Who needs welding procedures?
Code work requires written welding procedures. This is generally found in bid documents,
structural drawings general notes, and the job specifications. They show your customer that you have the ability to perform
the welding work. A copy should always be kept near the ongoing work as these are the welders instructions.
A WPS is a "Welding Procedure Specification" or "Welding Procedure" as it is commonly called. It contains the combination
of variables used to make a certain weld. This includes the process (SMAW, FCAW etc.), the electrode type, electrical characteristics,
base metal used, preheat and interpass temperatures, travel speed and position, post weld heat treatment, shielding gas and
flow rate, and the type of joint being welded.
What does Pre-Qualified mean?
Welding codes sometimes require a
qualification process (by testing) for certain welding procedures so the contractor can demonstrate to the engineer/owner
that he fully understands what has to be done. Pre-Qualified Welding Procedures use known variables that have a long history
of making a sound weld and require no testing. A written procedure is required in both cases. Weldingprocedures.com carefully
reviews the code requirements to insure that our procedures meet the Pre- Qualified status. If the work you are doing requires
testing, we will let you know what you need to do.
What is a PQR?
A PQR is a "Procedure Qualification Record".
This form is used when a welding procedure is qualified by testing. A WPS "Welding Procedure Specification" is also used and
the two documents reference each other. The WPS describes how the weld was made and the PQR describes what testing was used
to qualify the weld using a welding code guidelines such as AWS D1.1. If the weld is "Pre-Qualified" by meeting the requirements
of a code, then no PQR is needed.
What is a CWI?
The American Welding Society has an inspector certification program
for welding inspectors. An inspector who has the required experience and passes the AWS exam becomes a "Certified Welding
Inspector" or CWI. For more information on this program contact AWS.
