Abstract

The invention discloses a nondestructive testing apparatus for welded pipe joints. The nondestructive testing apparatus is characterized by comprising: a material storage unit having a material outlet, a material discharging unit and a transporting unit. In the direction of transporting the pipe joints, a nondestructive testing work station, a retest work station and a sorting and material-discharging work station are successively disposed. An in-place detection unit is arranged on each of the nondestructive testing work station and the sorting and material-discharging work station. A nondestructive testing unit is disposed on the nondestructive testing work station. A retest transporting unit is arranged on the retest work station. A sorting unit and a classifying and material-storing unit are arranged on the material-discharging work station. The apparatus is simple in structure design, is low in production cost, is convenient to use, allows nondestructive testing and automatic sorting operations to pipe joints in different diameters, has high practicability and universality and is convenient to use in production workshops at large scale.

Description

technical field [0001] The invention relates to a device for non-destructive flaw detection of short pipe joints after splicing and welding the circular seams. Background technique [0002] At present, some short pipe joints in the boiler header are designed as dissimilar steel butt joint structures. This type of short pipe joints needs to be tested by non-destructive testing after circumferential seam splicing welding. At present, manual detection is used for non-destructive testing, which requires manual placement of a large number of short pipe joints in order. Non-destructive testing also requires manual marking of short pipe joints, and manual inspection of qualified products / Unqualified pipe joints are sorted. This kind of production method will consume a lot of manpower and material resources of the enterprise, which is not conducive to workshop production. Contents of the invention [0003] The object of the present invention is a device capable of automatic non...
