Laser with its high energy and material action to achieve processing effect, laser beam is the most easy to realize the application of metal materials, is also the most mature development and application of the market, mainly including general iron plate, carbon steel, stainless steel, copper, aluminum alloy and so on. Iron plate, carbon steel is more used as metal frame parts, such as automobiles, construction machinery components, transportation pipes, etc., need higher power cutting and welding. And stainless steel is common in bathroom, kitchenware, cutting tools, thickness requirements are not high, medium power laser enough to meet.
China’s housing and various infrastructure projects have developed rapidly, and a large number of construction materials are used. For example, China uses half of the world’s cement, and is the country that uses the most steel. Building materials can be regarded as one of the pillar industries of China’s economy. Building materials need to use a lot of processing, so laser technology in building materials can have what applications? At present, hydraulic shear or grinder is mainly used for the bar and bar of building foundation or structure. At present, laser is more used in pipes and doors and Windows.
Laser processing of metal pipeline building materials pipeline used for water pipeline, gas/natural gas pipeline, sewage pipeline, fence pipeline, metal galvanized steel pipe and stainless steel pipe. With the expectation of strength and beauty of pipe in construction industry, the requirement of pipe cutting has also been improved. Generally, the original pipe forming factory is often 10 meters, or even 20 meters in length. After it is lowered to all walks of life, because of the different application scenarios, it needs 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, very suitable for all kinds of metal pipe cutting, has the characteristics of high automation, high efficiency, high yield. Building materials metal tube thickness is generally less than 3mm, 1000 watts of laser power is enough to cut, using more than 3000 watts of power can achieve high-speed cutting. In the past, it took about 20 seconds for the grinding wheel cutter to cut a piece of stainless steel pipe, but it only takes 2 seconds for laser cutting, which greatly improves the efficiency. Therefore, in the past four to five years, laser cutting equipment has replaced a lot of traditional mechanical knife cutting.
The emergence of the pipe laser cutting process, can put the traditional sawing, punching, drilling and other processes in a machine automatically complete, can cut the pipe, hole, contour cutting and pattern character cutting, pipe laser cutting process only need to input the required specifications into the computer, the equipment can automatically, quickly, high efficiency to complete the cutting task. Automatic feeding, clamping, rotation, groove cutting, suitable for round pipe, square pipe, flat pipe, etc. Laser cutting almost meets all the requirements of pipe cutting, to achieve an efficient processing mode.
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 doors and Windows industry, with the door and window production cost increasing year by year, people also put forward higher requirements for the processing efficiency and quality of doors and Windows products, doors and Windows, anti-theft nets, railings and other use of a large number of stainless steel, It is mainly steel plate and round tank with thickness below 2mm. High quality cutting, hollowing and pattern cutting of stainless steel plate and round tank can be achieved through laser technology at the opening end. Nowadays, hand-held laser welding is very convenient. It is used for seamless welding of metal parts of doors and Windows. It will no longer appear gaps and solder joints as spot welding does, so that the overall performance of doors and Windows is better and more beautiful.
Doors and Windows, anti-theft net, guardrail annual consumption is very huge, the use of small and medium laser power can achieve cutting, welding. However, since most of these products are customized according to the size of the house and undertaken by small door and window installation stores or decoration companies, the mainstream is still the most traditional grinding wheel cutting, arc welding, flame welding and so on. The space for laser processing to replace traditional technology is very large.
Laser processing of non-metallic building materials possibility: non-metallic building materials, mainly ceramics, stone, glass, these processing mainly grinding wheel, mechanical knife, completely rely on manual operation, manual positioning, cutting will produce large dust, debris, and disturbing noise, great potential harm to the human body, now less and less young people are willing to do. These three kinds of building materials are collapse, rupture possibility, laser processing of glass has been developed, the composition of glass for silicate, quartz, easy to react with laser beam to achieve cutting effect, glass processing has been a lot of discussion. While ceramic and stone, laser cutting is rarely considered at present, need further exploration. Find the right band, the right power of laser, ceramic and stone can also try to cut, and achieve less dust, no noise cutting, I hope there will be domestic enterprises to try to break through in the future.
Laser scene processing exploration: residential construction site, or highway, bridge, track and other infrastructure projects, a lot of materials need to be laid on site construction site, and laser equipment workpiece processing is often limited to the workshop, and then transport the workpiece to the second place application. Therefore, it may be an important direction of laser development in the future to explore how laser equipment can be processed in real time in the application scene.
