The Three-in-One Laser Welding Intelligent Quality Control System is an integrated platform that unifies laser welding with dual in-process and penetration-depth inspection in a single automated line. Its defining strength is integrated intelligent inspection — the two detection modules run alongside welding on one unified platform. It combines three functional modules:

Laser welding module: a full range of machine types — robotic welding, automated welding, galvo-scanner welding, precision spot welding and fibre-delivered welding — covers any production scenario, giving the three-in-one system its flexibility.

In-process weld monitoring module: built on a coaxial design principle for high-precision, non-contact measurement. Developed for laser welding process-monitoring scenarios, it forms a serialised product and total solution covering the pre-weld, in-weld and post-weld stages. It monitors laser welding power, height, defects and the entire process in real time, detecting 12 defect types including incomplete fusion, blowholes, spatter and weld misalignment, and flags issues the instant they appear. Process data is stored in real time for individual traceability, strengthening process control and reducing quality incidents.

Weld penetration depth detection module: applies Optical Coherence Tomography (OCT), an optical low-coherence technique that directly measures the depth at the bottom of the molten-pool keyhole, making penetration-depth fluctuation visually evident. Software parameters are optimised with only a few trial workpieces, and the acceptance range is generated directly from product design requirements. Detection precision is high enough to eliminate missed detection while keeping the overkill rate within 1%. When the part or welding requirement changes, only a simple software-parameter adjustment is needed. Beyond a pass/fail verdict, it provides specific penetration values, and all results can be re-verified afterwards to drive quality improvement.

The integrated platform provides single-vendor integration, a unified process-and-quality data stream and reduced equipment footprint, with quality control aligned to the welding process. It is engineered for manufacturers of data centre infrastructure components — liquid cooling manifolds, AI compute cabinet parts and other precision welded assemblies — and adapts readily to adjacent precision welding segments.
