Complete solution for laser welding roof seams
For gap-free laser welded joints and high-quality laser weld seams
The complete WeldMaster Pressure Wheel solution is a combination of laser welding optics and an adaptive, mobile pressure wheel - designed for precise, process-stable welded joints in modern series production. It optimizes overlap and fillet weld joints through targeted gap closure between the upper and lower sheets, thereby supporting the production of dense, high-quality weld seams.
The technology enables camera-based, upstream control of the welding position. This allows parameters to be adjusted online in the event of changing welding conditions - for maximum process stability and repeat accuracy.

Targeted gap closure supports tight laser welding seams
constant contact pressure, independent of component position
The pressure roller ensures a constant contact pressure on the joining geometry - even when the position changes. Unevenness and thermally induced stresses in the component are reliably compensated for. This achieves uniform process conditions for stable weld seams - ideal for large free-form geometries.
Seam tracking & inspection in real time
The camera-based WeldMaster system continuously detects the joining geometry and positions the laser precisely and independently of the pressure roller. At the same time, the online inspection records the seam geometry and detects possible welding defects - in real time.
Adaptive process control for maximum flexibility
Two independently controllable laser channels allow dynamic power distribution - e.g. for lasers with core-ring geometry. This gives you flexibility for demanding processes or changing workpiece pairings within a product - with complete control over the process.
