Pulse welding techniques for hsla steels have the advantages of improving microstructure, reducing distortion and increasing mechanical properties. the primary objective is to improve reliability and predictability of welding hsla steels. a new advanced sensing system "edap" will provide real time… More

The primary objective of this research is to develop a method that will improve both the reliability and predictability of welding age hardening aluminum alloys. this may be accomplished by using an improved vasr (vibratory aging and stress relief) system, square wave pulsed arc welding, and… More

Automatic pipe welding, for both new construction and repairwelding, currently depends upon operator skill and other controls to assure sound welded joints. additional expensessuch as x-ray inspection combine to make the costs of any necessary rework of welded pipes prohibitive. electrodynamic arc… More
