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?
