Choosing a welding process for tubular profiles

TPJ April/May 2015 Issue Cover

Roll formers that want to branch out to welded profiles need to know about the main welding processes – GTAW, laser, and induction. This article compares and contrasts each process so roll formers can determine which is best for particular applications.

Welded profile applications have been steadily increasing over the last 10 to 15 years, driven mainly by the automotive industry. As they look for ways to increase strength and reduce weight, automobile engineers continually research materials and forming processes to find the best combinations of part design, weight, and strength. To get a piece of this growing pie, roll formers need to consider manufacturability and reliability. How easy or difficult will it be to manufacture this profile? How stiff and strong will it be? Will the product be consistent from one run to the next and one day to the next?

Although most roll formed products don’t need welds, the market for welded profiles has been growing for more than a decade. Matching the welding process to the profile is a necessary early step in planning and developing a line for the forming and welding process. Photo courtesy of TRUMPF Inc.

Measuring weld heat to evaluate weld integrity

Thermography digs deep to look for weld flaws

Eddy current and ultrasonic testing are suitable for tube and pipe mills and have been used for weld seam flaw detection for decades, but a new process, thermography, is an alternative. By measuring the heat signature of the weld seam as it cools, it provides information about weld integrity at and below the surface.

A normal welding temperature display shows a band of high temperature at the center, in yellow, flanked by orange, red, and blue as the temperature falls (top). A wide band dominated by yellow indicates too much heat (middle). A dark, narrow band indicates a cold weld (bottom).
