2007 Features Company Takes Its Shop to the Utah Wilderness Job shop specializes in field welding operations Howard M. Woodward P91 and Beyond Properties of creep strength-enhanced ferritic steels and advanced chromium-molybdenum steels used for high-temperature service were examined K. K. Coleman and W. F. Newell Jr. Modular Fixturing Helps Fab Shop Maintain Tight Tolerances Fixturing equipment helps a Massachusetts fab shop produce large-sized, yet precisely manufactured, components Tips for GTA Welding 4130 Chrome-Moly Steel Tubing These suggestions will help you perform better gas tungsten arc welds on this strong, yet malleable, steel. J. Fulcer and J. Fogle Welding Research Supplements Computational Kinetics Simulation of the Dissolution and Coarsening in the HAZ during Laser Welding of 6061-T6 Al-Alloy Results showed it is possible to simulate the microstructure evolution and hardness in the HAZ of heat-treatable aluminum laser beam welds A. D. Zervaki et al. The Influence of Oxygen on the Nitrogen Content of Autogenous Stainless Steel Arc Welds The presence of oxygen in the shielding gas was shown to increase the weld metal nitrogen content, stabilize the arc, suppress degassing, and curb porosity M. du Toit et al. Double-Electrode GMAW Process and Control A novel welding process adds a GTAW torch to a conventional GMAW system to create a bypass arc for increased melting current and a controlled base current K. H. Li et al. A Look at the Optimization of Robot Welding Speed Based on Process Modeling An algorithm was designed to maintain complete joint penetration while maximizing prodcutivity by using the fastest weld speed M. Ericsson et al. Repair Techniques for Fusion Reactor Applications Measurements were made of the effects of helium on the weldability of Types 304 and 316LN stainless steels M. H. Tosten et al. |
