TIG welding
Carbon-steel and stainless-steel welding supported by welding procedure specifications (WPS). Our procedure records include qualifications to BS EN ISO 15614-1.
Quality & assurance
Skilled people. Responsible delivery.
Welding qualifications, practical safety controls and a commitment to improving how we work — from workshop fabrication to site handover.
Welding procedures & qualifications
Evidence behind the workmanship.
TIG and manual metal arc welding, supported by documented procedures and welder qualification records. We review the applicable coverage against the requirements of each project.
Manual metal arc welding
Our records include a qualified procedure for dissimilar steel fillet welds to BS EN ISO 15614-1, Level 2. The materials, joint details and welding position determine its suitability for the work.
Qualified welders
Our welder qualification records include BS EN ISO 9606-1. Process coverage, material, joint type and continuity records are checked for the person assigned to the job.
Supporting procedure qualification records (WPQR/WPAR), inspection requirements and material traceability are reviewed as part of project preparation. Specialist non-destructive testing can be coordinated where required.
Discuss welding and inspection requirementsHealth & safety
Safe working starts with preparation.
TTN is committed to protecting the people carrying out our work and those working around us. We plan the task, communicate the risks and coordinate with the client before work starts.
Plan the work
Task-specific risk assessments and method statements set out the work sequence and controls. Permits, isolations, access, lifting and confined-space arrangements are agreed where relevant.
Work together
Clear responsibilities, suitable supervision and task briefings help teams work safely around operating plant and during shutdowns.
Respond to change
We encourage people to raise concerns and stop work when conditions are unsafe. Changes to the task or site conditions require the controls to be reviewed before work continues.
Confined-space entry: personnel training records include entry, gas testing, escape breathing apparatus and emergency procedures. Personnel, isolations and rescue arrangements are assessed and agreed for each task.
Workforce skills
The right competence for the role.
Our personnel records include CSCS and CPCS cards, CCNSG safety passports and IPAF operator training. Relevant categories, validity and competence are checked against the task and the site's requirements.
- CSCS Site cards
- CPCS Plant operator cards
- CCNSG Safety passports
- IPAF Access equipment training
These relate to individual personnel and their roles. Trade qualifications and supporting training records can be discussed during project preparation.
Supplier assurance

Specialist services
One coordinated project package.
TTN can include specialist subcontracted services within our provision, coordinating the scope, specification and supporting documentation with the provider.
Structural steelwork
Structural steelwork can be provided through specialist subcontractors to the applicable BS EN 1090 requirements. The execution class and conformity documentation are agreed for the work.
Quality management
Our specialist steelwork provision includes providers with ISO 9001-certified quality management systems. The provider's certification and scope are checked for the package being supplied.
Hot-dip galvanising
Hot-dip galvanising to BS EN ISO 1461 can be included within our fabrication package through specialist subcontractors, with the finish specified to suit the work.
Environmental commitment
Practical steps towards lower-impact working.
We are committed to improving resource use and considering more sustainable ways to deliver our work, alongside safety, reliability and the needs of the site.
Trialling battery power
We have started trialling Instagrid and EcoFlow battery power systems as alternatives to generators for suitable tasks during shutdowns.
Match power to the task
The trials consider equipment demand, operating time, charging arrangements and site conditions to establish where battery power is a practical option.
Learn and improve
Our aim is to reduce reliance on fuel-powered generators where feasible. We will use experience from the trials to guide wider adoption.
From enquiry to handover
Agree the requirements. Keep the records clear.
Tell us about the specification, site controls and documentation your project needs. We will review the scope and agree the appropriate procedures, inspection and handover requirements.
