Overview Points

Deep Penetration Welding

1500W Raycus/Chuangxin fiber laser achieves 4mm penetration on stainless steel with leak-proof consistency.

Production Speed Output

Six-axis motion completes 9-column evaporator welding in 42-45 seconds, enabling 2,500 daily units.

Precision Spot Control

0.1mm focused spot via YM52 welding head minimizes heat zones and preserves evaporator dimensions.

Vision Guided Tracking

CCD camera system provides real-time weld seam tracking and compensates for tube alignment variation.

Motion System Reliability

HIWIN ball screws and linear guides maintain repeatable positioning accuracy across extended runs.

Industrial Grade Controls

Schneider contactors and Omron switches deliver robust electrical protection and safety interlocks.

Thermal Stability Control

Mintec chiller maintains 21-25°C water temperature for <3% laser power deviation shift after shift.

Multi Material Capability

Processes stainless steel, carbon steel, aluminum, and copper for diverse evaporator specifications.

Key Features

High-Speed, High-Precision Welding

The six-axis simultaneous motion platform completes a full 9-column evaporator weld cycle in 42–45 seconds. A focused spot diameter of approximately 0.1mm concentrates energy precisely at the joint, producing narrow, deep-penetration welds that minimize thermal distortion on thin-wall tubing and header plates.

Stable 1500W Fiber Laser Output

The Raycus/Chuangxin fiber laser module operates in continuous or modulated mode at up to 5kHz, with output power stability within 3%. Fiber transmission eliminates thermal lensing effects common in conventional laser systems, so focal plane drift does not degrade weld quality during long production runs.

Vision-Guided Positioning

An integrated CCD camera system identifies weld seam locations before the laser fires, compensating for fixture tolerances and part variation. This reduces reject rates on tube-to-header joints where even slight misalignment can cause refrigerant leaks in service.

Industrial-Grade Motion and Electrical Components

HIWIN ball screws and linear guides deliver the positioning repeatability demanded by micro-scale weld joints. Schneider electrical protection devices and Omron limit switches ensure safe, reliable operation in continuous manufacturing environments. Huichuan servo motors with Igus cabling provide responsive, durable axis drive performance.

Controlled Thermal Management

The dedicated Mintec chiller circulates purified water at 21–25°C with flow rates of 16–58 L/min, keeping the laser module within its optimal operating window. Total system power consumption stays at or below 6kW, keeping energy costs proportional to output.
