Diesel Emission Sensor
Inconel alloys are heat- and corrosion-resistant, suitable for service in extreme environments. In this case study, and Inconel 625 alloy tube is laser welded to a machined part made from similar material.

Maxillo Facial Parts
The ease of laser welding two miniature titanium machined parts is shown here.

Tungsten Probes
A very precisely ground profiled tip was ground onto a fine (1mm diameter) tungsten rod.

Crimps
Stainless steel tubes are crimped onto brass pins as part of an electrical connector assembly.

Flow Turbine Tubes
A turbine consisting of 3 stainless steel tubes placed in parallel is made by welding between the end walls of each tube.

Opto Electronics
A miniature nickel-iron-cobalt (Kovar alloy) tube is placed inside a stainless steel tube and the two are laser welded around the tube joint.

Oil Pump Gears
A special micro assembly oil pump requires an effective seal between the outside of the drive cog and the surface of the housing.

Inconel Seal
Inconel is difficult to machine mechanically, but laser cutting with a pico-laser provides a good-quality high precision surface for sealing.

Barbed Tube
A miniature barbed stainless steel tube needs is bent at 90 degrees without damaging the barb or tube. The tube is then placed inside a machined housing and vacuum brazed into place.

Solenoid Coil
A precise distance between two ends of a bobbin assembly was maintained whilst the components were laser welded.

Miniature Tube Assembly
Two miniature stainless steel tubes are seam welded together by laser whilst being held to maintain straightness between the tubes.

Profiled Tube Assembly
Our customer required a housing for a small printed circuit board together with its associated connector.

Laser Cut Probe
A stainless steel tube is laser-cut as an economic first stage in machining and forming a special probe.

Stainless Steel to Nitinol
Photomicrographs show how an interstitial layer of referee material can be used to increase the effectiveness of joining dissimilar materials.

Superelastic Nitinol
A nitinol tube is used in a superelastic stent application, where it expands and contracts at its distal end.

Superelastic Nitinol - Tube Manipulation
A superelastic nitinol needle with a "hooked" end was collapsed and pushed along a stainless steel needle to allow it to penetrate into tissue.
