Need to put a hole in a tube? This article provides an overview of tube punching and tube piercing, exploring the different variations of each method and comparing the two methods on cost, safety, and flexibility.
Eddy current has long been used for inspecting straight seamless or welded tubing. New developments allow the use of this technology to inspect complex tube forms as well.
Editor's Note: This article is the second part of a two-part series about fin passes. Part I discusses their location, what they do, and how they do it. Part II focuses on troubleshooting.
This article explores the facts about AEDs, the legalities surrounding their use by laypersons, and guidelines for implementing an AED program in the workplace.
The secret to developing successful roll tooling—whether for tube production or roll forming—and achieving maximum roll integrity is a simple but often overlooked notion: a comprehensive approach.
The roar of the crowd, the shouts of the umpire, the crack of the bat hitting the ball—these are the unmistakable sounds of a baseball game. Over the last few decades, however, one of those sounds has changed; now the bat tends to make a ping that resonates when it hits the ball. It's the sound of aluminum rather than wood making contact with the ball.
Today's automotive industry is more competitive than ever. To compete with the European, Mexican, and Asian markets, the U.S. market must become more aggressive in finding ways to cut costs.
For hydraulic tube bulging, direct pressure control is the most commonly used process. Pressure control allows engineers to determine the correct capacity hydraulic system and, more importantly, prevent tube rupture. However, inflow control, or control of the volume of fluid inside the tube, theoretically could be another viable hydroforming process. Finite element analysis has shown that inflow control could allow engineers to more accurately predict deformation behavior and therefore enhance the hydroforming process.
