Key welding techniques for medical appliions

24/07/2019· Laser beam welding. Laser beam welding is a non-contact process that uses a focused beam of light to melt two pieces together. It features high-power density, a small heat-affected zone (HAZ) and the ability to make spot welds a fraction of a millimeter in width. The technique is also relatively easy to automate and does not require a vacuum

Bundling together quickly and easily. Wires or tubes can be pulled out at any point, and wiring and tubing assely are secure and accurate. With excellent wear resistance and flexibility, it is suitable for acute-angle corners, etc. As it is highly resilient and does not break, it can be used any nuer of times.

Top 5 Types of Spot-Welding Machine (With Diagram)

In spot welding the pressure between the electrodes is still maintained for a short while. Then the electrodes automatically come apart. And this ends the spot welding operation. The sheet or plate should be thoroughly cleaned by an emery paper or steel wire-brush or pickling with sulphuric acid. In spot welding, temperature can reach up to 500°C.

Pro-Fusion: Spot Welding Appliions

If the wires are of small diameter and the spacing between them minimal then the mesh can sometimes be seam welded by clamping the mesh endings together and motioning a welding torch above the weld joint. If the space between the wires is too great then the wires must sometimes be spot welded together.

Induction Heating for Welding Appliions

With induction welding, the heat is electromagnetically induced in the workpiece. The speed and accuracy of induction welding makes it ideal for edge welding of tubes and pipes. In this process, pipes pass an induction coil at high speed. As they do so, their edges are heated, then squeezed together to form a longitudinal weld seam.
