Laser welding has become commonplace on many medical, light industrial, sensor and telecommunication products. Northeast Laser provides a variety of laser joining services, including seam and spot welding on both curved and flat surfaces. Northeast Laser utilizes both manual and automated Nd:YAG workstations.

Our manual laser welders with fixed optics are capable of delivering exacting pulse energy between 0.5 to 120 Joules/pulse. These weld stations are utilized in spot welding of very small to medium size assemblies, wire joining, seam welding of low quantity or prototype runs (where hard tooling is often unavailable), and pre-tacking of assemblies to reduce set-up time at automated weld stations. Beam spot diameter and pulse length is fully adjustable to accommodate everything from the most delicate application to 0.040” penetration.

Our CNC automated weld stations, with fiber optic beam delivery, are capable of handling small to large order quantities, with precise part positioning and weld placement. Northeast Laser has lathe-type and (up to) 5-axis positioning workstations to handle both simple and complex weld paths. With laser power supplies of up to 250 watts, Northeast Laser is capable of optimizing weld parameters for cost-effective processing of your components. In addition, our experience with laser technologies, joint design, parts handling, motion control, fixture design, metallurgy, production control and quality systems means that your production needs will be met accurately, efficiently and at competitive pricing. We have six engineers on staff that can respond quickly to prototyping, tooling and production requirements.

Northeast Laser fully supports our welding technology with inspection equipment that includes sample sectioning and preparation, helium mass spectrometer leak detection system (with certification to 1 x 10-9 std cc/min), optical comparator, digital microscope with photographic and measurement capabilities, and microscope inspection stations.
