Efficiency optimization of welding process of used high frequency welded pipe production line（2）
The high-frequency welding process is the most widely used method for the production of welded pipes by used high frequency welded pipe production line. It heats the metal by applying or inducing an electric current across the edge of the strip before the closing point of the open pipe, and presses the tube blank through squeeze rollers, The molten metal and inclusions are squeezed out of the weld pool to form a forged weld. But there is still a lot of room for improvement in this area. By designing and transforming the high-frequency welding process of the tube on the original basic configuration and operating it effectively, the welding process can be optimized, the welding efficiency can be improved, and the cost can be greatly reduced. -

142023-03Defects caused by improper removal of internal burrs on used welded pipe machine
Whether the burr removal process of the used welded pipe machine is appropriate directly affects the quality of the welded pipe. Sometimes grooves are left due to the scraping of the scraper, which is rejected by the user as a welding defect, which brings serious economic losses to the steel pipe manufacturer.

192023-03Analysis of quality defects in welding section of used pipe welded machine
The weld seam is the most important sign of the quality of the welded pipe and the life of the welded pipe. Therefore, the analysis and treatment of quality defects in the welding section of the used pipe welded machine should be carried out around the weld. The main defects of the weld include cracks, cracks, incomplete penetration, over-burning and perforation, and dislocation of the weld. -
162023-03Discussion on the service life of welded pipe rolls of metal roll forming machine
In the production of metal roll forming machine, rolls are important key tools. Roll consumption is also an important economic indicator for controlling production costs. In addition, whether the roll can work normally will directly affect the output and quality of welded pipe production, so welded pipe manufacturers attach great importance to and strive to improve the life of the roll. -
132023-03Influence of different wall thicknesses made by steel roll forming machine on the properties of the heat-affected zone of the weld and its countermeasures
The properties of the heat-affected zone of the weld seam of the steel roll forming machine are closely related to the quality of the welded pipe. The width, metal streamline angle and metallographic structure of the weld heat-affected zone under different process parameters are studied by examples, and the microscopic approach that is conducive to stability and improving the welding quality of the welded pipe is explored. -

182023-03Influence of welding process on welding quality of cold roll forming machine
Whether the welding quality of the cold roll forming machine meets the standard depends on the welding process. The welding process generally affects the quality of the welded pipe. The following describes the influence of the welding process on the welding quality of the cold bending forming machine. -
152023-03High frequency welding of steel roll forming machine
The welding of stainless steel pipe made by steel roll forming machine is very different from that of carbon steel pipe in terms of process. The most notable is the oxides produced by the molten stainless steel during welding. The oxide melting point of carbon steel is lower than that of the base metal, and it melts before the base metal and is more easily extruded by the extrusion roller to form burrs. The metal composition of the solution pool is very clean, and the base metal is very bonded during the forging and welding process. close. The control of stainless steel oxides is extremely difficult, which easily leads to welding defects. -
122023-03Adjustment of Welding Squeeze Roller for used high frequency welded pipe machine (2)
In the production of used high frequency welded pipe machine, the forming joint state of the tube blank directly affects the quality of the weld, and the parallelism of the butt surface of the welded joint is particularly important. In the process of seam welding of steel pipes, the parallelism of the seam is mainly ensured by adjusting the reduction amount of the upper roller of the squeeze roller and the gap between the two upper rollers. -
