Apparatus and method for optically surveying and/or examining a welding componentry

Apparatus for optically surveying and/or examining a welding componentry, comprising:

• a measuring space;
• a plurality of cameras disposed in the measuring space for taking images of the welding componentry;
• an evaluation unit for evaluating the images;
• a support unit disposed in the measuring space for support of the welding componentry, said support unit including a base plate and at least two support columns on the base plate;
• and
• a plurality of clamping units, each of the clamping units being provided on a free end of a corresponding one of the support columns and movable in a vertical direction relative to the base plate, whereby the clamping units and the support columns are placed into one-to-one correspondence, each clamping unit including two clamping elements constructed for movement relative to one another for clamping the welding componentry, wherein at least one of the support columns has a pin with a support surface for the welding componentry and movable in relation to the clamping unit in the vertical direction and in a sideways direction that is different from the vertical direction.
