Systems we have delivered in this industry

Tray welding system with an inverted-robot gantry and two L-type positioners 9 m Gantry Inverted-Robot Gantry Tray Welding System Access to every inner and outer seam on trays up to 3,000 × 1,800 × 400 mm, with two L-type positioners alternating. View Details Cover welding system with adjustable fixtures and a laser camera 9 m Synced Slider Cover Welding System with Adjustable Fixtures Fixtures adjust from 200–1,350 mm on the short edge and 500–3,050 mm on the long edge, welding the whole cover family with one set. View Details Dual-cell tank welding system with two gantries and four positioners Twin Cells Dual-Cell Tank Welding System Two robots, two gantries and four positioners; X-Y-Z gantries reach every face of the tank while laser seam tracking follows the joint live. View Details Four-station synchronised slider line with torch-integrated fume extraction 12 m Synced Slider Four-Station Synchronised Slider System A 12-metre slider runs under robot control as a 7th axis; fume extraction is built into the torch, capturing fume at source. View Details Laser-camera dual-station welding cell for corrugated tanks Dual Station Laser-Camera Dual-Station Welding Cell Two hydraulically fixtured positioners alternate; a laser camera locates the weld points on the part and absorbs stack-up tolerances automatically. View Details Transformer side wall welding with an inverted robot on a 20-metre slider 20 m Slider 20-Metre Slider Side Wall Welding Line 20 metres on X and 1,200 mm on Y: several build areas are served by one robot, welding side walls up to 4 metres wide. View Details Robotic welding of tank frames on an inverted column slider 8 m Inverted Column Frame Welding System with an Inverted Column Slider Welding frames up to 6 metres in a single setup; Touch Sense and ARC Sense find dimensional deviations and correct the seam automatically. View Details Fully automatic core stacking station with camera-guided twin cartesian gantries ±0.2 mm Accuracy Fully Automatic Core Stacking Station Twin cartesian gantries stack 0.23–0.30 mm silicon steel laminations to ±0.2 mm with camera-guided referencing. An assembly application, not welding. View Details
