Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding auxiliary devices, in particular to a lifting module transversely movable device. Background Art
[0002] With the continuous development of my country's economy and the acceleration of industrialization, the demand for resources such as oil and natural gas is growing. In order to meet this huge demand, my country has actively taken measures, one of which is to establish important natural gas pipeline projects such as the West-East Gas Transmission Project. These projects not only strengthen the allocation capacity of domestic resources, but also ensure the stable supply of energy. As high-strength pipeline steels, X70 and X80 are widely used in these oil and gas pipelines due to their excellent performance. They have the characteristics of high strength, good corrosion resistance, weldability and processing performance, which can ensure the safe and stable operation of pipelines under harsh environments such as high pressure and high corrosion. However, in the welding of straight seam welded pipes, weak areas will appear in the weld, such as low-carbon martensite in the heat-affected zone of the weld, which will deteriorate the toughness of the weld, thereby affecting the quality of the welded pipe and reducing the service life of the welded pipe. Diffusible hydrogen will also appear in the weld, which will cause cracks inside the weld, thereby reducing the strength and toughness of the weld. Excessive diffusible hydrogen content will cause hydrogen embrittlement in the weld and cause corrosion. In response to these problems, it is necessary to take preheating measures before welding. Preheating before welding can significantly slow down the cooling rate after welding, which helps the escape of diffused hydrogen in the weld metal, thereby avoiding hydrogen-induced cracks. At the same time, it also helps to reduce the hardening degree of the weld and the heat-affected zone, and improve the crack resistance of the welded joint. By uniformly preheating the weld locally or overall, preheating before welding can reduce the temperature difference between the welded workpieces in the welding area, thereby significantly reducing welding stress. This reduction in stress helps prevent deformation during welding, makes the weld stronger, and improves welding quality. The lifting module of the existing preheating device before welding can only move vertically up and down, and can only preheat the welded pipe that is equal to or less than the length of the heating blanket. The welded pipe that exceeds the length of the heating blanket cannot be preheated at one time, and two or more parts cannot be preheated at the same time. Utility Model Content
