Problems solved by technology

[0003] 1. In the process of aligning the U-shaped pipe and the steel pipe, the steel pipe and the U-shaped pipe are likely to shift or slide relative to each other due to excessive impact force, resulting in poor welding effect or even failure;
[0004] 2. During the welding process, the existing equipment cannot adjust the angle of the welding head, and cannot perform batch welding, resulting in low welding efficiency

Abstract

The invention provides a welding process for manufacturing a boiler economizer. The welding process for manufacturing the boiler economizer adopts the following equipment for welding, the equipment comprises a base, a fixing device and a welding device, the lower end of the base is connected with the existing ground, the fixing device is installed at the upper end of the base, and the welding device is arranged above the fixing device. Through cooperation of a supporting plate and a fixing plate, a combined body of a steel pipe and a rib plate in the boiler economizer can be supported, through cooperation of a fixing rod and an arc-shaped block, the steel pipe can be limited and fixed, through an arc-shaped groove, the attaching degree between a supporting table and the steel pipe can be higher, meanwhile, by arranging a first sponge, the friction force between the steel pipe and the arc-shaped groove can be increased, so that the situation that the welding effect is affected due to the fact that the steel pipe slides or shakes relative to the arc-shaped groove in the alignment and welding process is avoided.

Description

technical field [0001] The invention relates to the field of boiler economizers, in particular to a manufacturing and welding process for boiler economizers. Background technique [0002] The economizer is a device installed in the lower part of the flue at the tail of the boiler to recover the waste heat of the exhausted smoke. It heats the boiler feed water into the heating surface of saturated water under the pressure of the steam drum. It reduces the exhaust temperature of flue gas, saves energy and improves efficiency, so it is called an economizer, and the steel tube economizer is a common type of boiler economizer. The steel tube economizer is not limited by pressure. , can be used as a boiling type, generally made of carbon steel pipe with an outer diameter of 32 to 51 mm, and sometimes fins and ribs are added to the pipe to improve the heat transfer effect. The head tube (commonly known as the serpentine tube) is composed of the steel tube economizer. In the manufa...
