Laser Welders: How They Work, What They Can Do [With Videos]

Laser welding may seem like a new technology, but it has actually been used in many industries for more than 20 years. While it is a proven technology like Tig and Mig welding, it's not as commonly used; therefore, there are many questions surrounding laser welders, including how they work, the benefits of laser welding, and its capabilities.

How Laser Welding Works

Laser welding is a high-precision welding technique that uses a focused laser beam to join pieces of metal together. The laser provides a concentrated heat source, allowing for narrow, deep welds and high welding speeds.

During the laser welding process, a high-powered laser is directed onto the materials to be joined. The intense energy from the laser melts the materials at the joint, which then solidifies to form a strong weld. Depending on the application, laser welding can be done with or without filler material.

Benefits of Laser Welding

There are many benefits of laser welding:

·      Laser welders can weld a variety of metals, including stainless steel, carbon steel, aluminum, galvanized steel, and copper

·      4x faster weld speeds compared to traditional welders

·      Increased weld strength

·      Decreased porosity

·      A clean, uniform weld bead that needs minimal post-processing

·      Easy-to-use system that requires less training

Because laser welders use a laser beam, these units do have specific safety requirements. Manufacturers considering laser welding should contact a knowledgeable laser welder expert about specific safety requirements.

Capabilities of a DNE Handheld Laser Welder

There are several handheld laser welders available, each with different capabilities and strengths. The DNE Handheld Laser Welder has many capabilities that make it a good option for manufacturers; companies should consider a DNE Handheld Laser Welder expert to find out if and how the DNE laser welder can benefit their business.

Large Arced Welds

With a 20μ spot size, the DNE HW series minimizes heat-affected zones, weld deformation, and burn-through. DNE's laser welding process yields clean, uniform weld beads that necessitate minimal post-processing---including parts with a long seam.

Stainless Steel Tubes

The DNE Handheld Welder can weld a variety of materials(i.e. stainless steel, carbon steel, aluminum, galvanized steel, etc.) and parts with different shapes, including tubes.

Wobble Welding

Capable of wobble welding up to 4 mm, the DNE Handheld Welder can fuse materials together, with or without a wire.

Dual Wire Fillet on 0.25" Plate

The DNE Handheld Laser Welder can achieve a dual wire fillet on a .25" plate.

Passivate

The DNE Handheld Laser can remove contaminates with ease.

Conclusion
