Welding Capabilities
- Welding specification and procedure development for an extensive range of materials.
- Input to the design and constructability of offshore structures, pipelines and chemical plants from preliminary design through to support of the construction team.
- Advice during design on the weldability of materials, welding design, fracture toughness design criteria and the extent of pre and post-weld heat treatment.
- Conducting technical bid assessments of manufacturers and fabricators.
- Development of material and fabrication specifications.
- Determining allowable defect acceptance criteria API 1104 Section 9 or Appendix A or ECA in accordance with BS 7910, FLAWPRO or DNV/SINTEF guidelines
- Specialized testing, single edge notch tension (SENT)
- Assisting with setting up and managing weldability testing requirements in accordance with API RP 2Z. This weldability data details the response of materials such as line pipe and forgings to thermal cycles, in the heat affected zone of welds, in terms of hardenability, fracture toughness, or softening.
- Pre and post weld measurement including use of TOFD for go/no go check on completed welds.
- Weld alignment including machining, measuring and sorting of line pipe.
- Technical audits of vendors or fabricators.
- Review of vendors or contractors welding, fabrication and non-destructive testing documents.
- Assignment to fabrication, construction and installation sites to co-ordinate fabrication activities.
- Evaluation of weld and heat affected zone microstructures.
- Assessment of failures and rectification and prevention strategies.
- Ensure the quality of all welding operations used in onshore and offshore fabrication, through identifying appropriate welding procedures, welder qualifications and inspection and test methods.
- Ensuring compatibility between weld metal and base material for piping systems for corrosive hydrocarbons.
- Weld overlay requirements for crevice corrosion prevention taking into account, maximum iron content permitted, corrosion resistant alloys and minimum thickness requirements.
- Validate fabrication and construction by NDE methodologies including automatic ultrasonic testing.
- Serve as a technical expert in contractual matters between purchaser and contractor
- Specify the minimum requirements for welding operations which will be subject to third party verification / certification
