Dynamic Beam Lasers: Expanding the Boundaries of Laser Welding

The Challenge with Traditional Laser Welding

Laser welding already brings speed, precision, and cleanliness compared to traditional welding. But conventional lasers still face limits that slow adoption in heavy manufacturing:

• Weld quality depends on tight tolerances.

• Access to complex joints is difficult.

• Multipass welding on thick sections adds time, cost, and distortion.

These barriers often force manufacturers to rely on older processes or complex workarounds.

Civan’s Dynamic Beam Laser (DBL)

Civan’s DBL adds a new layer of control by shaping and steering the beam in real time. This makes it possible to weld parts and joints that conventional lasers struggle with, while cutting costs and improving consistency.

An Overview of Dynamic Beam Laser Capabilities

Six Core Advantages of DBL

1. Large Focal Plane

• DBL maintains high beam quality across a wide focal plane.

• Engineers can weld from farther away, making it easier to reach tight or difficult areas without special optics.

The large focal plane enables remote welding, so the laser can reach any point within line of sight

2. Welding in 1G, 2G, and 3G Positions

• DBL adapts to the part instead of forcing the part to adapt to the laser.

• Welders can bring the laser to the workpiece, avoiding the need for manipulators or complex fixturing to rotate heavy sections into the flat (1G) position.

• Remote 3G welding of 35 mm thick steel from a distance of 1.5 meters

3. Overcoming Large and Varying Gaps

• Traditional lasers require perfect fit-up. DBL tolerates real-world conditions.

• Example: bridging a 2 mm gap in a 15 mm thick plate without loss of quality.

With Dynamic Beam Shaping, the beam is tailored to fuse the joint walls rather than escape through the gap

4. Single-Pass Thick Section Welding

• DBL can weld up to 35 mm in mild steel in one pass.

• This removes the need for multipass processes that add time, introduce excess heat, and often require flipping the part.

5. Low Heat Input

• The concentrated, fast-moving beam minimizes heat dissipation into the material.

• Results: minimal distortion, smaller heat-affected zones, and less post-processing.

Example: 16 mm stainless steel weld with minimal distortion

6. Easier Pre-Processing

• No beveling required.

• Straight walls from milling or even plasma cutting are sufficient, reducing preparation time and cost.

  
  

Solving the Manufacturing Bottleneck

Manufacturers face a shortage of skilled labor, growing demand, and pressure to reduce costs. DBL addresses this by delivering higher throughput, consistent quality, and easier integration into existing production lines — without relying on complex fixtures or extensive rework.

Dynamic Beam Lasers remove the key barriers that held traditional laser welding back. With large focal planes, flexible welding positions, gap tolerance, and single-pass thick section capability, DBL enables welding and production engineers to simplify processes, cut costs, and expand capacity.
