Application overview

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.

  • 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.

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.

Why choose laser equipment to process galvanized sheet？

 

In the process of processing galvanized sheet, it is necessary to increase auxiliary gas, auxiliary gas purity and pressure linear impact cutting plate section quality. Oxygen purity for cutting should be above 99.6%.The higher the purity of oxygen, the higher the roughness and quality of the section. Nitrogen purity should be more than 99.5% when cutting, the progress of nitrogen purity can ensure that in the process of cutting galvanized plate slit does not change color.
