Description

Technical Field

[0001] The present application relates to the technical field of weld detection, and in particular to a detection device for steel plate welds. Background Art

[0002] A weld is a seam formed by melting the joint between the electrode and the metal using the high temperature of the welding heat source. After the molten metal at the weld cools down, the two weldments are connected into a whole. According to the shape of the weld metal and the relative position between the weldments, welds can be divided into butt welds, fillet welds and electric riveting, among which butt welds are often used for splicing metal plates and steel sections. Due to the influence of various interference factors during the welding process, defects such as cracks, incomplete melting, incomplete penetration, depressions, slag inclusions and pores may occur at the welding site. These defects will lead to a smaller cross-sectional area of ​​the weld, low bearing capacity of the weldment, and stress concentration.

[0003] At present, the methods for non-destructive testing of weld defects mainly include visual testing, radiographic testing, penetration testing, etc. A Chinese patent with the announcement number CN217561408U discloses a weld defect detection system, including a mounting frame and a detection mechanism, the detection mechanism is connected to the mounting frame, a fixing mechanism is provided on the surface of the mounting frame, the fixing mechanism includes a fixing seat, a column and a clamping concave plate, the fixing seat is provided on the mounting frame, a plurality of columns are slidably provided on the fixing seat, a clamping concave plate is fixedly connected to one end of the column, and two clamping concave plates are slidably provided on the fixing seat.

[0004] With respect to the above-mentioned related technologies, the inventor believes that in the detection process of the above-mentioned weld defect detection system, the steel plate to be detected is installed between the two clamping concave plates on the fixing seat, and the steel plate weld is detected using a detection mechanism. However, the device can only detect the weld on one side of the steel plate. If the weld on the other side needs to be detected, the steel plate needs to be reinstalled and detected, which reduces the detection efficiency of the steel plate. Utility Model Content
