Remote Laser Welding

Remote Laser Welding has two major advantages over traditional laser welding with short focal length optics - the high-speed of the intra-weld beam movement contributes to a significant reduction of the cycle time, and the long stand-off of the focusing head permits access to areas not accessible with short focal length welding. W hereas in conventional laser processing the work head is close to the work, with remote laser processing, there is a standoff distance. Consequently, there is the ability to effectively move the beam around with mirrors far more efficiently than if the laser is on a stationary mechanism, such as a robot arm.

 

PECo has over 60 years experience designing and manufacturing proven laser welding systems – an experience base more recently applied to Remote Laser Welders. By integrating state-of-the-art lasers from manufacturers like Rofin-Sinar, IPG and Trumpf, with a large variety of pre-qualified and proven system modules, PECo will design and manufacture the best remote laser welder for your application. PECo’s experienced designers and engineers will also be glad to develop and/or integrate new modules to meet your specific requirements.

 

All PECo laser welding systems are guaranteed for 1 year from system installation.

 

How It Works

Remote laser welding is a relatively new technique based on an old principle where mirrors scan a focused laser beam over the material from a distance of approximately 0.5-1 m for solid-state systems and about 1.5 m for CO 2 systems.

Scanning occurs over an area ranging from a fraction of a square meter to a few square meters, depending on the mirrors being either in a fixed or movable arrangement. The speed with which scanning occurs over the material is in the range of milliseconds per meter, which significantly reduces the in-between-weld repositioning times. This is one of the great cycle time advantages of the remote laser process.

 

The system eliminates dedicated, hard- fixtured, work-holding and tooling. Through program downloading, the remote welders can run multiple part configurations with quick changeovers. The laser can weld various materials, including steels, stainless steels, aluminum and some plated materials, as well as dissimilar materials.
