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 […]

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 […]

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 […]

Why Welds Crack

A weld failure is never good.  Whether  a weld cracks on a truck’s axle or on the post holding your house’s fence, there are always consequences.  Hopefully the consequences are limited to time and money.  Unfortunately, weld failures can cause injury.   Welds can fail due to design flaws, but the majority of weld failures occur […]

Welding Procedure Specification Variables

A Welding Procedure Specification has several variables which should be carefully specified.  The values selected for the variables discussed below have a significant impact on weld soundness and mechanical properties. It is critical that these values be appropriate for the specific requirements of applicable code and job specifications.  The variables in a WPS are the […]

Welder Certification

One of the most common questions we get on our day to day activities is How can I get may welder(s) certified?  The immediate is response is: Certified on what?  Most manufacturers assume that there is a single certification for which their welders can apply, test and become certified.  Unfortunately this is not the case.  […]
