Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is a high-tech enterprise specialized in the design, development and manufacture of welded pipe equipment, spiral welded pipe equipment, cold-formed steel equipment, sheet and pipe finishing equipment and high-precision slitting line equipment. Taiyuan Huaxin Cheng electromechanical equipment for you to resolve welded pipe mill in the production of oil casing pipe unit should pay attention to what the oil in the production casing first thing to note is that the strength and toughness in the production process through hot stretch reducing controlled cooling This sub-problems can largely improve weld pipe welding unit left on the oil casing, while enhancing the strength and toughness. The main factor in the formation of gray leaf spot weld tubing and casing include the chemical composition of the base metal welding temperature, welding speed welding. Want to avoid the cross-cut gray leaf spot welding equipment in the production, we should pay attention to the strict control of the process equipment offer a cross-cutting and welding strip edge quality, the use of pre-weld heat treatment and thermal tension reducing whole tube heating method to avoid oil casing gray spots appear on the weld. Pipe welding unit wants to avoid the production of oil casing shaped groove weld corrosion can occur by thermal tension reducing methods to avoid. Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is a high-tech enterprise specialized in the design, development and manufacture of welded pipe equipment, spiral welded pipe equipment, cold-formed steel equipment, sheet and pipe finishing equipment and high-precision slitting line equipment. Taiyuan Huaxin Cheng electromechanical equipment for the reasons you resolve slotted pipe equipment which occurs when welding? There may be a physical reason for Buying transverse shear device that caused slotted magnet. Magnet magnetic field generated in the tube welding process, will result in a high-frequency current is concentrated in the weld was "V" shaped area of ??the cross-cutting equipment, making the weld in a very short period of time to reach the hot spots. By the magnet causes slits is able to identify them more obvious, the slotted weld in this case is usually black and red, no splashing spark, weld shape for the whole cardigan, sometimes even welding lived, Welding is also false. How much cross-cutting device transverse shear _ _ Huaxin Cheng electromechanical equipment provided by the Electrical and Mechanical Equipment Co., Ltd., Taiyuan Huaxin Cheng.
