Since during the production and use of elbow pipes, defects such as pores, slag inclusions, and cracks may occur in the welds, and these defects may affect the integrity and safety of the pipeline. X-ray detection is a non-destructive detection method that can clearly show the defects inside the weld to ensure that the welding quality meets the standard requirements and guarantee the normal operation of the pipeline system and the safety of personnel.

[0003] Due to the irregular shape of the elbow pipe, for the detection of elbow pipe welds, it is all carried out by staff holding the X-ray device for circumferential detection. However, if the staff holds it, it is easy to make mistakes, and at the same time, it is also easy to shake, resulting in the situation of undetected detection. If the machine-fixed detection method is used, due to the different uses of many elbow pipes, their shapes are different. When the conventional equipment is fixed, the clamping method needs to be adjusted according to the shape of the elbow pipe, and this step takes a lot of time, which is time-consuming and laborious.
