When we use an object, we will learn about the basic information of the object to see which is useful or helpful to us. The steel structure is the same, so will the interface of steel structure processing rust?Let’s make up a small series of HJSD steel structure engineering to talk about it for us.

    Cutting methods include: gas cutting, mechanical cutting and plasma cutting.

   (1) Gas cutting method: the preheating flame produced by mixing oxygen and combustible gas is used to heat the metal surface to the combustion temperature, so that the metal is violently oxidized.A large amount of heat is released to promote the lower layer metal to burn by itself, and the oxide is blown away by high-pressure oxygen jet, forming a narrow and regular gap.With the movement of cutting joint, the required shape of steel structure construction drawing is cut out.Before gas cutting, rust, dirt, etc.The area on the steel cutting surface shall be removed.After gas cutting, slag and spatter shall be removed.

   (2) Mechanical cutting method: the relative movement of the upper and lower scissors can be used to cut off the steel, or the cutting movement of the saw blade can be used to separate the steel, or the friction heat between the saw blade and the steel structure can be used to melt the metal and cut off.The commonly used cutting machines are shears, punching shears, hacksaw machines, grinding wheel cutting machines, etc

   (3) Plasma cutting method: through high-temperature and high-speed plasma flame flow, the metal and its oxide at the incision will be melted and blown off to complete the cutting, so that any metal can be cut, especially stainless steel, aluminum, copper and other high melting point non-ferrous metals.

     The above is a small editor to introduce the relevant content about whether the interface of steel structure processing will rust, hoping to bring help to you. If you want to know more, please continue to pay attention to us, please consult HJSD steel structure engineering for details.
