Problems solved by technology

[0003] When the existing spot welding technology welds steel plates or aluminum alloys, the semi-finished products after welding are often inspected by means of ultrasonic, chisel inspection or visual inspection, which cannot realize real-time welding quality monitoring and process control, resulting in low detection efficiency. And problems such as welding quality is difficult to control

Abstract

The invention discloses an on-line detecting system and method for spot welding. The system comprises a welding machine, area array probes, a supersonic module, a main engine and a server. The welding machine is provided with welding heads, and the area array probes are arranged in the welding machine in an integrated mode. The supersonic module is connected with the area array probes, the main engine is connected with the supersonic module, and the server is connected with the main engine; the welding heads output a voltage or an electric current to a work piece for spot welding and welding spots are formed, the area array probes are excited by the supersonic module to output detection ultrasonic waves to a spot welding position on the work piece, and the supersonic module further receives rebound ultrasonic waves rebounded from the spot welding position. The on-line detecting system and method for spot welding have the advantages that real-time monitoring to a spot welding process of a welding position is achieved, and the accuracy of detecting the spot welding process of the welding position is improved, so that the real-time monitoring and process management on a welding work of the welding machine are achieved, the ability of quality control over the spot welding process is improved and the detection efficiency and the welding quality of the welding spots are improved.

Description

technical field [0001] The invention relates to the detection field, in particular to an on-line spot welding detection system and detection method. Background technique [0002] Spot welding is a high-speed and economical connection method that welds individual points on the contact surface of the weldment at the joint; it is suitable for the manufacture of stamping and rolling that can use lap joints, the joints do not require airtightness, and the thickness is less than 3mm. made of thin plate members; [0003] When the existing spot welding technology welds steel plates or aluminum alloys, the semi-finished products after welding are often inspected by means of ultrasonic, chisel inspection or visual inspection, which cannot realize real-time welding quality monitoring and process control, resulting in low detection efficiency. And welding quality is difficult to control and other issues. Contents of the invention [0004] In order to solve the above problems, the pr...
