new machining technology, the second with Babcock & Wilcox to demonstrate an integrated laser/robotic technology for welding tube sheets and the final with PCC to demonstrate and compare Tandem GMAW & Laser […]
Read MoreEWI, PCC, the EWI Nuclear Fabrication Center, and the DOE Office of Nuclear Energy are hosting a high productivity welding demonstration on April 19th. The demonstration is designed to provide fabricators the necessary information and first hand exposure to high productivity welding processes like Laser Hybrid Gas Metal Arc Welding (GMAW) and GMAW Tandem. The […]
