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.

Our consulting 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

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

Weld troubleshooting and subsequent redesign on a heater that had a limited structural life. The heater was constructed of .025 inch thick stainless steel. The configuration includes an edge weld joint type, where two .025 sheets are placed side-by-side and the top surfaces are welded. When this is connected to the header, a three point T weld joint configuration is created by the intersection of the radial and tangential faces of the header and tube sheet. Many fatigue cracks initiated in this area.

  • 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 on welded assemblies and weld repairs to minimize weld residual stress and mitigate various damage mechanisms. Engineering support is required to minimize potential 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).
