In June 2012, 38 workers were exposed to tritium when a welding operation went wrong inside the protected environment of the reactor.

Eye protection used for welding operations is shaded to different degrees, depending on the specific operation.

Proper ventilation is essential to remove dangerous metallic fumes from welding operations.

Due in part to the growth of the oil industry, this symbol set was used during the 1990s in about 50% of the world's welding operations.

Alarms blared across the assembly line and the entire welding operation came to a grinding halt.

Situations in which welding operations are prohibited on equipment which contains:

Tetrachloroethylene should not be used near welding operations, flames, or hot surfaces.

The same crew then performed welding operations to equipment located above the control cables.

The perforations permitted the escape of flammable vapour, which was then ignited during the welding operations.

If new welding operations are started, then sparks can easily ignite the contents, with disastrous results for the welders.
