API 1104 Welding Inspection Services
Need an API 1104 welding inspector for pipeline construction, a repair programme, a tie-in or related facilities?
Dilenza provides API 1104 welding inspection services by matching inspector profiles with relevant pipeline welding and code experience to the actual project requirement: pipe and materials, welding procedure documents, joint type, construction stage, inspection scope, location and schedule.
Use the service for supplier fabrication, field construction, production welding surveillance, defined hold points, repair verification or resident and rotational inspection coverage.
- Inspector profiles matched to API 1104 project requirements
- Scope from one defined hold point to continuous construction surveillance
- Project documents reviewed before profile selection

API 1104 Welding Inspection Services for Pipelines and Related Facilities
API 1104 is used for welding of pipelines and related facilities. It can apply to gas and arc welding for construction and in-service repair where the project documents designate the code.
Dilenza provides independent inspection support against the requirements defined by the project. Before proposing an inspector, the available documentation is reviewed to establish the applicable code edition, project specification, welding processes, inspection points, NDT responsibilities, reporting requirements and schedule.
The controlled project documents always determine the exact inspection scope and acceptance criteria.
What an API 1104 Welding Inspector Can Verify
Before welding begins
- Applicable code, project specification, inspection and test plan and hold points
- Available WPS, supporting procedure qualification records and welder qualification records
- Pipe, material and consumable documentation where included in scope
- Joint preparation, fit-up requirements and welding sequence
- Identification, traceability and reporting arrangements required by the project
During welding and construction
- Joint preparation, alignment, root gap and internal misalignment where specified
- Preheat and welding conditions where included in the approved procedure
- Welding activity against the agreed procedure and project requirements
- Weld identification, production records and agreed inspection points
- Construction-spread, shift or supplier surveillance as defined by the assignment
After welding
- Visual examination against the agreed project requirements
- NDT status, witnessing or record review where included in scope
- Repair observations, reinspection status and repair documentation
- Weld maps, traceability records and final inspection documentation
- Clear reporting of observations through the agreed project process
Any specialist NDT work remains subject to the project-defined method, personnel qualification and responsibilities.
API 1104 Is a Welding Code, Not an Inspector Qualification
API 1104 defines welding and inspection requirements. It does not, by itself, specify the inspector’s personnel credential.
The project may require an AWS CWI, CSWIP, International Welding Inspector, NDT-qualified professional or another defined profile. Dilenza therefore reviews the stated qualification alongside proven experience with comparable pipeline welding, project documents, materials, welding processes and inspection responsibilities.
The right profile is selected for the assignment, not simply for the code name.
Pipeline Experience Matters as Much as Code Knowledge
An inspector with general fabrication experience may not be the right fit for a pipeline assignment. API 1104 inspection can involve different work fronts, construction schedules, weld tracking, field conditions and coordination with NDT activities.
Before proposing a profile, Dilenza considers:
- Pipeline construction, repair, tie-in or related-facility experience
- Comparable pipe diameter, wall thickness, materials and welding processes
- Field construction, supplier fabrication or station-work environment
- Project requirements for weld mapping, traceability and reporting
- NDT coordination, repair follow-up and inspection-point responsibilities
- Location, working pattern, rotation, language and availability
One Hold Point, Recurring Surveillance or Resident API 1104 Inspection
One defined inspection visit
For a specific fit-up check, weld inspection point, NDT witness point, repair verification, document review or final release activity.
Recurring welding surveillance
For repeat attendance during a construction campaign, supplier fabrication programme, pipeline repair project or defined production stages.
Resident or rotational pipeline inspection
For continuous field construction, a long-duration repair programme or multiple work fronts. The assigned inspector can follow agreed activities across shifts, construction spreads or project phases.
What You Receive From an API 1104 Welding Inspection Assignment
- A review of the available scope before profile selection
- An inspector profile matched to the specified qualification and relevant pipeline experience
- Confirmation of agreed inspection activities and reporting requirements
- Inspection reports and observations in line with the agreed assignment
- Traceability, weld-record or repair-status review where included in scope
- Clear escalation of issues through the agreed project communication process
Independent API 1104 Inspection for Suppliers, Field Construction and Repairs
Dilenza provides third-party inspection and reporting support. The service does not replace the project engineer, design authority, specialist NDT personnel or the contractor’s own quality-control responsibilities.
Dilenza does not design pipelines, approve or modify welding procedures, certify welders or issue project acceptance on behalf of the owner. Any authority must be defined explicitly in the contract and project documentation.
Assignments can be reviewed for suppliers, fabrication workshops, pipeline construction areas, tie-ins, repair locations, stations and other related facilities.
API 1104 Welding Inspection Services FAQ
What are API 1104 welding inspection services?
They are third-party welding inspection services for projects where API 1104 is part of the controlled requirements. The assignment can cover document verification, welding surveillance, visual inspection, NDT coordination within scope, repair follow-up and reporting.
Is API 1104 an inspector certification?
No. API 1104 is a welding code. The required inspector credential must come from the project specification, together with relevant pipeline welding and code experience.
Can we request an inspector with API 1104 experience?
Yes. Include the controlled project documents, pipeline or facility scope, welding processes, required qualification, location, dates and expected duration. Relevant experience can then be reviewed during profile selection.
Does the welding inspector perform NDT?
Not necessarily. Welding inspection and NDT are distinct activities. Where the project requires it, the inspector may witness NDT, review its status or coordinate records within the agreed scope. Specialist NDT must be performed by appropriately qualified personnel.
Can Dilenza support pipeline repair and tie-in work?
Yes, subject to the available project requirements, site conditions and suitable inspector availability. State whether the scope concerns construction, a repair, a tie-in or another project phase.
What documents should we send?
Send the available API 1104 reference, welding specification, ITP, WPS, welder qualification records, drawings, weld map, NDT plan, location, dates and expected inspection duration.
