Aramco SAES-W-011 Welding Standards: What Every QC Inspector Must Know
By SkillJet Editorial Team · August 10, 2026
If you're targeting QC inspector roles in the GCC — particularly with Saudi Aramco or its contractors — you need to know SAES-W-011. This is Aramco's Engineering Standard for Welding, and it's one of the most frequently referenced client specifications in the Middle East oil and gas sector.
SAES-W-011 doesn't replace ASME or API codes — it overlays them with additional, often stricter requirements. Understanding how it works is the difference between being hired for Aramco projects and being passed over.
What Is SAES-W-011?
SAES-W-011 is the Saudi Aramco Engineering Standard that governs welding on all Aramco projects. It covers:
- Welding procedure specifications (WPS) and procedure qualification records (PQR)
- Welder performance qualifications (WPQ)
- Base metal and consumable requirements
- Pre-heat and post-weld heat treatment (PWHT)
- NDE requirements and acceptance criteria
- Inspection and documentation requirements
The standard applies to all welding on Aramco facilities — pipelines, pressure vessels, structural steel, storage tanks, and piping systems. It's referenced in every Aramco welding-related ITP (Inspection and Test Plan).
How SAES-W-011 Overlays ASME and API Codes
The key concept: SAES-W-011 uses ASME B31.3, ASME Section IX, and API standards as the base, then adds Aramco-specific requirements. Here's how it works in practice:
| Area | Base Code (ASME/API) | SAES-W-011 Addition |
|---|---|---|
| WPS qualification | ASME Section IX | Aramco-approved consumables only; additional testing may be required |
| Welder qualification | ASME Section IX | Must be qualified to Aramco-approved procedures; Aramco maintains a database of approved welders |
| NDE extent | ASME B31.3 (spot/random) | Often 100% RT for critical service lines; extent specified by line class |
| Acceptance criteria | ASME B31.3 Table 341.3.2 | May be stricter — e.g., zero porosity for certain services |
| PWHT | ASME B31.3 Table 331.1.1 | Additional thickness/temperature requirements for specific materials |
| Pre-heat | ASME B31.3 | Minimum pre-heat temperatures specified by material group and thickness |
Key Requirements Inspectors Must Know
1. Consumable Control
SAES-W-011 specifies approved welding consumables by brand and classification. You can't use a generic E7018 — it must be an Aramco-approved brand with proper batch traceability. Inspectors must verify consumable certificates against the approved list and check storage conditions (rod oven temperature for low-hydrogen electrodes).
2. Welder Qualification Database
Aramco maintains a database of approved welders. Each welder has a unique stamp number. The inspector must verify that each welder is qualified for the specific procedure and position being welded, and that their qualification is current. Welder stamps must be verified at the weld — the stamp is the traceability link.
3. NDE Extent by Line Class
Aramco classifies piping into line classes based on service severity. The NDE extent is specified per line class:
- Critical service (toxic, high-pressure): 100% RT + 100% UT (in some cases)
- Normal service: 100% RT for butt welds (stricter than ASME B31.3)
- Low-risk service: Spot RT (10-20%) per Aramco specification
The inspector must read the line class designation on the isometric drawing to determine the required NDE extent.
