The double-V seam is also known as an X-seam and double V-joint. It is a type of butt weld and consists of a combination of two V-seams on each of the two sides of the components to be joined. Single butt welds are similar to a bevel joint, but instead of only one side having the beveled edge, both sides of the weld joint are beveled.
Calculating Weld Volume and Weight - TWICalculating the volume of a weld is one of the first steps to be taken when estimating the cost of making a weld. With this information, and knowing the deposition rate of the process, it is possible to determine the arc time (the length of time that an arc is burning and depositing weld metal) and the amount of welding consumables required to fill the joint.

Difference between ERW, DOM and Seamless Tube Metal May 12, 2015 · This month we take a hard look at the differences between ERW, DOM and Seamless Tube. ERW (Electric Resistance Welded) The nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The steel strip
Evaluating Tube Bending Costs Winton MachineThe science seems clear. An eddy current probe would send a signal back to a control box that would then unravel the signal and determine if a weld seam were present. The process involves rotating a tube along its long axis; as an eddy current probe
Figure 1 A tube formed round has a weld seam at the 12:00 oclock location (far left). A subsequent operation on the mill turns this form into a square and leaves the weld seam in the same location. Depending on the roll tooling setup, the weld seam ends up
Quality control and assurance in fabrication of welded Jun 28, 2017 · The current paper presents a comprehensive overview of weld quality control and assurance of welded structures where the major failure prevention is due to fatigue loading. It gives the drawbacks and limitation of quality control systems, international weld quality standards, and guidelines used in todays weld production. Furthermore, in recent development in quality control and assurance
Quality inspections - The FabricatorThe welding fabrication drawing or blueprint provides weld sizes and other welding dimensional requirements such as length and location. These dimensional requirements are established through design calculations or are taken from proven designs that meet the performance requirements of the welded connection.
Controlled by a Windows computer, Wintons RD30 tube bender has a history of standing the production test of time. The machine shown automatically loads material from a hopper, the weld seam is automatically located and the blank is presented to the bender. The carriage moves forward and the collet closes.
Servo-electric bending machine - RD30 - Winton Machine Controlled by a Windows computer, Wintons RD30 tube bender has a history of standing the production test of time. The machine shown automatically loads material from a hopper, the weld seam is automatically located and the blank is presented to the bender. The carriage moves forward and the collet closes.
Shopping cart manufacturer rings up productivity gains The weld seam is harder than the parent material, so whether the seam is subjected to tension or compression, its not likely to withstand the stress. Preventing this is a matter of finding the weld seam and rotating the tube so the weld seam is aligned with the neutral axis. One of Technibilts early weld seam detectors was a mechanical
Weld chatter is the inability to achieve a clean cut of the outside weld bead after welding. The scarf knife chatters and produces a ribbed or rough cut on the OD of the tube. This is unacceptable in most of the end products produced by the tube and pipe industry.
