Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of welding auxiliary equipment, and particularly relates to a thin-walled part welding anti-deformation adjustable supporting structure. BACKGROUND

[0002] Small-diameter pressure vessels often appear in the field of pressure vessels or chemical industry. The characteristic of such vessels is that the cylinder diameter is very small, the human body is difficult to enter, the cylinder wall is very thin, and the cylinder length is relatively long, and the length L can reach 1-2 meters. At this time, when a small connector is welded on the cylinder, according to the welding deformation law, the cylinder will locally shrink and sink (the welding deformation of stainless steel material is more serious), and the connector axis will also deviate from the theoretical position. In order to ensure the perpendicularity of the connector and the roundness of the cylinder, anti-deformation measures need to be taken. However, due to the fact that the position of the connector is too far from the end face of the cylinder, the hand cannot operate, and the traditional anti-deformation method cannot be implemented.
