              Application introduction

              Galvanized sheet

               

              A large number of galvanized sheet for automotive manufacturing, refrigeration, construction, ventilation

              Heating and furniture manufacturing.

              Zinc plating has become an important method of steel corrosion protection, not only because

              For zinc can form a dense protective layer on the surface of steel, also because zinc has the effect of cathodic protection when galvanized

              In case of damage, it can still prevent the corrosion of iron base metal through cathodic protection.

              Why choose laser equipment to process galvanized sheet?

              From the point of view of auxiliary gas, generally there are three kinds of cutting process for galvanized steel sheet, namely air cutting, oxygen cutting and nitrogen cutting.

              In the process of zinc plating plate, need to add auxiliary gas, auxiliary gas purity and pressure linear impact cutting plate section quality, cutting with oxygen purity should be more than 99.6%, when cutting with oxygen purity is higher, the roughness and quality of cutting galvanized plate section is also higher.

              Nitrogen purity should be more than 99.5% during cutting. The improvement of nitrogen purity can ensure that the color of the cutting seam does not change in the process of cutting galvanized sheet.


              Industrial laser cutting: examples of applications

              What is the point of buying a laser for industrial metal cutting?

              • Precautions

                In general, galvanized sheet can be cut by laser cutting machine, the hardness of the material is the same as the ordinary steel plate material. For zinc-coated sheet cutting, we recommend a more powerful metal laser cutter. Galvanized sheet hardness than copper to a soft grade, metal laser cutting machine can easily complete the cutting of copper, galvanized sheet nature is no problem. Therefore, the laser cutting machine is able to cut galvanized sheet. But here to remind everyone of a, metal laser cutting in order to achieve good process effect, need to use auxiliary gas in laser processing. Metal laser cutting machine available gas oxygen, nitrogen, which is the main metal cutting auxiliary gas. To achieve a certain quality of cutting, we should pay attention to the purity of the gas. Using oxygen cutting should pay attention to the purity of oxygen should be in 99, here to say one more, in the process of cutting galvanized plate, need to add auxiliary gas 99.66 above, nitrogen purity should be in 99.5 above, so that the cutting galvanized plate is able to achieve higher requirements. The role of oxygen is oxidation combustion, the role of nitrogen is antioxidant flame retardant. The zinc-coated sheet cut with nitrogen is not only smooth, but also has no yellow color change.

                • Fast cutting speed and high production efficiency


              Advantages of fiber cutting machine processing galvanized sheet

               

              Fiber laser has the advantages of good beam quality, good monochromaticity, directivity and stability.

              And has the advantages of free regulation, free maintenance, high stability, which is the traditional laser can not be compared.

              Fiber laser can play a better role in high yield aluminum - zinc coated plate and zinc - coated plate.

              Air cutting:

              The advantage is that the processing cost is extremely low. It only needs to consider the electricity cost of the laser itself and the air compressor. It does not need to generate high auxiliary gas cost, but the cutting efficiency on the thin plate can match the nitrogen cutting, which is economical. An efficient cutting method. However, the disadvantages on the cut surface are also obvious. First of all, the air-cut section will produce a bottom burr, and the laser processed product must also undergo secondary processing such as deburring, which is not conducive to the entire product production cycle. Secondly, the air-cut section is easy to blacken, which affects the quality of the product. Therefore, laser processing does not require the advantages of subsequent processing, so many companies are reluctant to choose the air cutting method in the processing of galvanized steel sheets.


              Oxygen cutting:

              This is the most traditional and standard cutting method. The advantage is that the gas cost is low, and in the processing of sheet metal mainly carbon steel, it is not necessary to frequently switch the auxiliary gas, which is convenient for factory management. However, the disadvantage is that after the oxygen is cut, a layer of scale is left on the surface of the cut surface. If the product with scale is directly welded, the scale will naturally peel off after a long time. This is one of the reasons why galvanized sheet welding is easy to solder.
