Embodiment

[0032] Please combine Figure 1-2 It should be understood that a method for detecting the welding quality of pipe fittings includes the following steps:

[0033] S0: cleaning the impurities on the two side walls 21 and 22 of the weld 1;

[0034] S1: fixing a copper wire 3 with a diameter of less than 1mm on the bottom of the weld 1 along the path extending horizontally of the weld 1;

[0035] S1.1: heating the two side walls 21, 22 of the weld 1, so that the surfaces of the two side walls 21, 22 of the weld 1 are in a molten state;

[0036] S1.2: Heating the welding material so that the welding material is in a molten state;

[0037] S2: Fill the weld 1 with welding material until the welding material in the weld 1 is flush with the outer wall of the pipe fitting;

[0038] S2.1: Squeeze the welding material in the welding seam 1 with a pressing block, so that the welding material can fill the welding seam 1;

[0039] S2.2: cooling the welding material in the weld 1;

[00...

Abstract

The invention discloses a detecting method for pipe welding quality. The detecting method includes the following steps that firstly, a metal wire is fixed to the bottom of a weld joint along a route formed by the weld joint extending in the horizontal direction; secondly, the weld joint is filled with a welding material; thirdly, a spark induction testing head of an electrostatic spark sensitivity testing instrument is used for conducting scanning on one side of a welding opening of the weld joint; and fourthly, the position where the discharge phenomenon happens is recorded in the scanning process of the spark induction testing head. The detecting method has the beneficial effects of being simple and convenient to implement, easy to operate and low in cost.

Description

technical field [0001] The invention relates to a method for detecting the welding quality of pipe fittings. Background technique [0002] The welding between pipe fittings is usually done by filling welding materials to realize the combination between pipe fittings. However, due to various reasons, air bubbles will be generated inside the welding material during the filling process, and the existence of air bubbles will have an adverse effect on the quality of pipe fitting welding. [0003] Since air bubbles are generated in the welding material of the weld seam and cannot be observed by naked eyes, how to provide a convenient and low-cost inspection method for the welding quality of pipe fittings has become a major problem in the inspection of pipe fitting welding quality. Contents of the invention [0004] The technical problem to be solved by the present invention is: the welding quality of the pipe fittings cannot be detected after the pipe fittings are welded, and a...
