Description
Technical Field
[0001] The invention relates to the technical field of boiler processing, in particular to a welding tool for processing boiler steel structures. Background Art
[0002] A boiler is an energy conversion device that uses the heat energy released by fuel combustion or other forms of heat energy to heat the working medium (such as water, heat transfer oil, etc.) to certain parameters (such as temperature, pressure, etc.) to meet the demand for heat energy in industrial production or residents' lives.
[0003] The main components of a boiler include the boiler body and auxiliary equipment. The boiler body is mainly composed of two parts: the "pot" and the "furnace". The "pot" refers to the steam-water system, whose main task is to absorb heat and heat water into hot water or steam with a certain temperature and pressure; the "furnace" refers to the combustion system, whose main task is to make the fuel burn well in the furnace and release heat. Auxiliary equipment includes ventilation equipment, fuel supply and ash removal equipment, water supply equipment, water treatment equipment, detection instruments, automatic control, protection devices and auxiliary equipment, etc.
[0004] During the production and processing of existing boilers, steel materials are welded. When welding the inner tank of a small boiler, arc end faces need to be welded on both ends of the rolled steel structure. When welding, corresponding welding tools need to be used to position it. However, in actual use, existing welding tools often only have the function of positioning. During the welding process, the welding route is circular, so it is not adjustable. Workers need to change various postures for welding, which creates a high labor burden for the workers and affects the welding quality. Therefore, a new technical solution needs to be designed to solve this problem. Summary of the invention
