Welding Consultation and Engineering Services

Monday, May 12, 2014


We are now offering Welding Engineering Consultation Services, as well as a Certified Welding Inspector (CWI).  Our certified welding inspector has over 35 years of industrial welding experience and is certified by the American Welding Society (AWS), which enables us to assist you with the following services:
  • Complete contract review of an welding project to include: documentation review of project requirements, determination of CWI requirements and reporting requirements
  • Qualification of Welders
  • Ensure compliance with AWS and ASME codes and standards
  • Solve quality issues by determining the source(s) of welding defects and providing solutions reducing rework and overall costs
  • Development of Welding Procedure Specification (WPS), Procedure Qualifications Record (PQR), and Welder Performance Qualificationensuring weldment conformance and integrity
  • On-site inspections


Why is Weld Inspection Important?

To ensure quality welds, it is imperative that a company have a quality weld inspection program in place. In order to do so, there must be a welding inspector capable of evaluating weld characteristics, determining weld quality and performing a number of different testing methods.

There are quite a few reasons why one should inspect a weld; however the most fundamental reason is to determine whether its quality is good enough for its intended purpose. In order to evaluate a weld there must be a form of measurement to compare its characteristics and a qualified individual to perform the evaluation. Evaluations of weld characteristics includes the size of the weld and the presence of discontinuities. The size tends to be extremely important  and often correlates directly with strength and performance. If a weld is undersized it may not withstand the stresses applied during use. Oversized welds also produce stress points and can distort the welded component when in use. 

Discovering weld discontinuities is another important factor when determining quality of a weld. Iperfections within a weld or an adjacent weld can prevent the weld from meeting its intended function. When welding discontinuities are of an unacceptable size or in the wrong location, they are referred to as welding defects and cause premature weld failure by producing stress and pressure points within the welded component.

What Are The Weld Inspectors Responsibilities?

Weld inspection requires knowledge of weld drawings, symbols, design, techniques, procedures, etc. Thus, a welding inspector must be formally qualified or have the necessary knowledge and/or experience to conduct the inspection. A welding inspector should be well-versed in the following topics and procedures in order to perform proper weld inspection.
  1. Welder Performance and Welding Procedure Qualification.
  2. Visual Inspection. 
  3. Surface Crack Detection.
  4. Radiographic and Ultrasonic Weld Inspection. 
  5. Destructive Weld Testing.
  6. Interpretation of Welding Details and Weld Symbols. 


Qualification Details

Being qualified by the American Welding Society (AWS) requires strict qualifications and examinations. Learn more about the certification qualifications and its process at https://www.aws.org/w/a/certification/CWI/
