Standards for the production of medical equipment

Medical products require the highest level of precision. They must satisfy the highest standards of quality. The sizes of many medical equipment and products are constantly shrinking. Lasers can be found since they're perfectly suited for the creation of equally small welding seams. Even in difficult locations, laser welding marks and seams can be created to create clean surfaces without any post-processing.

Medical laser welding has many benefits

Because laser welding is non-contact, the surrounding material suffers little or no heat damage. This is beneficial to the medical business because it is the most efficient and non-intrusive method of welding medical tools. If you want a medical laser welding service you may consult Proto Lase.

As a result, one of their responsibilities is to ensure that no damage occurs. Laser welding is essential in this business since precision is essential. Furthermore, because it is a precise manufacturing method, it is a quick technique to reduce economic spending. It also ensures that output is of high quality and quantity.

The superior weld integrity that can be that is achieved by laser-welded joints is what makes them suitable for high-temperature sterilization. In addition, the smaller affected area guarantees that the surrounding materials are not being annealed or weakened. 

There are a variety of metals that are laser-welded including alloys, and there are no filler materials used during the process. This means that there are no biocompatibility issues with implant-related products.

What is its use in the medical field?

Some types of medical equipment that could be made with the help of laser welding are:

• Pacemakers

• Hearing Aids

• Prosthetics

• Catheters

• Defibrillators

It can be difficult to identify the cause of a process error and adjust it to minimize it. This is because many physical tests need to be performed in addition to the destructive tests.

An alternative way to iterate on process parameters is to use high fidelity numerical modeling, and transfer many of the process design studies to a simulated environment.

Technologies like simulation and digital twins are important technologies for the movement of NDT 4.0 (non-destructive testing).

Most numerical modeling of laser welding and additive manufacturing processes is done with FEA approaches (“Finite Element Analysis”) looking at thermal stresses, distortion, and cracking. 

These types of models inform a part-scale analysis and are useful for doing big-picture parametric studies. However, there are few tools available for doing micro-and mesoscale analysis of melt pool dynamics which require high fidelity models including fluid flow, heat transfer, phase change, and laser-material interactions as they relate to laser setting such as power, distribution, speed, and scan paths, as well as additional physics such as laser reflections and shield gas effects.

FLOW-3D WELD has been uniquely designed to accurately model the melt pool dynamics at the micro and meso scales which gives insights into process dynamics that are difficult, if not impossible, to capture with conventional experimentation.
