Laser Micro Welding

Where precision and quality are the most important factors. This article features the multitude of advantages offered by laser spot welding. We are diving into its superiority over other welding techniques. Finally, we discuss the world of medical products that benefit from this advanced technique.

Automating laser welding on micro scale

It is all about precision, automation and the right components. This innovative technique uses a focused laser beam to create localized welds with great accuracy. When it comes to micro-scale applications, where even the smallest error can be critical, laser shines bright.

Automation plays an important role in ensuring repeatability and consistency. Making it the perfect solution for medical device manufacturers who demand the highest quality in their production. Request a free pre-automation analysis to check if laser welding is suitable for you.

Laser vs. alternative welding techniques: why laser is supreme

While every welding technique has its own advantages, laser spot welding offers several preferences. Especially in the life-science sector. Here’s why it’s the preferred choice:

• Minimal Heat Affected Zones: Laser welding produces minimal heat, reducing the risk of damaging sensitive components. This is crucial when working with medical devices.
• Precision and accuracy: The focused laser beam provides the best precision and accuracy, ensuring that welds are exact and reliable.
• Downscaling: The welds can be made extremely small. With narrow spot sizes this is an ideal process for assemblies that are very small, unusually thin or with complex geometry.
• Control parameters: The wide range of control parameters gives a lot of freedom and space for optimization to define the best process parameters for the weld application. Examples are spot size, wavelength, laser energy, laser type, pulse shape or energy distribution over the spot.
• Non-contact welding: Laser welding is a non-contact process, eliminating the need for physical contact between the welding tool and the workpiece. Alternative techniques require mechanical forces on the product or uses vibrations, which could damage the product.
• No additives: The highest energy can be tuned in the middle of the welded parts to get an ideal weld bath for the best connection. Additive materials are not required.
• Clean and smooth results: Creating clean, aesthetically pleasing welds with minimal splatter. This enhances overall appearance and functionality of medical devices and protects the product for unwanted particles.
• Versatility: Laser spot welding is versatile. manufacturers use it with various materials, such as stainless steel, titanium, copper and even delicate plastics. This makes it suitable for a wide range of applications.

Applications in the medical sector

The medical sector uses micro laser welding to create an array of small products. Some examples of medical devices and components that can benefit from this technology are:

• Surgical Instruments: Used to create durable, sterile, and high-precision instruments.
• Implantable Devices and electronics: These important and delicate devices require hermetic sealing, a task perfectly suited for a laser.
• Surgical disposables: These tools demand precision and reliability. Spot welding is a preferred method for assembly of complicated components.
• Endoscopes: Parts of endoscopes are assembled with laser welding to ensure optimal performance and durability.
• Microfluidic Devices: Manufacturers often fabricate these miniature devices, used for diagnostics and drug delivery, with laser spot welding to achieve leak-free and precise connections.
