5 Types of Tests for Welder Performance Qualification

Codes detail the requirements for performance qualifications of welders, welding operators and tack welders. Many codes do not demand that a Certified Welding Inspector (CWI) or a welding engineer conduct the necessary testing.  Unless your customer specifically asks that a CWI or third-party do this, you can simply follow the code yourself to perform all […]

Benefits of Using Prequalified Welding Procedures

Prequalified welding procedures are a great tool available to those who need qualified procedures in conformance with  AWS D1.1 Structural Welding Code – Steel.  However, there are strict requirements for the use of a prequalified welding procedures.  It is not as easy as picking a qualified joint and using filler metal manufacturer’s recommended procedures. There […]

Preventing Hydrogen Induced Cracking

Our last post (Factors Influencing Hydrogen Induced Cracking) went over the factors that contribute to hydrogen-induced cracking.  We will now go over how to prevent HIC from happening.  If you recall, we mentioned you need all three factors to be present in order to have HIC:  These factors are 1. a susceptible microstructure, 2. threshold […]

7 Ways You Are Violating Welding Procedures And Don’t Know It

Good intentions are not enough - Check Everything!

Some welding shops can weld however they want and don’t have to comply to any  standard or code.  On the other hand, some manufacturers have to meet and follow stringent requirements  and follow specific codes such as AWS D1.1, API 1104 or  ASME Section IX.  The development of welding procedures is not an art, at […]

What Changes To A WPS Require Requalification

Normally the posts on our blog are inspired by questions frequently asked by customers.  Unfortunately, the question above is not asked that often, but it should be.  A welding procedure specification (WPS) is a set of instructions that if followed to the letter, insure a sound weld.   A WPS will typically provide ranges rather than […]

Understanding Weld Discontinuities

Not all discontinuities are defects

Not all weld discontinuities are weld defects, but all weld defects are discontinuities. Understanding the difference will let you know if you need to scrap a part, repair it or simply add more weld. There are many codes depending on what type of product you are welding on. The codes are used as guidelines by […]

Tips for Passing the AWS 3G FCAW Certification

Passing the AWS Structural Welder Qualification Test (vertical up certification on Flux-Cored Arc Welding) can be problematic for some, but insuring the right procedures and techniques  are used should make things a lot easier.  The good thing about this qualification is that if passed it certifies the welder no just in the 3G position, but […]

Proper Use of Weld Gages

In the January 2011 AWS publication of Inspection Trends, Albert J. Moore Jr. states that “other than the measuring tape, the fillet weld gage is the most used measuring device in the welding inspector’s kit.” We agree with this statement, but are also convinced that the fillet weld gage is THE most underused tool by […]

How to Become a Certified Welding Inspector

A career as a Certified Welding Inspector (CWI) can be very rewarding.  This certification, which is awarded by the American Welding Society, carries a lot of weight both nationally and internationally.  The main responsibility of a CWI is to make sure that welders follow specified guidelines in order to manufacture a product that is of […]
