Understanding Welding Codes and Procedures

Understand welding codes from AWS and API, their scope and reading rules, and learn to implement compliance requirements into WPS and PQR with practical guidance.

Explore codes, standards, and specifications governing welding, including welding procedure specifications, procedure qualification records, and welder qualification records, and understand document hierarchy and precedence.

Understand governing welding documents, including woops, pqr, and wpq, and how codes reference them while addressing essential versus nonessential variables and flexible formats.

Document the procedure qualification record to qualify the welding procedure specification, record essential variables and lab test results, and note welder qualification validity and ASME/AWS code requirements.

Explore welding codes and standards and specifications from AWS, ASME, API, ANSI, ABS, and DoD, and see how these guide materials, design, and safety for boilers, vessels, and ships.

Understand ASME section nine, the welding, brazing, and fusing qualification code, covering procedure and performance qualifications, material scope, and how AWS standards compare with API, ABS, and military specs.

Explore key welding codes from the American Welding Society and ASME, including B31 piping and ASME sections for power boilers, materials, welding rods, nondestructive examination, design, and testing.

Explore welding codes for carbon steel, aluminum, and reinforcing steel, including prequalified procedures and codes such as D1.1, D1.2, bridge welding, reinforcing steel welding, and API 1104.

Explore welding codes and procedures, define a welding procedure specification (piece) and a procedure qualification record (PQR), and explain destructive testing of test coupons to verify mechanical properties.

Identify essential and supplementary essential variables in welding procedure specifications, understand PQR basics, F numbers, and non-essential variables, and recognize impact testing and the ductile-to-brittle transition.

Discover how welding codes become two key documents, the welding procedure specification and the procedure qualification record, detailing inputs like base material, filler, electrical characteristics, shielding gas, and test results.

Explain how supplementary essential variables affect toughness properties in weld joints, including the ductile-to-brittle transition, triggering requalification when construction codes require impact testing.

Explore supplementary essential variables in ASME section nine, including P-number groupings, filler metal diameter, heat input, impact testing, and welding position requirements that drive requalification.

Understand what a pwps is and why it matters for procedure qualification records, outlining test coupon work instructions, materials, essential variables, and client review.

Specify essential and supplementary variables in the pre welding procedure specification and work instructions for a weld test coupon, including voltage, amperage, preheat, filler metal, and cleaning.

Learn to identify welding requirements and select processes, then develop a PQR under ASME codes, detailing required tests and supporting documents such as MTRs or certificates of conformance.

Learn how to use PQR methodology to qualify welding procedures, from essential variables and test coupons to visual inspection and NDE testing, guided by ASME Section IX and ORS codes.

Explore welder performance qualification, essential variables, and the separation between welding procedures and personnel, using visual, radiographic, and mechanical tests to verify sound welds.

Outline welder performance qualifications, detailing essential variables, F numbers, positions, backing, tests, and radiography requirements for certifying welders.

Explore welder performance qualification through plate and pipe test coupons, and verify weld soundness with bend tests and macro examinations, complemented by potential non-destructive testing.

Explain welder continuity under the used 1.1 structural welding code, detailing period of effectiveness, six-month usage thresholds for validity, expiration and renewal, retest, and record-keeping.

Learn how qualification expires after a six-month period of not welding with a process, how renewals and revocations work, and how to maintain continuity logs.

Explore the guided bend test for welding procedures, including jig types, mandrel sizes, material-specific dimensions, and acceptance criteria across ASME section codes to assess weld ductility.

Conclude your study of welding codes and procedures with lifetime access to all course materials and an invitation to engage with instructors for ongoing skill advancement.
