Laser ultrasonics can be used to nondestructively evaluate structures to determine the existence and location of surface and interior flaws. The goal of this research was to determine if laser ultrasonic techniques can be applied to the inspection of aluminum plate. titanium tubes, and large welded plate structures. The research...
This research evaluated the ethics competencies which were
determined to be important to the curriculum of an ethics course for
students studying Nondestructive Testing and Welding Inspection. Data
were gathered from samples of American Society of Nondestructive
Testing Nationally Certified Level III's (N = 268), American Welding
Society Nationally Certified...
Capacitor discharge welding (CDW) is a rapid solidification joining process under
the influence of one-dimensional thermal gradients. Although CDW is useful for joining
small parts and dissimilar metals, CD welded joints have a large variability in weld
strength. CDW is not widely accepted because of a lack of automated process...
