Considering thermal processes for dissimilar metals: Joining steel to aluminum in heat-intensive applications

Knowing how to weld dissimilar metals is becoming more and more important. One reason is that it's often impossible for one material to provide the optimum chemical, physical, and mechanical characteristics needed for an application. For this reason, as well as cost efficiency, technology specialists are experimenting with different joining processes to weld bimetal joints optimally.

Brazing copper tubing: It's simpler than it seems

Torch brazing copper tubing is one of the most common–but widely misunderstood–joining processes. It's possible to make sound joints that are just as strong as the copper tube, easier to braze, and less expensive to produce. But first you have to know basic brazing concepts, including joint design, filler metal behavior, and metallurgy.

Joining metal with adhesives: Advantages, applications, and precautions

Adhesives offer several advantages that make them an attractive alternative to mechanical fastening or thermal joining, such as welding, soldering, and brazing. Advantages include the following: They can be effective on dissimilar metal substrates with dissimilar melting points; they do not cause distortion, discoloration, or weld worms; holes do not need to be drilled into the material in preparation for fasteners; and they distribute stress load evenly over a broad area.
