How Does Laser Welder With Wire Feed Work?

Laser welding machine is currently a very popular laser equipment in the industrial field. Laser welding machine is not only a tool, but also a key force to promote industrial innovation and development. With the characteristics of high precision, high efficiency and high reliability, it has brought new welding solutions to various industries and reshaped the traditional welding process. Next, we will give a comprehensive introduction to laser welder with wire feed machine, so that everyone can quickly and deeply understand laser welding machine.

1. Working Principle

Use a high-energy-density laser beam to irradiate the joint of the workpiece, so that the material instantly heats up and melts, and a firm connection is achieved after cooling. The core is to highly concentrate the energy of the laser and accurately control the heat input. Through the action of the laser, the molecular structure of the material changes in a short time, thus completing the welding process.

2. Advantages of Laser Welder With Wire Feed

• High-precision Welding: The laser welding machine can achieve extremely small weld width and height, and the welding accuracy can reach the micron level. This makes it have irreplaceable advantages in the fields of precision instrument manufacturing, electronic equipment assembly, etc.
• High-efficiency Production: Laser welding is fast and can complete a large number of welding tasks in a short time. Compared with traditional welding methods, it greatly improves production efficiency and reduces production costs.
• High Welding Quality: The weld of laser welding has high strength and good sealing, and it is not easy to have defects such as pores and cracks. At the same time, laser welding can also achieve high-quality connections between different materials, expanding the application range of materials.
• Environmental Protection and Energy Saving: No harmful substances are produced during laser welding, which is environmentally friendly. Moreover, the energy utilization rate of laser welding is high, which is more energy-saving than traditional welding methods.
• Flexible Operation: The laser welding machine can realize automatic welding through programming, or it can be manually operated to meet different production needs. At the same time, the laser welding machine can also adapt to the welding of workpieces of various complex shapes, with high flexibility.

3. Disadvantages of Laser Welder With Wire Feed

• High Equipment Cost: The price of laser welding machine is relatively high, which may put some economic pressure on some small enterprises.
• High Requirements for Operators: Laser welding machine requires professional personnel to operate and maintain, and the operator needs to have certain optical, mechanical and electronic knowledge. You can buy the laser welding machine produced by Haiwei Laser, which is simple to operate, one hour to get started, and safe and guaranteed.
• Limited Welding Depth: For some thicker materials, the depth of laser welding may be limited, and multi-layer welding or other welding methods need to be used to supplement it.

4. Instructions for Use

• Preparation: Before using the laser welder with wire feed machine, the equipment needs to be inspected and debugged to ensure that the equipment is in normal working condition. At the same time, the welding materials need to be cleaned and processed to remove impurities such as oil and rust on the surface.
• Programming Settings: According to the welding requirements, use the programming software of the laser welding machine to set parameters, including laser power, welding speed, focal length, etc.
• Positioning and Clamping: Place the welding material on the workbench, use the fixture for positioning and clamping to ensure the accuracy and stability of the welding position.
• Start Welding: Press the start button, the laser welder with wire feed machine starts working, and the laser beam shines on the welding material to realize the welding process. During the welding process, it is necessary to pay attention to observe the welding quality and adjust the parameters in time.
• Complete Welding: After the welding is completed, turn off the laser welding machine, take out the welded workpiece, and inspect and process it later.

5. Parameters of Laser Welder With Wire Feed

• Laser Power: Laser power is one of the important parameters of the laser welding machine, which determines the speed and depth of welding. Generally speaking, the greater the laser power, the faster the welding speed and the deeper the depth.
• Welding Speed: Welding speed refers to the speed at which the laser beam moves on the welding material, which affects the quality and efficiency of welding. Too fast welding speed may cause discontinuity of the weld, while too slow welding speed will increase the heat-affected zone and reduce the welding quality.
• Focal Length: Focal length refers to the distance from the focus of the laser beam to the surface of the workpiece after focusing, which affects the accuracy and depth of welding. Too small focal length may cause the weld to be too wide, while too large focal length will reduce the welding power.
• Pulse Width: Pulse width refers to the duration of the laser pulse, which affects the energy distribution and heat input of welding. The shorter the pulse width, the more concentrated the energy and the smaller the heat-affected zone.
• Shielding Gas: Shielding gas can prevent oxidation and contamination of the weld and improve the welding quality. Different shielding gases have different effects on the welding effect. Enterprises need to choose appropriate shielding gas according to welding materials and requirements.

6. Application Fields

• Kitchen and Bathroom Industry: High-precision metal parts welding can be achieved to improve product sealing and durability.
