what kind of Welding is there in the roll forming machine? 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. though many welding technologies use on tube and pipe mills, three have come to the front:
