Laser Welding

 

Seam welding

   
The laser is a very consistent process and we have adapted it to cnc control. The low heat input, difficult-to-access locations and its uninterruption by magnetism make it a solution for many metal welding applications. See "Laser welding applications guideline" here.   Seam welding

Spot welding

   
Single pulses of a laser beam can weld thin metals even if they are of dissimilar material. Used on the well known Gillette razor blades, gold chains and lamps filaments this technology is proven to be consistent with minimal distortion.   Spot welding

Glovebox welding

   
Although a seal can be made in any environment, many devices require both the seal and the atmosphere in the device to meet a standard e.g. MIL-STO-883A. Moisture and oxygen must be kept below certain values to prevent condensation and oxidation, therefore packages are vacuum-baked for a predetermined time period and temperature and then transferred to the Nitrogen weld area to be laser welded. Our Pyramid glovebox system has a 250 x 250 x 125mm cnc motion system.   Glovebox welding

Package welding

   
Metal packages with feedthroughs are laser welded e.g. medical devices, fuel cell layers, microwave packages, transducers, heat exchangers and hearing aids. Taking advantage of the low heat input and laser weld integrity makes it the right choice for many applications.   Package welding

Metallography

   
Microkerf Ltd offers a complete solution to all metallographic preparation requirements. Our equipment allows users to reveal a true representation of the microstructure of their materials for microscopic analysis. The Nikon microscope provides digital pictures of weld section and surfaces, establishing weld penetration depths and levels of porosity which can be archived as a JPEG. Having this facility in-house allows us to get information quickly and to make improvements to our process parameters efficiency.   Metallography
