A Welding Procedure Specification (WPS) is a guiding document in any welding quality management program. This workshop will explore that role and guide the participants through the process of writing and qualifying a WPS that is ASME Section IX compliant, metallurgically sound, and meaningful to the welder.

This includes live demonstrations on the welding of the coupon; test specimen location and preparation; tension, bend, and charpy testing; evaluation of the test results; and generation of the procedure qualification record(s) (PQRs) and WPS.

Topics include:

  • What is a WPS?
  • Why are WPSs necessary and who cares about them?
  • How various industries and codes address welding procedure qualification
  • Understanding qualification “variables”
  • What comes first? The WPS or the PQR?
  • What questions does one need to ask to develop a WPS?
  • How to qualify multiple welding processes and/or filler metal classifications using a single test coupon
  • When and how to amend an existing WPS to extend the qualification range(s)
  • Addressing heat-input control for WPSs qualified with toughness
  • Sources for reasonable and meaningful ranges for variables on the WPS
  • Avoiding the common mistakes in WPS qualification

* Registration is limited to 20 students

Qualification of Welding Procedures Conference Schedule




• Registration Open 7:30 am – 5:00 pm
• Sessions 8:00 am – 5:00 pm
• Attendee Lunch noon – 1:00 pm


The workshop will begin with a discussion of the functions served by welding procedure specifications (WPSs), the data they should contain, and why they are an important part of the quality management system for any fabrication shop. Various industries, and sometimes countries, are governed by different codes, most of which have differing qualification rules. This section will also include an overview of the most commonly encountered qualification codes and their differences.

Using Section IX of the ASME Boiler and Pressure Vessel Code, the different categories of variables for procedure qualification will be defined. We’ll explain how to select the base metal, thickness, welding process, filler metal, etc. for qualifying a WPS. We’ll then answer the question, “Which one comes first, the procedure qualification record (PQR) or the WPS?”

As a starting point, we will learn a simple way to read and understand the tables of the essential, nonessential, and supplementary essential variables for the SMAW, GMAW, FCAW, and GTAW processes and we will review the more significant variables for those processes.

We will go into the weld lab and participate in the welding of PQR coupons to support four different process combinations: (1) GTAW + FCAW, 1 ¼ inch thick P-No. 1 plate, with traditional heat input control, (2) GMAW-S (short-circuiting) + GMAW-P (pulsed spray) both with waveform control, ½ inch thick P-No. 1 plate, power/energy heat input control, (3) SMAW using E6010, < 3/8 inch thick P-No. 1 plate, heat input control by volume of weld metal deposited per unit length of electrode, and (4) GTAW corrosion resistant overlay (CRO) of ER309L followed by ER308L on P-No. 1 plate. Attendees will be able to observe how the coupons are marked for specimen removal and the actual removal of the tension, bend, and charpy specimens.



• Registration Open 7:30 am – 5:00 pm
• Sessions 8:00 am – 5:00 pm
• Attendee Lunch noon – 1:00 pm


Attendees will witness the testing of the tension, bend, and charpy specimens. All the test data will be reviewed for code compliance.

PQRs will then be generated from the data obtained as follows: two PQRs will be generated, one with and one without toughness and supplementary essential variables for each of the three groove weld coupons. Students will then use the PQRs to support both single-process and multiple-process WPSs, with and without toughness. A CRO WPS will also be generated. We will discuss and demonstrate the acceptable ranges for the qualified essential and supplementary essential variables.

Using the WPSs generated, we’ll discuss and demonstrate how to amend a WPS to extend a qualification range, the proper use of nonessential variables, and what is meant by “intrinsically addressed variables.” At the conclusion, we’ll discuss some of the common mistakes on WPSs and how to avoid them.

Mike Rice

Mike Rice retired as the Senior Corporate Welding Engineer for Nooter Corporation. A graduate in Welding Engineering from LeTourneau University.

He has been in the welding industry for 39 years.

His first job after graduation was in the R&D laboratory for Newport News Shipbuilding developing an electro slag welding technique to join 11-inch-thick strut arms for aircraft carriers. He also developed and introduced to the shops and ships orbital pipe welding for both nuclear and non-nuclear piping applications. Later he managed the welding activities in the nuclear and non-nuclear pipe shops.

In 1990 he started working for Nooter Fabricators as a welding engineer on various pressure vessel projects and developed techniques for internal tube to tubesheet bore welding and hot-wire plasma arc overlay. As the Chief Welding Engineer, he represented Nooter Fabricators in a joint venture with a company in Malaysia.

In 2002 Mike became the project manager for Bechtel for the Waste Package Closure System at the Yucca Mountain Project. He was responsible for the design and building of a closure system requiring remote welding, NDE and material handling systems.

After completion of the closure system project, he returned to Nooter Corporation as the Senior Corporate Welding Engineer leading the welding programs within the Nooter family.
