Weld testing is carried out to check the integrity of the weld (the join between two or more metals). This ensures adequate safety and soundness, and helps provide quality assurance. Carrying out checks on welded products means that poor welds and defects can be picked up before a failure occurs, therefore providing cost-effectiveness.

What can be Weld Tested?

Welding tests and inspection can be carried out on forgings, bars, plates, valves, seamless or welded tubular products, pressure vessels and pumps. It is performed on materials such as ferritic/austenitic stainless steels, austenitic stainless steels, nickel base alloys and carbon steel.

Typical reasons for failure of welds include cracking, insufficient penetration, incomplete fusion, porosity, poor penetration and undercutting.

These failures can be significant, as many are within buildings, pipelines etc. However, with welding checks and inspection, these failures can be minimised.

Should a failure occur during destructive weld testing, we have a team of qualified metallurgists on hand that can carry out a failure investigation to ascertain the cause of failure.

During a welding test, we carry out:

  • Tensile testing
  • Elongation
  • Impact
  • Macro and Micro examination (dependant on material)
  • Volume fraction
  • Hardness Surveys 
  • Corrosion – Pitting/Crevice resistance test or intergranular corrosion test (dependant on material)

Sectors requiring Welded checks:

  • Petroleum and natural gas industries
  • Aerospace
  • Automotive 
  • Infrastructure
  • Construction
