What Types Of Materials Can Be Used In Laser Welding?

If you’re looking for an efficient way to use the application of welding on a minor scale for materials that possess high heat conductivity, such as gold diamond for jewelry or maybe tungsten and aluminum for detailed automobile parts, you should consider laser welding. A laser welding machine is a tool that uses high-powered lasers to weld together objects by striking at high speed and penetrating the material. These machines are often used in the manufacturing and automotive industries to weld together metals that require low heat input. Laser welding machines can vary in size and power, but all function by using a high-powered laser to heat up and melt the materials being joined together. This process creates a strong bond between the two objects, making it ideal for applications where durability and strength are essential.

While most people are familiar with laser welding, they might not know which material is more suitable for laser welding and how to distinguish them compared to all other materials available. Here is a list of materials that can help you make a better decision when it comes to working on workpiece material through Laser Welding.

Types of Materials Used in Laser Welding

1.Die Steel

Die steels are a special class of steel that is typically used for making tools and dies. They usually have high hardness and wear resistance, making them well suited for applications where cutting or machining tools are needed. Laser welding can provide a high-quality weld on these materials, allowing precise toolmaking capabilities.

2.Carbon Steel

There are several advantages to using a laser welder for carbon steel. First, laser welds are solid and have minimal distortion. This makes them ideal for applications where precision is important, such as in the automotive, aerospace and medical industries. Additionally, laser welds are typically less likely to crack than other welds. Carbon steel is also relatively inexpensive and easy to find, making it a popular choice among welding professionals.

3.Alloy Steel

A laser welding machine can effectively weld alloy steel. Using the correct laser wavelength for the particular type of alloy steel being welded is crucial, as each kind of steel has a different absorption spectrum. However, a laser welding machine can produce a firm weld resistant to corrosion and crack with the correct laser wavelength and settings.

4.Stainless Steel

Laser welding is a very efficient and precise way to weld stainless steel. The laser beam quickly melts the material and creates a strong joint. Additionally, because the laser beam is extremely focused through the application of a lens, it produces less distortion than traditional welding methods, which results in a cleaner, more aesthetically pleasing weld.

5.Copper and copper alloy


Copper and copper alloy are excellent candidates for laser welding because they have relatively high thermal conductivity, which helps distribute the heat evenly across the joint. Additionally, both materials are highly reflective so that the laser beam can be easily directed onto the desired area. However, there are a few considerations when welding these metals. First, copper is a highly conductive metal, absorbing heat quickly. This means that when welding copper, it is essential to use CAM ( Computer Aided Manufacturing) as you will need to adjust the intensity of the laser beam in accordance with the properties of the metal. Additionally, because copper is so conductive, creating a strong weld joint can be challenging. As a result, it’s important to work slowly and carefully when welding copper to avoid mistakes.

6.Aluminum and aluminum alloy

Aluminum has a low melting point and is highly reflective, so it can be challenging to weld. Precautions must be taken to avoid burn-through and porosity. Welding aluminum alloys can be even more challenging, as they often contain impurities that can cause an imbalance in the properties of the metal during the welding process.

It’s also vital to ensure the laser power is appropriately set for the thickness of the welded materials.
