It is also a lot more flexible, allowing the user to modify hole size, shape, and approach angle while maintaining repeatability and quality. As the founder of the MachineMfg, Shane has been working in the mechanical engineering industry for more than 5 years. He loves writing and focuses on sharing technical information, guidance, detailed solutions and thoughts related to metals and metalworking.
For example, a laser can have 300 W average power and 6000 W peak power. These lasers are often referred to as Quasi Continuous Wave Fiber Lasers. As the name states, the Continuous Wave lasers deliver a continuous, uninterrupted output. This output can have an upslope (soft-start) when switched on, an energy modulation while active, and a downslope when switched off . Of course, this type of laser can also be switched on and off to create pulses.
In practical applications, the height of the focus varies with the material and the cutting machine. This video displays the working process of our 2000W automated laser welding machine. This large format custom laser welding machine can be tailored to your exact requirements. Thanks to its larger working area, much bigger parts can be processed. Fiber laser welding machines have greater flexibility for non-contact long-distance welding of hard-to-access parts. Additionally,according to our market data,there is almost no customers to cut pipes by Plasma cutting machine,cause for pipe cutting, it need a higher precision than metal plate cut,so its hard to the Plasma cutting machine.
We serve a variety of manufacturing industries with direct part marking solutions. A new area of application in recent years is the oil screen seam pipe. Copper and brass are cut only when there is a “reflective absorption” device installed on the system, otherwise, the reflection will destroy the optical components. On the other hand, the molten oxide and the melt are blown out of the reaction area, forming an incision in the metal. Air can be supplied directly from the air compressor, so it is very cheap compared to other gases.
Just missed a little section about piercing but still this is the best there is!! In the field of automobile manufacturing, the cutting technology of space curves such as car roof windows has been widely used. Secondly, lasers can cut nonmetals, while other hot cutting methods cannot. It is convenient to combine with automation equipment, and it is easy to automate the cutting process. The auxiliary gas entering the nozzle can also cool the focus lens, prevent the dust from entering the lens seat to contaminate the lens and cause the lens to overheat.
Laser cutting forming technology also has a wide range of applications in the field of non-metallic materials. The cutting quality of the laser cutting machine is an important standard to judge whether the cutting machine is qualified. Compared with oxyacetylene cutting and plasma cutting, there are many kinds of laser cutting materials, including metal, non-metal, metal base and non-metal matrix composites, leather, wood and fiber. However, for different materials, due to their own thermal physical properties and different absorption rate of the laser, they will have different laser cutting adaptability.
（2）Various special cutting systems, material conveying systems, linear motor drive systems are been developed in order to improve production efficiency. In order to prevent the sediment from entering the pump, a uniform slit of 0.3mm wide was cut on the alloy steel tube with a thickness of 6~9mm. The cutting technology is difficult, but there are still many factories adopt this method and put into production. The most widely used typical parts are the die-cutting plate used in the packaging and printing industry. It requires a slot with a width of 0.7-0.8mm on a wooden plate of 20mm thickness and inserts a blade in the slot.
The laser generators and cutting heads are international brands, such as Precitec, Raytools cutting heads, IPG laser source, etc. We also offer economical solutions, such as using Raycus lasers and WSX laser cutting heads made in China. Enjoy both manual laser welding and auto laser welding with one machine. Because process control is more precise, the range of process parameters is wider. The additional control provides even greater capability to laser weld dissimilar materials.
Compared with other thermal cutting methods, laser cutting is characterized by fast cutting speed and high cutting quality. When oxygen is used as a processing gas, the cutting edge is slightly oxidized. For plates with a thickness of up to 4mm, nitrogen can be used as the gas for high-pressure cutting.
Combined with the computer, the whole plate can be arranged to save material. During operation, it is only necessary to change the numerical control program to apply the cutting of different shapes of parts, which can perform two-dimensional cutting and three-dimensional cutting. When cutting plastics such as polypropylene, compressed air is been used.
The comparison of laser cutting, oxyacetylene cutting and plasma cutting methods is shown in Table 1. The cutting material is low carbon steel plate with 6.2mm thickness. Of course, for high-reflectance materials such as gold, silver, copper, and aluminum, they are also good heat transfer conductors, so laser cutting is difficult and can’t even be cut. When the steel is cut, oxygen is used as the auxiliary gas and molten metal to produce exothermic chemical reaction oxidation material, while helping to blow away the slag in the slit. Laser cutting can achieve better cutting quality due to the small laser spot, high energy density and fast cutting speed. It is obvious that using oxygen as an auxiliary gas can achieve high cutting speed compared with the inert gas.
Install it on the die-cutting machine to cut off a variety of printed graphics boxes. Stainless steel used for decoration, advertisement, service industry or patterns, marking and font of non-metallic materials . Such as the pattern of an art photograph album, Chinese and English fonts of the company, government department, the hotel, the shop sign, the station, the pier, the public place. Cutting torch during laser cutting has no contact with the workpiece and no tool wear. The machining of parts with different shapes does not require replacement of the “cutter”. The laser cutting process has low noise, small vibration and no pollution.
