Two widely utilized metal fabrication methods that have been around for decades are laser brazing and laser welding. Both methods use heat to fuse two metal pieces together, although they differ significantly in several important ways. This article will help you decide which method is ideal for your metal fabrication needs. We’ll explore laser brazing vs laser welding in more detail.
Understanding Laser Welding
A focused laser beam is used in laser welding. It is a contemporary method of combining metals to create strong connections between the base metals. Large assemblies experience less distortion. It’s because the laser beam’s high temperatures are concentrated at specific joints.
The welding procedure is famous for uniting different metals because of its accuracy. This makes it particularly suitable for industries. For example, the production of automobiles and electronics.
Laser Welding Benefits Across Industries
Laser welding has become a shining example of precision and durability. This technology’s adaptability is becoming evident as industries change. Let us examine how laser welding shapes and sustains these many fields.
-
Automotive
The automotive sector relies heavily on laser welding. It increases the strength of the components and ensures less distortion of the metal. This is particularly useful for building robust frames for electric vehicles.
-
Electronics
The electronics industry benefits from the accuracy of laser micro-welding. This method works great for joining small parts. Additionally, it ensures that devices like smartphones and wearables. They can maintain their value and durability without compromising design.
-
Shipbuilding
For shipping vessels, the shipbuilding industry requires strong, waterproof seams. Laser welding produces powerful joints. That will satisfy this requirement for strength and safety in the challenging marine environment.
-
Construction
In the realm of construction, structural integrity is essential. Large bases, such as buildings and bridges, combine steel parts using laser welding. This guarantees durability and aesthetic appeal as well.
-
Aerospace
Laser welding satisfies the exacting criteria of the aerospace sector. The technology plays a crucial role in guaranteeing the longevity and durability of planes. It produces lightweight yet strong aircraft components.
-
Healthcare
The medical industry requires accuracy and dependability. Laser welding guarantees functionality and safety. Espcially, while creating complex medical devices, such as implants and surgical tools.
Understanding Laser Brazing
Brazing is a process that sticks two pieces of metal together. It needs to melt another type of metal (like braze, brass, or copper) into the space where they meet. This third metal works like a powerful glue, but brazing isn’t the same thing as laser welding. When you’re brazing, that melted filler gets sucked into the joint through capillary action.
With brazing, you don’t have to line up the parts you’re joining perfectly. Still, you do need to know that brazing works well only when the two main pieces are made out of materials that are essentially the same. If not, it could cause them to corrode where they touch because of galvanic corrosion. So, think of brazing as a way to build a strong connection by adding an extra metal piece into the mix.
Generally speaking, laser welds are more robust than brazed joints. Still, brazing is a valuable technique for joining materials that aren’t the same, such as plastics and metals.
Benefits of Using Filler Materials in Laser Brazing
There are two factors that make it unique in the industry:
Capillary Action: When compared to welding, some people consider brazing’s reliance on filler material to be a drawback. However, this is among its most significant advantages. The capillary action spreads the molten filler material across a larger area and draws it into the joint area. This spread makes the joints more robust and less likely to give way under stress.
Versatility with Temperature: By design, the brazing filler metal does not melt and flow at high temperatures. They are the preferred option when handling heat-sensitive goods because of this characteristic. It’s revolutionary in sectors like electronics, where accuracy is required rather than desirable.
Laser Brazing VS Laser Welding: A Side-by-Side Comparison
In putting metal pieces together, both laser welding and laser brazing are pretty recognized methods. Getting the details and what makes each method unique helps companies pick the best one for what they need to do. Let’s look at them side by side:
-
Process Mechanism
Laser Welding: In this method, you melt and join two metal parts using the strong heat from a laser. When you do deep welding, it makes a connection that’s even tougher than the materials you started with.
Laser Brazing: This method uses a laser to melt a unique material that will stick two base metals together. To be sticked, it does not require melting those metal pieces. When it dries, the bond isn’t as deep as welding, yet the finish is much smoother and looks nicer. Which is an integral factor for jobs where how something looks matters a lot.
-
Material Versatility
Laser Welding: This process requires that the metals be compatible. It works for comparable materials, but some pairs could be complex.
Laser Brazing: When connecting dissimilar metals, laser brazing can be more forgiving. Because it relies more on filler material. By bridging the gaps, the filler increases the flexibility of material combinations.
-
Application Areas
Laser Welding: Preferred for industries where joint strength is critical. It is beneficial for construction, shipbuilding, and the automobile industry. It is perfect for structural applications since it can form strong joints.
Laser Brazing: This is common in the automobile finishing and electronics industries. Where the joint’s aesthetic appeal is as important as its strength. It’s handy for surface attachments and regions that consumers can see.
-
Equipment Investment
Laser Welding: Its sophisticated machinery and related safety equipment need a larger investment. Yet, especially for large-scale industrial applications. It creates durability and the quality of joints can justify this initial expense.
Laser Brazing: Given its surface-level nature and lower safety. It concerns about deep insight heat. The investment can be less intensive than welding. Even if specialized equipment is still required.
Conclusion
When comparing laser brazing vs laser welding, it is evident that each method has distinct benefits. That varies for particular uses.
