Composite braze liner for low temperature brazing and high strength materials
An apparatus, material and method for forming a brazing sheet has a composite braze liner layer of low melting point aluminum alloy and 4000 series braze liner. The low melting point layer of the composite braze liner facilitates low temperature brazing and decrease of the diffusion of magnesium from the core into the composite braze liner. The reduction of magnesium diffusion also lowers the formation of associated magnesium oxides at the braze joint interface that are resistant to removal by Nocolok flux, thereby facilitating the formation of good brazing joints through the use of low temperature controlled atmosphere brazing (CAB) and Nocolok flux. The apparatus also enables the production of brazing sheet materials with high strength and good corrosion property.

An apparatus and method for non-destructive evaluation of resistance spot welds uses a line laser triangulation sensor, a linear encoder, and a device for moving the welds relative to the sensor to measure the three-dimensional shape of one or both surfaces of the weld.

The gradient normal of points on the weld surface that are high are indicative of high slope attributable to electrode degradation which can be correlated to weld quality in making the prediction. The apparatus and technique can also be applied to the evaluation of RSR joints.
