DEVICE TO ASSESS QUALITY OF WELDED JOINT Russian patent published in 2015 - IPC B23K37/00 G01B15/08 B23K9/10 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the field of welding, in particular, to a device for assessment of joint surface quality, and may be used in metering control of quality of welded joints produced by soldering or any available welding method, in process of formation of which there is a liquid phase of joint material crystallised in the field of gravity forces, assessment of quality of welding materials and welding equipment. The device additionally comprises a computing unit, where on the basis of values received from the reading device they detect borders of a welded joint in the direction transverse to the axis of the welded joint, detection of welded joint width, building of 2D image of the welded joint surface for each step of reading device movement, building 3D image of welded joint surface from the produced 2D images, detection of the shape of reference surface by normative values of height and width of the joint, comparison of produced 2D and 3D images of the welded joint surface with the shape of surface of the reference and detection of the value of welded joint surface shape deviation from the shape of the reference surface.

EFFECT: technical result consists in provision of qualitative assessment of welded joint surface, which results in increased accuracy of assessment.
