Abstract: A bonding tool is adjusted to a desired operational position by viewing the bonding tool with an image-capturing device and displaying an image of the bonding tool as viewed by the image-capturing device onto a display screen. A corresponding image of a reference bonding tool showing the desired operational position of the bonding tool is superimposed onto the display screen and the position of the bonding tool is adjusted with an adjustment mechanism until the bonding tool as viewed by the image-capturing device is aligned with the superimposed image of the reference bonding tool.

Abstract: A composite steel plate includes at least two steel sheets rolled to form a plate. One of the sheets has a composition that varies in a depthwise direction, between nanocrystalline and micron grained. The plate is made by treating a steel sheet to produce a composition in the sheet that varies in a depthwise direction of the sheet between nanocrystalline and micron grained, stacking the treated sheet with at least one other steel sheet, and rolling the stacked sheets to form the plate.

Abstract: A brazing ring with integrated fluxing product and methods for production thereof is described. The brazing ring has a c-shaped body with a plurality of channels extending the thickness of the ring and disposed about the circumference thereof. The channels are separated by radially extending flanges with enlarged distal ends that extend into the channels. The enlarged ends at least partially enclose the channels to aid in retention of a fluxing product disposed in therein. The c-shape may enable flexure of the ring for installation on a pipe or fitting and a friction fit to maintain an installed position. The brazing ring is formed by extruding a filler material to form a tube with the desired profile and compressing the fluxing product into the channels of the profile. The tube is subsequently sectioned perpendicularly to its length to produce a plurality of the brazing rings.
