Xianming Laser Welding Machines – Single-Swing vs Dual-Swing Welding System Technical Guide

As a professional manufacturer of laser welding equipment, Xianming Laser offers two mature solutions for different industry applications and welding conditions: single-swing welding machine and dual-swing welding machine. Both are designed to help customers achieve the optimal balance between welding quality, system stability, and operational efficiency.

System Structure Comparison

Single-Swing Welding Systems

Xianming Laser single-swing welding systems use a single set of high-stability vector scanners to control laser oscillation. The laser forms a linear swing pattern on the workpiece surface.

With a compact and lightweight design, single-swing systems are especially suitable for handheld welding devices or applications that require flexibility and high stability.

Dual-Swing Welding Systems

Xianming Laser dual-swing welding systems feature two sets of high-precision vector scanners, forming a dual-mirror swing structure. The laser beam is reflected by both galvanometers to create a circular or area-shaped oscillating welding pattern on the workpiece.

This design enables more complex and wide welding coverage, making it ideal for applications that demand wide weld seams and consistent weld formation. Dual-swing systems are commonly used in automated welding production lines.

System Stability Advantages

Single-swing welding systems have a simpler structure and fewer internal connections, which significantly reduces potential failure points. This results in higher overall stability during long-term continuous operation.

Dual-swing systems, with their more complex galvanometer structure, offer richer oscillation patterns but require higher precision in system assembly and parameter matching, making them ideal for applications with strict weld consistency requirements.

Ease of Use & User Experience

During setup and daily operation, the single-swing system provides a clear and intuitive red-light indication, making it easy for operators to adjust the red-light center and quickly set welding parameters.

In contrast, the dual-swing system, involving two mirrors, requires synchronized adjustment of the red-light center, which is better suited for professional operators with technical experience.

Welding Performance

Direct Welding (Without Filler Wire)

In non-filler wire applications, the dual-swing system forms wider, more stable weld pools and produces full and uniform weld seams, making it suitable for automated production lines and applications that require high weld consistency.

Filler Wire Welding Applications

For filler wire welding, the single-swing system offers a more concentrated laser spot, stronger penetration, and deeper weld fusion, ensuring stable welding and reliable weld quality.

Maintenance and After-Sales Friendliness

The single-swing system is designed for high disassembly convenience, allowing quick replacement of lenses and fast system adjustments, which reduces maintenance and downtime.

With fewer signals and feedback required, operators can use the Xianming Laser intuitive UI interface to quickly monitor system status, simplifying after-sales maintenance and fault diagnostics.
