IPG Dual-Beam Lasers - Adjustable Mode Beam Technology

Dual-Beam Lasers

Dual Beam Lasers are composed by a core beam and a ring beam.

What Are Dual-Beam Lasers?

Single-beam lasers, the traditional choice for a wide variety of applications, focus one beam of light into a single spot. Dual-beam lasers introduce a secondary ring beam that surrounds the primary core beam. The addition of the ring beam enables a variety of benefits for materials processing applications like welding, cutting, and drilling.

Adjustable Mode Beam (AMB) is the dual-beam technology that powers IPG dual-beam fiber lasers. AMB enables independent adjustment of both the core and ring beams, allowing users to tailor a variety of power combinations best suited to the application.​

AMB dual-beam lasers offer the broadest range of beam profile tunability available, dramatically increasing materials processing speed and quality compared to alternative dual-beam technologies.

Dual-Beam Welding Eliminates Weld Defects

Traditional Single Beam Laser Welding

High-speed keyhole laser welding can create high levels of vapor pressure, propelling liquid metal spatter from the weld pool. Spatter deposition contaminates the work area and increases the risk of short circuits for electrical welding, increasing system downtime and part rework. The loss of material often causes porosity in the solidified joint that leads to reduced strength, cracking, and non-hermetic seams.

AMB Dual-Beam Laser Welding

The introduction of a ring beam stabilizes the weld pool to allow metal vapor to escape without spatter. The addition of this wider area of lower laser power allows the weld pool to solidify more gradually, preventing cracking. By stabilizing the keyhole, AMB enables welding speeds up to more than 10X faster than single beam welding while producing smoother joints with superior mechanical strength.
