Embodiment 1

[0033] Such as figure 1 As shown, the embodiment of the present invention relates to an intelligent welding method for electrofusion pipe fittings based on position detection, and the intelligent welding method includes:

[0034] Parameter setting steps: set one end of the electrofusion pipe to be equipped with N coils of resistance wire and the layout width is L, and then calculate the cladding width of each coil of resistance wire as L / N;

[0035] Specifically, assuming that one end of the electrofusion pipe fitting is provided with 50 turns of resistance wires of the same direct size, and the laying width is 20 cm, it can be calculated that the cladding width of each turn of resistance wire is 4 mm.

[0036] When the relationship between the actual current and the maximum output power is measured, the total resistance of the resistance wire is R when the requirements are met, and the average resistance value of each turn of the resistance wire is calculated as R / N at this t...

Embodiment 2

[0060] Another embodiment of the present invention includes a storage medium on which a computer control program is stored, and when the computer control program is executed by a processor, the intelligent welding of electric fusion welding pipes based on position detection in Embodiment 1 of the present invention is realized method steps.

Embodiment 3

[0062] Another embodiment of the present invention includes a terminal, including a processor and a memory; the memory is used to store a computer control program; the processor is used to execute the computer control program stored in the memory, so that the The terminal executes the steps of an intelligent welding method for electric fusion welding pipes based on position detection in Embodiment 1 of the present invention.

[0063] The invention realizes the measurement of the resistance of the gap width and insertion depth through the change of the current calculated by the temperature and resistance changes in the resistance wire welding process, and then calculates the specific values ​​of the gap width and insertion depth, and determines the insertion of the pipe fitting Whether it is inserted in place, it can also be accurately calculated how many turns of the resistance wire the heat from cannot be transmitted because it is not in contact with the inserted pipe fitting,...

Abstract

The invention relates to an intelligent welding method for an electric melting pipe fitting based on position detection, a storage medium and a terminal. The method comprises the steps that current monitoring is carried out, specifically, an actual relation curve between welding time and welding current in the welding process is monitored in real time, and the actual relation curve and a standard relation curve are compared and analyzed; insertion position judgement is carried out, specifically, if the actual welding current is smaller than the standard current or is not within the error range of the standard current, it is indicated that the inserted pipe fitting is not inserted in place at the moment; and clearance position detection is carried out, specifically, the total actual resistance value R<actual> of a resistance wire at the moment is calculated, and the clearance width of the inserted pipe fitting is calculated by combining R/N and R<m>/N. According to the intelligent welding method, the storage medium and the terminal, the change of the current is calculated through the change of the temperature and the resistance in the resistance wire welding process, the measurement of the resistance of the clearance width and the insertion depth is realized, the specific values of the clearance width and the insertion depth are calculated, whether the inserted pipe fitting is inserted in place is judged, and therefore the welding quality of the pipe fitting is greatly improved, and the service life of the pipe fitting is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of electric fusion pipe fitting welding, in particular to an intelligent welding method for electric fusion pipe fittings based on position detection, a storage medium and a terminal. Background technique [0002] When polyethylene pipes are connected by electrofusion welding, the quality of pipe joints is easily affected by environmental factors and human operation factors; in the welding process, two general pipe fittings are generally inserted into both sides of the electrofusion pipe fittings, and then passed The resistance wires on both sides of the electric fusion pipe are heated and clad to the electric fusion pipe, so as to achieve the purpose of welding with two general pipes. However, the electric fusion pipe fittings are only provided with resistance wires within a certain distance on both sides. Generally, the depth of the insertion pipe fittings into the electric fusion pipe fittings is equal to...
