Visual inspection at an early stage of production can also prevent under-welding and over-welding. Welds that are smaller than called for in the specifications cannot be tolerated. Beads that are too large increase costs unnecessarily and can cause distortion through added shrinkage stress.
After welding, visual inspection can detect a variety of surface flaws, including cracks, porosity and unfilled craters, regardless of subsequent inspection procedures. Dimensional variances, appearance flaws, as well as weld size characteristics, can be evaluated.
Results can be enhanced by using magnifiers and/or boroscopes.
Visual examination can be carried out in-house or on-site to meet your requirements.
