Piping & Engineering: Production Welding in piping

Poduction welding in piping

1. Welding processes

- Manual, semi-auto, mechanized/machine/automated
- Consumables : filler metals - gas

2. Productivity

- Criteria/tools: materials - dia/thickness ranges – workshop/field – design codes/acceptance criteria
- Selection of joint types, processes, filler metals and gas
- New developments e.g. EBFlow, Rotoweld, K-TIG etc.

3. Quality

- Standards: ISO 9001/3834
- WPS/PQR-WPQ
- Monitoring/inspecion (before-during-after)
- NDE and SPC (Statistical Process Control)
- Technical audit

4. Heat treatments

- Furnace/local
- Recording:reporting
- Pitfalls
- Standards

5. Dissimilar Metal Welds

- Types
- Methodologies: selection process and filler metals

6. Quality Assurance

- Certification/qualification/calibration/validation: materials, personnel, equipment
- Traceability
- Databook production welding
