We provide design and inspection/ analysis of welded structures – as well as weld troubleshooting services, providing solutions to manufacturing and field welding issues.
These services include weld testing & analysis, weld overlay design and joint analysis, weld procedure specification and qualification, weld distortion/ cracking /corrosion/ fatigue troubleshooting, weld failure analysis, and weld repair of Code compliant issues.
- Weld Troubleshooting & Repair of a Heater with Limited Fatigue Life
- Weld Consulting on a Hydroelectric Shaft Exhibiting Flaws
- Weld Failure on Cracked Tube to Tubesheet Welds on Chemical Reactor
- Welding Procedures Used to Attach Appendages to P91 Heavy Wall Pipe
- Structural Analysis & Redesign on a Cracked 1,400 Ton Hydraulic Press
- Design/ Application of Weld Overlay on a Refinery Vessel
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 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’ve resolved issues including:
- Weld Distortion / Cracking
- Weld Failures
- Weld Defects/ Porosity
- Fatigue of Welded Joints
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.
A few examples include:
- Oil/ Gas
- Power Generation
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).

Learn from the experience of others. Especially when one such “other” is Dr. William O’Donnell, PhD, PE, Founder and President of O’Donnell Consulting Engineers, Inc., and ASME “Engineer of the Year” – his 50 years of experience in analysis of components including fatigue and fracture safety evaluations and failure analyses are now comprised in this volume.
If you are interested learning more in Engineering Design, Manufacturing and Construction, as well as Failure Analysis, then this book is a must have!
