Laser Welded Plate Technology Overview

Laser Welding Principles

Laser welded plate technology relies on the laser welding process to join metal plates with high accuracy. A focused laser beam delivers intense energy to a small area, melting and fusing the plate surfaces together. This method stands apart from traditional welding because it uses less heat and achieves deeper penetration. The laser welding system operates at high speed, which increases productivity and reduces energy consumption.

Key principles of laser welding include:

• High energy density: The focused laser beam concentrates power, allowing for fast and deep welds with minimal energy loss.

• Low heat input: The laser welding process creates a small heat-affected zone, which limits distortion and preserves the plate’s properties.

• Pinpoint precision: The laser welding system can produce intricate welds in tight spaces, making it ideal for complex plate designs.

• High speed: Laser welding applications complete tasks much faster than conventional methods.

Several types of lasers are used in plate construction. Fiber lasers offer high efficiency and excellent beam quality, making them the industry standard for most laser welded plate projects. Disk lasers provide similar benefits, delivering high power and good beam quality. Nd:YAG lasers excel in spot welding and micro-welding, while CO₂ lasers work well for non-metals and thick metals. Diode lasers are compact and energy-efficient, suitable for conduction mode welding.

Industry leaders like Shanghai Plate Heat Exchanger, heattransfer, and the Wide Gap Welded Plate Heat Exchanger have advanced the use of laser welding systems. Their innovations set new benchmarks for reliability and performance in laser welded plate technology.

Tip: Laser welded plate technology reduces thermal distortion and improves weld quality, making it a preferred choice for high-precision manufacturing.

Plate Construction and Materials

The construction of a laser welded plate depends on the choice of material and the design of the plate itself. Manufacturers select materials that offer durability, corrosion resistance, and optimal thermal performance. The laser welding system ensures that each plate receives a clean, strong weld, which is essential for demanding industrial environments.

Common materials used in laser welded plate construction include:

The choice of plate material affects the durability and performance of laser welded plate heat exchangers.
