This helps at problem areas
Forming longitudinally welded tubes is a constant challenge, as the effect of heat leaves invisible changes in the structure during welding. An electronic sensor system helps to prevent disasters.
Bending longitudinally welded tubes
Finding a weld seam in longitudinally welded tubes or in welded coil material becomes more and more important, especially during automated manufacturing processes, and finally it has an ever-increasing importance for the quality of the final product.
Where is the Weld Seam? Localization made easy!
Manufacturing processes are more automated than ever before. For example, in press lines, the coil material is increasingly welded automatically at the ends. However, it is important that the position of the weld seams is known in the further production - Weld Seam Detection Systems do help!
Safe positioned Weld Seam Detection
Semi-finished products such as tubes form the basis for many intermediate and end products, for example in the automotive industry or in the furniture and heating industry. These tubes are bent, hydroformed and welded.
SND40 in high-performance tube bending cells
The Canadian supplier Deco Automotive has replaced three tube bending lines with three fully automated tube bending lines.
Surveying and documentation of welding seams in the aerospace industry
Components for the aerospace industry must meet high requirements. Welds are particularly critical. In contrast to the design of components for the automotive industry, the tolerances for process fluctuations are far lower so that welds at critical points in particular must be tested extensively.
New sensor detects weld seams at smallest tubes
Roland offers the SND40 Weld Seam Detection System. This was now equipped with a new sensor NS9 EC5x50NT10-100-S. (more in german language)
Full reliability in case of crash
Airbags are a matter of life and death. They must function one hundred percent - that also applies to the individual components, even if it is "only" a welded and repeatedly punched steel tube.
Double Sheet Detection with continuous monitoring
A novel Double Sheet Detection System with appropriately adapted laser sensors enables a seamless monitoring. Double sheets can be monitored for maintenance with maximum process safety. Due to the laser measurement technique, the system is suitable for all opaque materials with a single sheet /…
Weld seam detection on precision steel tubes with a low error rate
The position of a weld seam has a decisive influence on the quality of the end product when bending or hydroforming a tube. An unfavorable seam position causes deviations in the geometry and affects the strength and service life of the component produced.
