Laser welding machine is a laser beam fusion material with extremely high energy density. It has the advantages of fast welding speed, high strength, narrow weld, small heat affected zone, small workpiece deformation, less subsequent processing workload, and high flexibility. The laser welding machine can not only weld common carbon steel and stainless steel, but also weld materials that are difficult to weld by traditional welding, such as structural steel, aluminum, copper and other metals, and can weld various types of welds.
Modern stainless steel bathroom manufacturing has higher and higher requirements for welding strength and appearance effect, especially for parts with high added value and high requirements for welding quality, which can be completed without or with little follow-up processing. The traditional welding method, due to the huge heat input, will inevitably bring about the distortion of the workpiece and other problems. In order to make up for the problem of workpiece deformation, a large number of follow-up processing means are needed, thus increasing the cost.
We have created a laser welding machine with minimum heat input and minimal heat affected zone, which can significantly improve the quality of welding products and reduce the time of follow-up work. In addition, the welding efficiency and stability can be greatly improved due to the high welding speed and large welding depth to width ratio. Therefore, laser welding machine is more and more widely used in the manufacturing of bathroom, stainless steel, glasses, mobile power supply and other industries. Due to the extremely low heat input during laser welding, the deformation after welding is very small, and the very beautiful welding surface effect can be obtained, and the subsequent welding treatment is very few, which can greatly reduce or cancel the huge labor costs in polishing and leveling processes. Laser welding machine is carried out in a closed safety hood and equipped with an automatic dust extraction device, which can not only ensure the health and safety of employees, but also maintain a clean and tidy working environment in the plant.
Compared with traditional welding, laser welding machine has obvious advantages, but the laser welding machine also has higher requirements on the former processing accuracy of the workpiece and the fixture. To maximize the advantages of laser welding, reduce production costs and provide production efficiency, it is necessary to optimize the entire stainless steel production process such as product design, laser cutting, stamping, bending and laser welding. Through investigation, we found that the process of laser welding stainless steel products is not the main cost factor. Actual production experience has proved that 70% of the cost of stainless steel products is determined by product design. To reduce production costs and improve welding efficiency, we need to start with product design. In the initial product design, the requirements of the laser welding machine on the workpiece should be taken into account, such as reducing the bending process in production, using laser cutting plate as much as possible, and using self-localization design, etc., which will make the laser welding procedure and fixture very simple, thus achieving the goal of reducing costs and improving efficiency.
Laser welding machines have been used in the bathroom industry for many years. With the continuous progress of control technology and laser technology in recent years, the use of laser welding machines has become more and more simple and easy. How to give full play to the advantages of laser welding machine in the production of stainless steel sanitary products needs to have a global perspective and optimize the entire product manufacturing process. Adopting friendly design suitable for laser welding will be the key to obtain beautiful welding surface effect, improve production efficiency and reduce production costs.
