The laser uses gases to cut . The of the is , the of the gas and the flow rate are .
gases are: air, , , and for steel. The are 99.5% or . The main is to and blow off the cut melt. The and flow rate are for each laser , which is from the size of the and the of the . , the is to be 0.3-0.8Mpa, and the is 0.02-0.05Mpa. The flow rate to the of the . For , when 22mm steel, the flow rate of some must reach 10M3/h ( the for the -layer ).
The laser must use gas in the of . The gas is used in: 1,laser gas (the gas used to the laser in the laser )
2. air ( used to the light path, some also use it as a gas) 3,gas (the gas from the of the as the host said)
gas is used to cut steel. The role is to the and blow off the melt. There are high for the of ( steel above 8mm, which a of 99.999%). The is large, above 1Mpa. If you want to cut steel above 12mm or to 25mm, the is . , above 2Mpa or . The flow to the model of the , but they are all very large. For , 12mm steel 150m3/hfor some , and 3mm, as long as the flow is below 50m3/h.
In terms of cost, used for steel is cheap, and the of used for steel is large, and the of and of steel are to be high and the cost is high.
Among the three gases, air has the cost and is also the of the most . , if the air is not well , it will be to the of the fiber laser , which can cause oily or dirty in the lens of the , which will cause the path of the fiber laser to or fail to cut the . such as wear.
The air from the air a of to clean and dry gas, and into three paths. One part is of high- and high- to form a gas for the head. One part is used as a power to the of the , and the last part is used to purge and dust from the path to the of the laser .
