  • The cutting fluid produces bubbles, how can we solve it?

    In the metal cutting and grinding process, cutting fluid is an industrial liquid used to cool and lubricate tools and processed parts. The reasonable use of cutting fluid in cutting can not only reduce the friction between the tool and the chip, the tool and the processing surface, but also It can reduce the cutting force and cutting temperature, reduce tool wear, and improve the quality of the machined surface. But what do you know about the classification of cutting fluid? What is the choice of cutting fluid?

  • Get to know the four metal 3D printing technologies

    Metal 3D printing is considered the culmination of all 3D printing. When it comes to strength and durability, nothing can compare to metal. The earliest metal 3D printing patent was DMLS (Direct Metal Laser Sintering), which was obtained by the German EOS in the 1990s.

  • This article takes you to learn more about the process method of aluminum alloy welding

    Aluminum alloy welding is very different from the welding of ordinary carbon steel, stainless steel and other materials. It is easy to produce many defects that other materials do not have, and it is necessary to adopt targeted measures to avoid it. Let's take a look at the problems that are prone to aluminum alloy welding and the requirements for welding technology.

  • What are the welding methods?

    Welding is "the process of joining metals or non-metals locally by heating the material to the welding temperature, applying pressure or not, or only by applying pressure, with or without the use of filler materials," and joining means "connecting together" , So welding refers to the operation activity of realizing connection.

  • How to cleverly solve the problem of oxidation on the back side of stainless steel pipe welding?

    When welding stainless steel pipes in petrochemical construction, the surface of the weld bead and the heat-affected zone are prone to oxidation and discoloration. In order to ensure the corrosion resistance of stainless steel, the weld is pickled and passivated after welding to form a dense layer on the surface.
