Abstract

The invention is concerned with the auxiliary welding equipment and the welding method for connecting flange, the equipment includes the main body that is a strip square bar with inverse T-shape slot and several chucks fixing on the main body, the top of the chuck is plate-shape body, the middle of the chuck is shore, the bottom of the chuck is squareness base, sets the location hole crossing the upper surface and bottom of the plate-shape body on the plate-shape body, the upper surface edge of the plate-shape body is the ring protruding table with several gaps, the chuck fixes on the main body by embed the squareness base in the inverse T-shape slot, sets the strainer resisting the squareness base on the chuck fixing position of the main body. The invention can ensure the welding quality, improve the work efficiency, short the manufacturing cycle, reduce the manufacturing cost.

Description

technical field [0001] The invention relates to flanges, in particular to a welding auxiliary device and a welding method for connecting flanges. Background technique [0002] The structure of most header pipes on marine low-speed diesel engines is related to the number of cylinders in the cylinder block, that is, most of the header pipes have multiple branch pipes. There is a flange on the end of the branch pipe on the same main pipe, and the flange must strictly correspond to the corresponding welding flange on the diesel engine, so that no mistakes will occur when the pipe fittings are installed on the diesel engine. The location distribution has higher requirements. [0003] Taking the welding flange of the lubricating oil inlet pipe of the main bearing on the marine diesel engine frame as an example to illustrate the problems caused by the current technology. [0004] In the prior art, the welding flanges are first welded to the side panels of the frame one by one by ...
