304 seamless stainless steel tubes need to be cut during use because they have to adapt to various working places and methods. There are only a few common cutting methods, such as oxygen gas flame gas cutting, water jet melting electrode arc cutting method, laser Cutting method, etc. These cutting methods are also very common. Let's talk about the common cutting methods of 304 stainless steel seamless pipes.
Water-jet melting electrode arc cutting method: Water-jet melting electrode arc cutting method relies on the contact between the cutting wire and the workpiece to ignite the arc to melt the metal, and then it is impacted and granulated by high-pressure and high-speed jet water, and is quickly discharged. The movement forms the incision. Due to the action of high-pressure jet water, the heat-affected zone of the incision is eliminated, which is extremely beneficial to cutting 18-8 stainless steel, which can reduce or avoid the occurrence of intergranular corrosion.
Laser cutting method: Laser cutting is a new type of thermal cutting method. A rising star for thermal cutting stainless steel. It is a method of thermally cutting stainless steel using the high energy of laser technology. It can be used to cut metal and non-metal, and some people call the laser "cutting tool".
Oxygen gas flame gas cutting: Gas cutting is a method of using the thermal energy of the gas flame to preheat the cutting part of the workpiece to a certain temperature, and then spray a high-speed cutting oxygen flow to burn the metal and release heat to achieve thermal cutting. When cutting stainless steel with an oxygen gas flame, the main difficulty is the formation of high-melting chromium oxide on the surface of the cut, which prevents the metal from burning, resulting in the difficulty of continuous cutting. In order to cut stainless steel smoothly, in addition to having sufficiently pure oxygen with a certain pressure and a good cutting wind line, oxygen flux gas cutting and vibration gas cutting can be used.
