Minimizing wall thickness variation in seamless tubing

August 28, 2003

By:

All mechanical steel tubing has some amount of wall thickness variation. Wall variation in welded tubing results from the strip manufacturing and tube welding processes. Seamless tube, which is created from a hot billet of solid steel, has wall variation that results from tooling wear, bearing and shaft variation, and normal hot-process variation. The wall thickness in seamless tubing varies in the cross section and along the tube's length.

Considering thermal processes for dissimilar metals

August 28, 2003

By:

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.
