Why Laser Welding Is the Gold Standard for Precision and Strength

Laser welding is used in many different industries, typically for the precision it affords. Few industries require the precision of the aerospace industry, for example. Virtually no tolerance variation is acceptable. Cracks, distortions, and material damage can quickly result in aircraft failure.

The high-strength, lightweight alloys used today make welding difficult. Laser welding offers solutions for some of the most challenging applications.

Laser Welding

The pursuit of ‘straight without weight’ is a never-ending goal in some industries. Engineers create designs where multiple materials, such as aluminum, titanium, and steel help reach the goal. Laser welding is used to join these materials with a high-strength bond.

Automated parts vary widely in size. Laser welding is used for everything from large panels and support pieces to small engine components and device housings and can be adjusted for deep penetration and mechanically strong welds or narrow hermetic seals. They use less energy and resources than traditional welding.

Benefits of Laser Welding

Laser welding has many advantages over traditional welding processes. Recent advances make this particular type of welding a viable solution for a wide range of manufacturing requirements. Here are six benefits.

• Consistency. It delivers consistent repeatability. One weld to the next can be virtually indistinguishable.
• Strength. It creates very high-strength welds. Quality, clean processing makes laser welding a favorite for manufacturers.
• Minimal Heat Input. It reduces improper alterations to components. Less heat transfer to the surrounding metal also means less distortion at the weld seam.
• Precision. It is extremely accurate. The laser beams can be easily controlled to weld the tiniest of parts without damaging them. When used with an advanced 3D vision system, welding accuracy is vastly increased, even in high-volume, multi-pass applications.
• Complex Joints. It makes welding together materials that differ from each other possible.
• Speed. It is faster and more versatile than traditional methods. Laser energy provides consistent energy to the weld spot. This means excellent speed, thermal control, and seam quality. Voids and pockets are eliminated and secondary finishing is unnecessary.
