Carr’s jump into 6 axis Laser welding

Carr’s welding has been Laser welding since 1998, and has always invested in the latest and the best equipment.  Using Yag lasers to clad components, to repair tools and recover worn parts is what Carr’s do every day.  Their latest Laser moves into new territory.

The Trumpf 1006D Laser, welds steel and titanium at a fantastic rate, and can fuse joints and seams with a precision key-hole weld.  The 6 axis robotic arm, delivers the laser to 3D assemblies with the accuracy and repeatability that can never be achieved manually.  An assembly can be jigged and once the Robot Laser is programmed, can be welded in seconds, giving a small unit cost.

Batch sizes can be small with minimal scrap rates, but the beauty of Laser welding is that the condition of the weld is so neat that there is often no after welding operation or fettling.  Good fit up is essential however, so no gaps can be left for the small Laser spot to disappear down.  Joint design which favours the Lasers should be discussed at an early stage.  Filler wires are not normally added when running at high weld rates, so excess material can be left on the joint design if “proud of flush” welds are required.
