So your boss has dropped a stack of welding paperwork on your desk and said review and sign off on these WPSs and PQRs. And your thought is where do I start? Or maybe you new to the Certified Welding Inspection game and are wanting a little bit of insight into how to review WPS/PQRs and Welder Performance qualification records.

There is often a great deal of confusion when it comes to the review of documents for welding and fabrication, such as Welding Procedure Specifications (WPSs) and Procedure Qualification Records (PQRs). The goal of this seminar is to provide insight into the documentation review cycle and detail how to review WPSs, PQRs, and WQTRs as well as provide meaningful feedback in the process.

Attendees that complete all four webinar sessions and earn passing scores on the module exams and the final exam will earn 6 PDHs or 0.6 CEUs.


This course will piggy back on the discussions of welding processes in “Arc Welding Process Overview”. Where we discussed five of the more commonly used welding processes, SMAW, FCAW, SAW, GMAW and GTAW. It is appropriate that discussions of weld filler metals be restricted to those filler metals used with the five referenced processes. We will also limit our conversations to 1) Mild and alloy steels 2) Austenitic and Duplex Stainless Steels and 3) Nickel alloys.

This course will delve into the basic description of the principles of some common arc welding processes and discuss some details of the processes most frequently used in construction manufacturing. 

SMAW, FCAW, SAW, GTAW, GMAW

“Introduction to Metallurgy” covers the basic theories metallurgy for those who are looking for to develop a basic understanding of metallugry. After this course the student will be able to explain the concepts of stress and strain in metals. Describe the different properties of metals.

This course is a course for those who want to know more about how to read welding symbols. AWS A2.4:2012 Standard Symbols for Welding, Brazing, and Nondestructive Examination is the document that is used in North America to define welding symbols. This online course uses instructor voice over and power point presentations to provide instruction that will help the student understand basic welding symbols. Introduction to Welding Symbols is a great start for those who want to understand the hidden language of welding symbols.

Gas tungsten-arc welding is basically a form of arc welding; however, in gas tungsten-arc welding, the electrode is used only to create the arc. The electrode is not consumed in the weld as in the shielded metal-arc process. The gas tungsten-arc welding process generally produces welds that are far superior to those produced by metallic arc welding electrodes. Especially useful for welding aluminum, it also may be used for welding many other types of metals. The GTA process is most effective for joining metals up to 1/8 inch thick, although you can use it to weld thicker material.

In submerged arc welding (SAW), a continuous wire electrode is fed into a mound of granular flux that covers the joint. The welding head is traversed mechanically along the joint and flux is added continuously. The arc causes the base metal, electrode, and flux in the immediately vicinity to melt. The malted base material and filler flow together in the joint. At the same time, the melted flux floats on the surface, forming a protective slag. Since the arc runs beneath the flux covering without sparks, smoke, or flash, the operator needs little protective equipment.
“Introduction to SMAW” covers the basic theories of Shielded Metal Arc Welding for those engineers who are seeking to expand their knowledge of welding processes.

SMAW also known as "Stick" Welding is a welding process that uses a flux coating to shield and protect the liquid weld pool from contamination. SMAW is the most common arc welding processes on the planet due to its versatility, affordability, and suitability for welding a wide variety of metals.

After taking this online course - civil, mechanical and other engineers will have a greater understanding of the SMAW process and will better understand the welding processes strengths and limitations.

“Introduction to FCAW” covers the basic theories Flux Cored Arc Welding (FCAW) for those engineers who are seeking to expand their knowledge of welding processes.

Flux cored arc welding, or FCAW, evolved from the gas metal arc welding, or GMAW process to improve arc action, metal transfer, weld metal properties, and weld appearance. The heat is provided by an arc between a continuously fed tubular electrode wire and the workpiece. The major difference is that FCAW utilizes an electrode very different from the solid electrode used in GMAW. In fact, it is closer to the electrodes used in shielded metal arc welding, or SMAW or stick welding, except the flux is on the inside of a flexible electrode instead of on the outside of a very stiff
electrode.

After completion of “Intro to FCAW” the student should have a greater understanding of the FCAW process.


“Introduction to GMAW” covers the basic theories Gas Metal Arc Welding (GMAW) for those engineers who are seeking to expand their knowledge of welding processes.

Gas metal arc welding (GMAW), sometimes referred to by its sub-types as metal inert gas (MIG) welding or metal active gas (MAG) welding, is an electric arc welding process where the heat for welding is produced by an arc between a continuously fed, consumable filler metal electrode and the work. The shielding of the molten weld pool and the arc is obtained from an externally supplied gas or gas mixture.

After completion of “Intro to GMAW” the student should have a greater understanding of the GMAW process.
