Embodiment Construction

[0012] 1. Place and fix the tube body on the rotating bracket;

[0013] 2. Align and fix the middle flange with the pipe body or pipe and pipe; assemble the round pipe and flange together according to the drawings, and divide the flange into 8 equal parts on average;

[0014] 3. Heating the intermediate flange and the connection position with the pipe body can prevent the oversized components from being welded through and generating stress; it can prevent cracks and reduce the hardening degree of the heat-affected zone.

[0015] 4. The middle flange is welded to the pipe body by full penetration;

[0016] 5. Align and fix the flanges at both ends with the two ends of the pipe body;

[0017] 6. The flanges at both ends are welded to both ends of the pipe body by full penetration; while welding, the bracket is rotated synchronously to ensure consistent weld seam and penetration; segmental symmetry and multi-layer are used for welding. welding.

Abstract

A flange welding method for the column top connection member of a roller coaster: place and fix the pipe body on the rotating bracket; align and fix the intermediate flange with the pipe body or pipe and pipe; connect the round pipe and the flange Assemble together according to the requirements of the drawings, and divide the flange into 8 equal parts on average; heat the middle flange and the connection position with the pipe body to prevent the oversized components from being welded through and generating stress; to prevent cracks and Reduce the degree of hardening of the heat-affected zone. The middle flange is welded to the pipe body by full penetration; the flanges at both ends are aligned with the two ends of the pipe body and fixed; the flanges at both ends are welded to the pipe body by full penetration At the same time as welding, the support is rotated synchronously to ensure consistent weld seam and penetration; when welding, segmental symmetry and multi-layer welding are adopted; the rotating support is used to weld the flange, which has good rotation stability and convenient operation. The welding seam is uniform, so as to obtain the welding method of the flange with high welding precision and good quality.

Description

technical field [0001] The invention relates to a welding processing method, a flange plate welding method of a column top connecting member of a roller coaster, and a round pipe butt welding method. Background technique [0002] In the prior art, the connecting member used for the column top of the roller coaster is composed of a pipe body and flanges welded in the middle and both ends of the pipe body. Since the pipe body and the flange are large in volume, if the welding quality does not meet the requirements , the use of roller coasters will bring adverse consequences. Contents of the invention [0003] The purpose of the present invention is to provide a flange welding method for the column top connecting member of a roller coaster and a round pipe butt welding method in view of the above-mentioned problems in the prior art. The welding quality can be guaranteed by using this method. [0004] Provide a roller coaster column top connecting member flange welding method...
