 The relationship between welding speed and weld quality should be understood dialectically and cannot be ignored. It is mainly reflected in the heating stage and the crystallization stage. 1. Heating stage Under the condition of high-frequency straight seam welded pipe (erw pipe), the edge of the tube blank is heated from room temperature to the welding temperature. During this process, the edge of the tube blank is completely exposed to the air without any protection, which must be violent with oxygen and nitrogen in the air. reaction, resulting in a significant increase in nitrogen and oxides in the weld. It is determined that the nitrogen content in the weld increases by 20-45 times, and the oxygen content increases by 7-35 times. At the same time, a large number of alloying elements such as manganese and carbon that are beneficial to the weld are burned and evaporated, resulting in a decrease in the mechanical properties of the weld. Therefore, in this sense, the slower the we...

 Seamless tube is a steel pipe that is perforated from a whole round steel and has no welds on the surface. According to the production method, seamless tubes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel tubes, extruded seamless steel tubes, and pipe jacking. Seamless steel pipes are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemical industries, boiler pipes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation. 1. The chemical composition of steel generally refers to the verified smelting composition obtained by sampling and analysis after smelting, and the verified composition that can be sampled for verification and analysis after processing. Verification ingredients should be within the allowable deviation range specified in the corresponding standard. 2. The size of the steel pipe mainly refers to the wall thickness and diameter, and t...
