Reducing the programming and teach-time of welding processes

current seam position to the control unit of the robot. Based on the submitted values, the robot can compensate tolerances in Y (lateral displacement along path) and Z (vertical offset along path), without changing the existing programming. The sensor has a very sturdy construction. The optical filter to prevent extraneous light helps to ensure that operations proceed properly when working less than 15mm to the process. Reliable seam tracking is supported by a powerful signal analysis feature, which is especially useful on reflective surfaces. The TH6D uses a state of the art CMOS active pixel sensor to get the most accruable measurements possible. If a welding robot is not used for production it is still possible to lower switching costs with the Scansonic MI GmbHAuto-Guide system. It is an easy- to-use plug and play system consisting of the TH6D sensor in combination with two linear axes. The system is supplied ready to use and all components can a burr-free cut through steel materials. The carbide-tipped saw blades are coated to last longer and it is claimed that, in some cases, they can last four to ten times longer than the average HSS circular saw blade. “Users will quickly see increased sawing performance in their operation,” said Tyler Jantzi, sales director for New- Form Tools. “With advanced coatings, our blades allow for the cleanest,

PROBLEMS can arise when switching a production-line: during the switch production stands still and sometimes it takes even more time to reconfigure and recalibrate than to actually switch the tools. Even after the adjustments are made the user still has to make sure that the change of products fits the quality criteria, which costs time and money. The solution to this problem is online seam-tracking sensors. This kind of optical sensor can automatically detect and compensate variations in the geometry of parts and therefore significantly reduce switching costs. If any common robot is used for welding processes, than a stand-alone sensor like the TH6D from Scansonic MI GmbH can easily be integrated into production. It stores unlimited different welding jobs and in combination with its online detection, switching from one product to another is simple. The sensor uses triangulation for a no-contact scan of the shape of the seam at the joint. It then transmits the NEW-Form Tools has added tungsten carbide tipped (TCT) circular saw blades to its metal cutting product line. Each blade is manufactured to reduce downtime and increase operational speed, and the TCT circular saw blades are specifically designed to address the specifications of the tube and pipe industry. The advanced blades can be used for all kinds of metal cutting, producing
