ASTM A513 (Standard Specification for Electric-Resistance-Welded Carbon and Alloy Steel Mechanical Tubing) is a conventional specification that governs tube for many uses, and hydroformers have been relying on tube made to this standard for many years. However, some hydroformers think that some aspects of this specification aren't appropriate for hydroforming: Some portions of it need to be tightened up and others loosened. Developing a modified specification specifically for hydroforming likely will result in less expensive tubing and fewer failures.

The energy sector is hot right now, and so is pipe production. Finding the optimum material for making pipe for this industry is tricky. Low-alloy carbon steels tend to be strong, but lack corrosion resistance. Stainless steels resist corrosion but lack strength. Cladding low-alloy carbon steel with a thin layer of a corrosion-resistant alloy is a suitable process, one that AWS Schaefer has devised for manufacturing such pipes.

Tube traditionally is produced with a constant wall thickness, leaving design engineers stuck with designing tubular parts and unable to optimize them. A tube with variable wall thickness changes all that. This technology allows design engineers to specify the wall thickness in various areas of a tubular component—increasing the wall thickness in bend regions to prevent splitting and decreasing wall thickness elsewhere to reduce part weight.

More than a decade ago, tube hydroforming grew in two directions: low-pressure hydroforming (a patented process) and high-pressure hydroforming. Since then the industry has grown to include all manner of robots, laser cutting systems, punching operations, and so on. Manufacturing consultant Gary Morphy takes us through about two decades of trends and developments and sheds some light on the future of this industry.

Sheet hydroforming has fewer restrictions when forming complicated parts, which gives styling designers and manufacturing engineersmore flexibility during the design process. To provide a stylish body shape for the Pontiac Solstice®, GM chose sheet hydroforming to manufacture its hood, door, deck lid, and body side assemblies.
