Under the contract, which is scheduled from 1 June to 1 August 2013, five SGS certified welding inspectors, will be performing on-site inspections in Wisconsin.

SGS experts will perform inspections to identify, analyze, repair or replace failed welds and ensure safe functioning of the pipeline and prevent oil spills.

The team will identify welding discrepancies and offer solutions to repair them by using non-destructive testing methods.

Oil and gas companies have to accurately size and monitor pre-existing or growing weld discrepancies, such as cracking, porosity, incomplete penetration, inclusions and lack of sidewall fusion.

Regular monitoring and inspection programs help companies locate damages and discrepancies on pipelines and take timely action to prevent accidents.

In some cases, old sections of pipe are cut out and replaced with new pipe welded into place to ensure safe and reliable operations.
