6000W Laser Cladding Machine

1. Why Is Laser Cladding Important?

Laser cladding is significant because it can be employed to precisely repair, improve, and protect surfaces. It outshines other processes by leaving fewer heat-affected zones, generating less material waste, and being compatible with a variety of materials. Moreover, laser cladding greatly reduces labor costs.

Overall, it’s an effective, economical and environmentally friendly process.

2. Equipment introduction

2.1. Main components configuration list

2.2. Essential parts configuration list

Description: Lasers are precision equipment. In order to ensure the long-term stable and reliable operation of lasers, the operating environment of lasers should meet the requirements of "clean, clean, anti-corrosion, no high concentration of volatile gases, low temperature and low humidity". Therefore, customers need to configure corresponding small air-conditioned rooms according to the on-site environment to avoid condensation in summer and freezing in winter, and prevent dust.

3. Introduction of main equipment

3.1. Laser system (MFSC-6000)

Description: The laser is a precision equipment. In order to ensure the long-term stable and reliable operation of the laser, the operating environment of the laser should meet the requirements of "clean, anti-corrosion, no high concentration of volatile gases, low temperature and low humidity". Since the customer site is located in the southern coastal area, the air is humid all year round. It is recommended that customers configure corresponding small air-conditioned rooms according to the customer site environment to avoid laser condensation and prevent dust.

3.2. Chillers

The precision water cooler designed for laser and optical path cooling of laser processing machine can provide stable and accurate water temperature control for laser, and is the best choice for laser equipment cooling.

3.3. Laser cladding head (ZF-CH003A)

It is a cladding head suitable for medium and high power industrial applications, with diversified interface settings and optimized optical system design, so that it can be equipped with various fiber lasers. The paraxial broadband nozzle is matched to obtain higher cladding efficiency in the cladding process.

Main Parameters

3.4. Double barrel powder feeder

The powder feeding system is an important supporting equipment of the cladding system, and the powder feeding effect directly determines the quality of the cladding layer. The powder feeding system mainly includes four parts: the powder feeder, the transmission pipeline, the powder divider and the nozzle. The powder feeder is the basis of the powder feeding system, which is used to ensure the continuous and uniform conveying of the cladding powder material during the laser cladding process. The unstable feeding component will seriously affect the quality and performance of the cladding layer.

Zhufeng adopts a rotary powder feeder to realize the powder feeding function using advanced aerodynamic principles. We deliver the metal powder that meets the requirements to the working area through precise control of the gas flow and the rotation of the powder plate to meet the requirements of different working scenarios. Widely used in surface treatment processes such as laser cladding with high precision.

3.5. Stabilized power supply

The regulated power supply mainly provides a stable power supply for lasers and machine tools. When the grid voltage fluctuates instantaneously, the regulated power supply can compensate the voltage amplitude in a very short period of time, making it stable within ± 2%. The voltage regulator adopts a well-known domestic peak stabilization brand, and has the most basic protection functions of overvoltage protection, undervoltage protection, phase loss protection, and short-circuit overload protection.

Main Parameters:

Functions and features

1) Over and under voltage protection: when the output voltage exceeds the over and under voltage value of the voltage regulator, the equipment is automatically protected and there is no voltage output;

2) Overcurrent protection: when the current exceeds the rated value, the input is automatically cut off;

3) Limit protection: automatically terminate the adjustment when the brush runs over the area;

4) phase sequence protection: when the phase sequence error or phase loss can automatically protect, no voltage output;

5) Overload and short circuit protection: When the load exceeds the overload capacity or short circuit specified by the equipment, the power supply can be automatically cut off within the specified time;

6) Mains bypass function: when the voltage regulator needs maintenance or failure, the manual switch can be switched in the mains direct state power;

7) Return function: When the sampling voltage is lower than the lower limit reference voltage or higher than the upper limit reference voltage, the brush will automatically return to the center;

8) Power-on mode: with automatic power-on mode;

9) Delay output: After the power is turned on, it will be put into work after an automatic delay of 5-8 seconds;

10) Add true RMS board: high accuracy, good sensitivity, good measurement rate and frequency characteristics. High input impedance, low output impedance, wide power range and low power consumption.

3.6. PLC total control system

1) The control system adopts Siemens PLC controller, which is used to control lasers, powder feeders, chillers and other equipment. Set up a touch screen operation panel to display the operating status and fault type of each equipment in the workstation.

2) Touch screen main console, with alarm information display function, and set the workstation three-color light to indicate the working status, and use the fault sound and light alarm. At the same time, it is provided with pause and emergency stop buttons, which are placed in a prominent position on the control panel. Protective gas, cooling unit and laser are equipped with fault alarm.

4) The control system has a safety protection function. After an emergency stop or collision, the teaching device can be directly operated to start the laser and each axis of the robot without manual release.

5) Electrical control box wires, other cable colors are clearly marked, such as 24V wires only correspond to one color, 220V, 380V and other wires should be different colors, easy to maintain and repair. Bus communication uses standard communication cables. The electrical and electronic devices used by the equipment should comply with IEC international standards.
