Simple, economical automation of welding joints

Lorch Schweißtechnik, Germany, has introduced an intelligent automation system for circumferential welding, designed for smaller production numbers. Welding automation is generally only considered to be profitable for larger production quantities. With the new automation solution for circumferential welding, Lorch claims to offer an economical system for smaller quantities. The Lorch automation system is very flexible and can easily be integrated into existing systems, with suitability for MIG- MAG, MIG-MAG-pulse or TIG. The system components include the main control unit for all parameter controls, the workpiece

fixture (with torch bracket assembly), and a cold wire feed system, for automated TIG welding. The user is able to select the individual automation system for specific welding tasks. A unique aspect of the Lorch automation system is that the master unit uses LorchNet fully-controlled automatic parameters. It is only necessary to make base adjustments such as workpiece diameter, wire speed and the welding current. Lorch offers this system in four complete packages: the Round 50 Basic system, the complete Round 50 MIG-MAG system, the complete Round 50 TIG system for TIG

applications, and the compete Round 50 TIG-CW system for TIG applications with cold wire feeder. Lorch Schweißtechnik GmbH – Germany Fax : +49 71 91 5 03 297

Modular strip edge trimming It has been established that in the production of welded tubes, the quality of the strip edge influences the standard of welding efficiency and the weld seam. Julius, Germany, provides a modular system for strip edge trimming that allows the flexible use of tools. These modules can be integrated into an existing installation. Welding is easier if the strip edge has an exact width tolerance, a good angle and is clean. The material does not require continuous pressing, and keeps its inner structure at the strip surface. The bulge of the weld seam thus requires less intensive planing of the tube OD/ID. Julius have recently launched the Quinto strip edge trimmer, which consists of 5 modules and a total of 15 tools to machine the edges of wound strips by lifting the swarf. With a hydraulic clamping mechanism, this machine has tools that operate in different modules, distributing any extreme vibration between the various modules. This reduces the oscillation amplitude and enables extreme edge trimming. The company have also recently introduced the Tri-Step System – ideal for wide strips – which is computer operated to line up and adjust the rear tools.
