Medical laser welding is quickly becoming a popular choice for medical device fabrication. Gas shield arc welding (GTAW), which is also called tungsten inert gas (TIG) welding, is currently the most common option for welding medical devices. Laser welding provides several unique advantages.
Decreased Risk of Changes to the Workpiece
Laser welding allows welders to work faster and more accurately on small parts. This results in a smaller heat-affected zone (HAZ).
A smaller HAZ and faster welding minimize the amount of heat absorbed by the workpiece and decreases the risk of changing its composition. Companies that offer laser welding services, such as Micro Weld, Inc, can work on smaller components compared to those that rely on more traditional forms of welding.
Allows Welding of Heat Sensitive Components
As laser welding heats a smaller area, it becomes easier to work with heat-sensitive components. Experienced welders can weld very thin components and parts that may be damaged from extreme heat. Using GTAW welding on the same parts may cause unnecessary damage due to a wider heat zone and deeper penetration.
Automated Laser Welding Is Cost-Effective
Laser welding is traditionally an automated process. However, manual micro laser welding is also available. Automated welding provides the most cost-effective option for high-volume welding applications. If you need to produce a large number of medical devices, laser welding is likely to provide the most affordable option.
The bottom line is that medical laser welding is more practical when it comes to working on medical devices with intricate components. Laser welding offers a level of precision and control not available with other forms of welding.
