Product Announcement from Robvon Backing Ring Company, Inc.
Robvon Squings are designed for quick, easy alignment of square or rectangular tubing and to assure a precise, close tolerance fit-up. They allow complete penetration and fusion of the weld.
The patented nubs automatically set the weld gap for the root-pass. The Robvon Squing eliminates the necessity of tack welding and it also eliminates slag, icicles or metal inside of the tube. Squings are available in all the standard materials Robvon offers. Other material available upon request.
