Weld Testing and Troubleshooting

We perform weld troubleshooting services, including inspection/ analysis, providing repair solutions to manufacturing and field welding issues – keeping you compliant to AWS and other relevant Codes.

These services include weld testing & analysis, joint analysis, weld procedure specification & qualification, as well as (weld distortion/ cracking /corrosion/ fatigue) troubleshooting, weld failure analysis, and repair of noncompliant issues.

See Portfolio to read about more projects.

Our services also include Certified Weld Inspection Services (CWI). From the inspection results, we provide engineering analysis and effective weld repair solutions, often through the use of three-dimensional finite element analysis (FEA) to quantify residual welding stresses, fatigue strength reduction due to lack of fusion, underpenetration, inclusions and other imperfections.

Using various AWS codes including AWS D1.1, AWS D1.5 as well as API and ASME codes – we resolve issues including:

  • Weld Distortion/ Cracking
  • Weld Failures
  • Weld Defects/ Porosity
  • Fatigue of Welded Joints
  • PWHT/ Heat Treatment Issues
  • Weld Corrosion/ SCC Issues
  • Welding Metallurgy
  • Weld Non-conformance

We investigated the cause of a fractured axle bracket. Shown here is a high magnification where a small portion of the weld metal adhered to the bracket. Slag is observed under the initial weld pass and the frame surface, indicating that the weld failed due to lack of fusion.

  • Durable welding is what holds every plant together. Often, equipment design life is often compromised through inadequate manufacturing processes such as welding, thermal/ transient conditions, and high temperature conditions. At elevated temperatures, creep, and component strains occur, especially in welded connections.

    Defects often occur in welded, cast and forged parts. Parts with complex geometries often include crack starters such as metallurgical notch effects. We provide Certified Weld Inspections (CWI) and Nondestructive Testing (NDT) including radiographic (RT) and ultrasonic (UT) to determine quality and serviceability. Read about the various types of NDT.

    Often, local post-weld heat treatment (PWHT) operations are performed in weld and weld repairs to minimize weld residual stress and mitigate various damage mechanisms. Engineering support is required to minimize potential weld non-compliances. We provide such support (including FEA) to optimize PWHT arrangements and thermal gradients to prevent detrimental distortion, cracking, or excessive residual stress.

    Examples Include:

    • Manufacturing
    • Petrochemical
    • Mining
    • Oil/ Gas
    • Power Generation
    • Assemblies
    • Machinery
    • Presses
    • Supports
    • Cranes
    • Pressure Vessels
    • Heat Exchangers
    • Ductwork
    • Condensors
    • Reactors

    We are experienced, multi-disciplined engineers providing clients with support across the spectrum of welding and joining challenges – including troubleshooting, code compliance, weld and joint inspection, mechanical testing, and evaluation of welding procedure specifications (WPS), procedure qualification records (PQR), and welder performance qualifications (WPQ).

    Several of our senior engineers have developed patents, published technical reports, and have been active in Codes and Standards Committees including the American Society of Mechanical Engineers (ASME), the National Association for Corrosion Engineers (NACE), the American Nuclear Society (ANS) and the American Welding Society (AWS).
