Is the Vee that essential?

Since establishing ourselves, we have built up our skill set and knowledge on ERW tubes so that we can offer customers an unrivalled service that meets all of their specifications. We are confident that our products are consistently high quality and will effectively meet the needs of our clients.

When asked as to what the preferred Vee angle needs to be for tubing materials and sizes, a large number of individuals often draw a blank. However, possessing an understanding of where this angle must be, as well as the gap values existing on it that lead to the apex, can make quite the difference in augmenting production efficiency. Something else that’s critical to your operations is what transpires within the Vee.

Everything that happens inside can influence weld speeds and quality. High frequency current density is at its greatest within the edges that are located close to the apex, as well as the apex itself. Motivating high frequency Vee current flows is dependent on the opening’s angle and the Vee dimensions.

With edges that are parallel, impurities like oxides are mashed out in both directions. In general terms, Vee angles between 2 to 7 degrees are preferable whilst using carbon steel. During the procedure, this angle can swing back and forth, resulting in an alteration of the apex point’s position with respect to the centreline of the weld pressure. These swinging motions could be the result of an inadequate set up, material spring back, or forming rollers that have worn out.

At Union Steel Tubes, there’s no shortage of variety of sizes with our tubing. In fact we have in excess 200 different options. Additionally, thanks to our cutting service, all of our products can be supplied in cut and random lengths too, making the tubing possibilities practically endless.
