Description

TECHNICAL FIELD

[0001] The utility model relates to a welding seam molten depth detection technical field, specifically to a kind of welding seam sectioning post-molten depth detection level alignment positioning fixture. BACKGROUND

[0002] In the field of welding quality detection, the welding seam penetration is a key detection index. For some important welded structural members, the welding seam often needs to be sectioned for accurate measurement of the penetration. However, in the existing welding seam sectioning post-molten depth detection, positioning and alignment operations often have many problems. For example, the existing fixture structure is relatively complex, the operation process is cumbersome, and a lot of time and effort is required for sample alignment positioning. Moreover, it is difficult to ensure the horizontal state of the sample during the alignment process, which affects the detection accuracy. At the same time, the special shape and size of different welding seams also put higher requirements on the universality of the fixture. These problems result in low detection efficiency, insufficient result accuracy and reliability.
