Laser Welding

WHAT IS IT?

Laser beam welding machines use either a Continuous Wave (CW) laser or a pulsed laser to join materials. This method produces an exceptionally robust and durable seam, which makes it perfect for industrial manufacturing.

Many industries choose this approach for bottom-line cost savings and improved efficiency, including:

  • Automotive
  • Medical
  • Jewelry-making
  • Battery manufacturing
HOW DOES IT WORK?

Laser beam welding works by introducing continuous heat to the joint between two workpieces using a high-power density beam. The heat melts the material, which resolidifies as it cools. During the process, the beam touches only the surface, preventing damage to underlying materials.

Various fiber laser welding methods exist, generally falling into two categories — deep penetration and heat-conductive welding.

Deep-penetration welding is also known as keyhole welding. This approach is ideal for narrow and deep welds and limits the area impacted by the laser’s heat. Heat-conduction welding produces visually pleasing results with a smooth seam that typically requires no extra finishing. As a result, it’s best for shallower joints.

Most industrial laser welding machines contain automated systems delivering inert gases to the area to avoid oxidizing the material. Options include argon, nitrogen and helium.

WHAT IS THE PROCESS?

Overlap, edge-flange, filler-lap and butt welds are common joints used in laser welding systems by manufacturers. Each relies on certain process elements for success.

Targeted Heat

Because laser welding depends on achieving a material’s molten state, a concentrated heat source is required — in this case, a high-powered laser. The resulting melted material forms a solid joint as it cools, often without needing an additional filler.

High Speeds

Laser welding is compatible with advanced technology, such as robotics. Integrating these automation solutions into your facility’s production strategies promotes efficiency and accuracy. In practice, an industrial laser welding machine can cover meters of material in just minutes. The faster processing results in higher throughput and component consistency.

Extreme Versatility

This welding approach is ideal for processing workpieces that lend themselves poorly to traditional table welding. It’s also suitable for delicate and many challenging-to-weld applications. However, manufacturers most often choose laser welding with titanium, stainless steel and mid-steel materials.