4. PWHT Requirements
SAES-W-011 specifies PWHT requirements that may differ from ASME B31.3:
- For P-No. 1 (carbon steel), PWHT may be required at lower thicknesses than B31.3
- For Cr-Mo alloys (P-No. 4, 5), PWHT is mandatory with specific temperature ranges
- PWHT temperature and time must be recorded on charts (thermocouple recordings)
5. Hydrotest Requirements
Hydrotest pressures and durations per SAES-W-011 may exceed ASME B31.3 minimums. The inspector must verify:
- Test pressure matches the line class specification
- Test duration is sufficient (typically 1–4 hours depending on volume)
- Test medium (water with specific chloride limits for stainless steel)
- Pressure chart recording
Common Inspection Points on Aramco Projects
As a QC inspector on an Aramco project, your daily inspection checklist will include:
Pre-Weld
- WPS is Aramco-approved and current
- Welder stamp verified against qualification database
- Consumables are from approved list, properly stored
- Pre-heat temperature verified (infrared thermometer)
- Joint preparation and fit-up within tolerance
During Welding
- Interpass temperature within WPS range
- Welding parameters (amps, volts, travel speed) within WPS
- No arc strikes outside the weld zone
- Proper cleaning between passes
Post-Weld
- Weld visually inspected per SAES-W-011 acceptance criteria
- PWHT performed if required (chart reviewed)
- NDE performed per line class (RT, UT, MT, PT)
- NDE reports reviewed and accepted
- Weld map updated with welder stamp, NDE result, and acceptance
Documentation
- Weld map complete with all weld IDs
- WPS/PQR/WPQ records on file
- Consumable certificates on file
- NDE reports filed and traceable
- PWHT charts filed
- Hydrotest package complete
How SAES-W-011 Affects Your Exam Preparation
If you're preparing for the SkillJet.co welding and piping simulator, several questions include client specification overlays (SAES-W-011, ADNOC AGES). These questions test your ability to apply both the base code (ASME B31.3) and the client overlay simultaneously — exactly what you'll face on Aramco projects.
The code reference drawer in the simulator shows the actual SAES-W-011 acceptance criteria during practice, so you can learn to navigate the standard efficiently.
Tips for Getting Aramco-Approved
- Hold the right base certifications — AWS CWI, API 570, or CSWIP 3.1 are typically required.
- Document your experience — Aramco requires verified experience records with employer references.
- Study SAES-W-011 thoroughly — The technical evaluation tests your knowledge of the standard.
- Understand the line class system — Know how to read line class designations and determine NDE requirements.
- Practice with the SkillJet.co simulator — The welding and piping final exam includes SAES-W-011 overlay questions that mirror Aramco's technical evaluation.
The Bottom Line
SAES-W-011 is not optional knowledge for GCC-based QC inspectors — it's a core competency. Aramco is the largest oil producer in the Middle East, and their projects require inspectors who understand both the international codes and the Aramco-specific overlays. Mastering SAES-W-011 opens doors to the most lucrative inspection roles in the region.
Start practicing today with the SkillJet.co welding simulator, which includes SAES-W-011 overlay questions alongside ASME B31.3 and API 570 content. When you can consistently pass the final certification mock exam, you're ready to pursue Aramco-approved inspector status.
Frequently Asked Questions
What is SAES-W-011?
SAES-W-011 is Saudi Aramco's Engineering Standard for Welding. It specifies requirements for welding procedures, welder qualification, materials, inspection, and testing that go beyond the base ASME and API codes. It applies to all Aramco construction, maintenance, and modification projects involving welding.
How does SAES-W-011 differ from ASME B31.3?
ASME B31.3 is the base code for process piping. SAES-W-011 is a client-specific overlay that adds Aramco's additional requirements — stricter acceptance criteria, specific welding consumable requirements, mandatory NDE extents, and Aramco-approved welder/procedure qualifications. When working on Aramco projects, both ASME B31.3 and SAES-W-011 apply simultaneously.
Do I need to be Aramco-approved to work as a QC inspector on Aramco projects?
Yes. Saudi Aramco maintains an approved inspector list. To be approved, you typically need recognized certifications (AWS CWI, API 570, CSWIP), documented experience, and successful completion of Aramco's vendor/inspector approval process. Being SAES-W-011 knowledgeable is essential for passing Aramco's technical evaluation.
What NDE extent does SAES-W-011 typically require?
SAES-W-011 often requires 100% radiographic examination of butt welds in critical service, compared to the spot radiography (5-20%) that ASME B31.3 might allow for normal fluid service. The exact extent depends on the pipe class, service severity, and line category specified in the project drawings.
