How To Qualify A Welding Procedure

Whenever you hear that a welding procedure needs to be qualified it simply means that its suitability for use in a welded structure needs to be proven by testing. This means that the welding procedure must be capable of producing sound welds.  But what are sound welds?  Sound welds are welds that will perform in […]

Importance of Weld Failure Analysis

Basic guidelines to troubleshoot weld failures

When a weld fails we don’t always know what caused it.  We may try something different and if it doesn’t fail the next time we adopt that as the new standard.  However, it is very important to know the root cause of weld failures.  If we don’t know what caused the failure how can we […]

7 Tests to Qualify Welding Procedures

The qualification of welding procedures is necessary to ensure that the selected welding parameters can produce sound welds.  Qualification typically involves a combination of destructive and nondestructive testing.  When a particular code, such as AWS D1.1 or ASME Section IX is used, the code will dictate the type and numbers of tests necessary in order […]

5 Building Blocks of a Weld Quality Control System

Controlling weld quality is not always an easy task.  Many fabricators struggle to manage the amount of rework, the discrepancies from one batch of product to the next, and the varying levels of productivity and workmanship amongst their welders.   This inability to control weld consistency is not surprising.  Welding has more than 20 variables that […]

Why More Customers are Requiring Qualified Welding procedures

If you own or work at a job shop you may have noticed an increase in the number of customers that require the use of qualified welding procedures to build their products. Some fabricators are even getting this request from long time customers who never required them in the past. So why is this? The […]

Etching Solutions for Steel, Stainless, Aluminum and Other Metals

For high-quality macro-etches

The qualification of welders and welding procedures often involves macro-examination of welds.  Performing macro-etches is a relatively simple procedure, but strict guidelines must be followed to ensure safety.  Most chemicals used in etching solutions are hazardous and must be handled accordingly.  Any person etching with these chemicals must  familiarize him or herself with the corresponding […]

The 9 Clauses of AWS D1.1 Structural Welding Code Explained

The most widely used welding code in North America, and perhaps the world, is AWS D1.1/D1.1M Structural Welding Code – Steel.  It is specified as the quality standard in hundreds of contract documents every year.   Yet, we find that less than half of the fabricators that need to use it have a sound understanding of […]

The Importance of Accurate Documents to Support Welder Qualifications

When it comes to precision welding and fabrication, it only takes one wrong document to cause a major problem.  Still, many companies operate by the motto: “if it ain’t broke, don’t fix it”.  Assuming you have incredible attention to detail and a lot of luck, that approach might work for a while.  That’s why companies […]

Who Can Qualify My Welders?

There is a misconception in our industry that the qualification of welders, and welding procedures for that matter, needs to be done by a certified welding inspector (CWI) or a welding engineer.  Or that it has to be done by a third party.  Although this may be the case if specified in contract documents, more […]
