Description

technical field [0001] The invention relates to electrofusion welding of polyethylene pipes, in particular to an electrofusion welding machine for realizing welding quality monitoring through a wireless network and a method for realizing electrofusion welding quality monitoring through a wireless network. Background technique [0002] Electrofusion welding is one of the main connection methods of polyethylene pipes. It has been widely used in the field of polyethylene gas pipelines due to its high safety and low accident rate. However, at present, there is no set of standards for the detection and safety assessment of polyethylene pipe electrofusion joints at home and abroad. The detection and safety evaluation methods of traditional steel pipes are not suitable for polyethylene pipes, so it is impossible to detect and evaluate the electrofusion joints of polyethylene pipes in service. Thus, a vacuum of safety supervision is formed on the polyethylene pipe, and safety is di...

However, these welding machines cannot avoid the occurrence of welding defect factors that are most likely to cause welding defects in the above four projects

Although these types of welding machines are all traceable, they have obvious shortcomings such as easy loss, difficulty in finding, and small amount of recorded data because they use methods such as stand-alone storage and printing.

[0005] Utility model patent CN200720093689.2 proposes a new type of intelligent high-frequency electric fusion welding machine, which has the advantages of preventing voltage fluctuations during welding, high voltage output accuracy, light weight, and energy saving. changes, and cannot realize the functions of positioning the welding joint or storing and managing the welding process data.
