The laser interacts with the material with its high energy to achieve the processing effect. The easiest application of the laser beam is the metal material, which is also the most mature market for development and application. It mainly includes general iron plates, carbon steel, stainless steel, copper, aluminum alloys, etc. kind. Iron plates and carbon steel are mostly used as metal structural parts, such as automobiles, construction machinery components, pipelines, etc., which require high-power cutting and welding. Stainless steel is commonly used in bathrooms, kitchen utensils, knives, etc. The thickness requirement is not high, and a medium-power laser is sufficient.

my country's housing and various infrastructure projects are developing rapidly, and various building materials are used in large quantities. For example, my country uses half of the world's cement and is also the country that uses the largest amount of steel. Building materials can be regarded as one of the pillar industries of my country's economy. Building materials require a lot of processing, so what are the applications of laser technology in building materials?

At present, hydraulic shearing or grinding machines are mainly used for rebar and iron bars used in building foundations or structures. At present, lasers are mostly used in pipes, doors and windows.

Laser processing of metal pipes

The upper pipes of building materials are used for water pipes, gas/natural gas pipes, sewage pipes, fence pipes, etc., and the metals include galvanized steel pipes and stainless steel pipes.

With expectations for strength and aesthetics in the construction industry, pipe cutting requirements have increased. Ordinary pipes are usually 10 meters or even 20 meters in length before leaving the factory. After being distributed to various industries, due to different application scenarios, they need to be processed into parts of different shapes and sizes to meet the needs of different industries.

Laser pipe cutting technology has quickly entered the pipe industry. It is very suitable for cutting various metal pipes and has the characteristics of high automation, high efficiency and high output. The thickness of metal pipes for building materials is generally less than 3mm, and the laser power of 1000 watts is sufficient for cutting, and high-speed cutting can be achieved with a power of more than 3000 watts. In the past, it took about 20 seconds for a grinding wheel cutting machine to cut a section of stainless steel pipe, but it only takes 2 seconds for laser cutting, which greatly improves the efficiency. Therefore, in the past four or five years, laser pipe cutting equipment has replaced many traditional mechanical knife cutting.

The emergence of the pipe laser cutting process can automatically complete the traditional sawing, punching, drilling and other processes on one machine, and can cut, open holes, contour cutting and pattern character cutting on the pipe. The pipe laser cutting process only needs to Input the required specifications into the computer, and the equipment can automatically, quickly and efficiently complete the cutting task. Automatic feeding, clamping, rotation, bevel cutting, suitable for round pipes, square pipes, flat pipes, etc. Laser cutting can meet almost all requirements of pipe cutting and realize efficient processing mode.

Door and window application

Doors and windows are an important part of China's real estate construction industry. All houses need doors and windows. Due to the huge demand of the doors and windows industry, with the production cost of doors and windows increasing year by year, people also put forward higher requirements for the processing efficiency and quality of door and window products.

Doors, windows, anti-theft nets, railings, etc. use a lot of stainless steel, mainly steel plates and round cans with a thickness of less than 2mm. At the cutting end, laser technology can realize high-quality cutting, hollowing, and pattern cutting of stainless steel plates and round cans. Nowadays, hand-held laser welding is very convenient. The metal parts used for doors and windows can be seamlessly welded, and there will be no gaps and solder joints like spot welding, making the overall performance of doors and windows better and more beautiful.
