Welding_resistance, equipment for economic high quality joining. Special equipment adapted to materials. Automated equipment for automotive applications. Fast, efficient, low cost joining method.
Refractory-metals for corrosion resistance, high temperature service. Joining, welding and brazing. Applications, fabrication, oxidation. Ductile to brittle transition temperature.Interstitial brittle
Hybrid-welding is a most consequential recent development for selected mass scale applications. Slowly evolving towards more common implementations.
Resistance-welding and its applications. Requirements for stainless steel. Spot-welding for "unweldable" aluminum alloys. Coated steel sheets: are they spot weldable? Where is projection welding used?
Metallurgical-expertise is a necessary commodity that must be available to any welding operation. Internal or external it should be always ready to be tapped, for keeping current projects running
SA-welding-tips are essential for selecting and planning one of the most productive processes. Interactive parameters add complexity but also suggest solutions to overcome qualification difficulties.
Brazing-ceramic is a complex subject which requires thorough understanding of basic properties of ceramics and of metals. Successful applications depend on development of suitable materials-procedures
Welding-steel, welding low carbon and low alloy steels by all processes. Know the Weldability of steels and iron base alloys. What makes a material easy or hard to weld. Brittle heat affected zone.
Brazing-nickel needs attention to preparation, filler selection, heating method and protective atmosphere. Provides high temperature strong joints not easily remelted. Electronics, engine applications
Heat-treating of steels is based on a few principles quite well understood. Carbon content and alloy composition play an important part in establishing the outcome of definite thermal cycles.
Resistance-welding-tips may help in setting up welding schedules or for troubleshooting. Introduction to feedback control for consistent performance.
Welding-distortion: cause and effect. How to use residual stresses to straighten welded joints. What to do and how to control warping. How to decrease residual welding stresses. Reducing distortion
