Instructions for use: How to operate the fiber laser welding machine correctly?
Working principle of fiber laser welding machine:
Fiber laser welding machine uses high-energy density laser beam to heat materials. When the material surface is irradiated by the laser beam, it will quickly melt and form a weld seam. The fiber laser welding machine uses a numerical control system to control the size and shape of the weld seam, and has the advantages of high precision, high speed, and no damage. It is widely used in industries such as automotive, electronics, and construction.
Steps to use fiber laser welding machine
1. Choose suitable materials: Fiber laser welding machines can weld materials such as metals, plastics, ceramics, etc. Before using a fiber laser welding machine, it is necessary to select suitable materials according to actual needs.
2. Preparation: Before using the fiber laser welding machine, a safety check is required to ensure that the welding machine has sufficient power and compressed air.
(1) Check for the correct connection before the equipment power cable L is fire wire N zero wire PE is ground wire.
(2) Check whether the inert gas is sufficient and the gas pipeline is intact, and the gas supply valve is opened and ventilated (the gas uses nitrogen / argon, air pressure 0.15Mpa or 0.7Mpa. If not connected, the lens will damage the welding gun head and not be used properly).
(3) Check whether the waterway pipeline is in good condition.
(4) Whether the button or circuit breaker of the laser / circuit breaker is on.
3. Startup sequence：
(1) Turn on the power master switch after checking before use.
(2) Turn the emergency stop button clockwise to bounce up.
(3) Press the chiller start button (the chiller and the system card are charged at the same time, and the display screen is on {Add the coolant and pure water to the water inlet to the standard area for the first time}) Check all water pipes for leaks.
(4) Press the laser start button when the water chiller temperature reaches above 19℃ degree.
(5) Connect safe wire clip to welding plate (if poor contact). The clip, the material and the laser head must be connected to each other to form an electrical circuit for normal welding.
4. Parameter setting: Set the appropriate laser power and welding speed according to the thickness of the welding material and the welding requirements.
5. Welding: Fix the material on the workbench, adjust the position of the laser head, align the laser beam with the welding area, and start the welding program. During the welding process, it is necessary to keep the welding area dry and free of oil stains.
6.Inspection of welds: After welding is completed, the welding area needs to be inspected to ensure that the weld is firm, free of gaps, leaks, and bubbles.
Precautions:
1. When using a fiber laser welding machine, it is necessary to wear protective goggles, gloves, and other protective equipment to prevent the laser from causing harm to the human body.
2. Before welding, the welding area needs to be cleaned and kept dry.
3. When selecting welding materials, it is necessary to choose according to actual needs and avoid using unsuitable materials.
4. When using a fiber laser welding machine, it is necessary to master accurate operating methods to avoid accidents such as equipment damage and personal injury.
