Laser Welding in Medicine

Carrs have been laser welding surgical instruments and orthopaedic implants for nearly 10 years. Titanium and high grade stainless steel, key materials for in the medical field, are welded best with laser rather than conventional means. Laser welding has a reduced heat input, decreasing risk of distortion and alteration to essential properties of the material.

Precision welding coupled with 100% inspection and a nil failure record makes laser welding the clear choice in the medical industry.

3D Chromatograpy

This large sieve is part a larger chromatography machine for a pharmaceutical product. The mesh had to be sealed to the outer ring and around the fixing holes, so to minimise the ingress of the product into areas that cannot be flushed clean. The ring is made of a sandwich of steel plates with the mesh in the middle. The 1mm plate on the top is stake welded all through the mesh and into the 6mm plate underneath. This techniquesecures the mesh and keeps it tort across

Ball Assemblies

These stainless assemblies are made from 3 parts and the wire is welded to the base and the ball with a neat laser weld. They are polished after welding as no bug traps are allowed. They are a consumable device being discarded after use.

Wrist Implants

This implant is fitted with a small rare earth magnet, which is encapsulated in the device. Laser welding is used to melt in the lid, but the magnet has a maximum temperature allowed of 110C, which must not be reached otherwise the magnet loses its properties. The welding is hot enough to melt stainless steel at 1440C but must not reach 110 degrees only millimetres away. The magnet triggers a proximity sensor when in the correct position. Laser welding is perfect for this job

Catheter Cutter

This cutter is used to prepare a catheter from a solid tube. Laser welding blades to a straight wire allows the wire to pass through the tube and the blades cut a section from the tube. This produces the precise cut out needed for the diagnostic catheter required

Laser Welding 3 Peak Challenge in June

Laser welding

Carrs swap their activities from Laser Welding to the ‘Three Peaks Challenge’ which involves climbing the three highest peaks of Scotland, England and Wales. Alistair, John and Tom will attempt to cover the total walking distance of 23 miles (37km), a total ascent of 3064 metres (10,052ft) – and a driving distance of 462 miles. […]
