When inspecting a weld, there are many different assessments to make for it to pass the quality and safety standards relevant to that construction. Two of these are the weld size and weld discontinuities.

Weld Size

The size of a weld is important to assess as this often relates directly to the weld’s strength and associated performance. Undersized welds are structurally unsuitable for the stresses of a completed construction. As such the weld size must be of adequate length and width in relation the final use of the construction.

Weld Discontinuities

Weld discontinuities are imperfections that can either be directly on the weld itself, or anywhere in close proximity. Like an inadequate weld size, these can also affect the intended performance of the construction.

When of unacceptable size or location, discontinuities are referred to as welding defects. Assessing and spotting any instances of this is critical during a welding inspection as it can cause direct premature weld failure.
