Facilities and Equipment
Mechanised and automated variants of the above processes include the following:
- Orbital TIG
- Narrow-gap TIG
- Robotic MIG/MAG and TIG welding/manipulation
- Mechanised MIG and TIG cladding
- Integrated column and boom submerged-arc welding systems
Research and Development
Concepts currently under research through our £4 million per annum Core Research Programme include the following:
- Cold temper bead arc welding in the context of austenitic cladding on ferritic base metal
- Additive manufacturing – generating information for arc-based additive manufacturing (AM) covering materials selection, material properties and microstructure, deposition rate and process economics and reliability
- Weld monitoring – developing a system able to predicting or determining the incidence of defects in real time
The following are examples of successfully completed Core Research Programme projects:
TWI is often a member of consortia conducting publicly funded collaborative projects:
- Clampit: developing a software system to optimise clamping design and welding sequence to minimise distortion
- MARWIN: developing a cognitive computer vision-based welding robot to improve welding efficiency and product quality
- JOINOX: developing empirical user-friendly guidelines to determine fitness for purpose of welded stainless steel surfaces, including effective post-weld cleaning strategies)
- KRAKEN: developing a large additive subtractive hybrid machining system with adaptive control
We develop processes and procedures for specific applications, including feasibility studies (eg powder plasma arc welding) and process comparison and optimisation. We also work closely with equipment and consumables developers to study the viability, benefits and limitations of recently developed technologies.
Consultancy
We provide our Members with guidance on many topics relating to arc processes:
- Selection and application of codes and standards
- Specification, design, consumables and process selection
- Troubleshooting weldability and fabrication issues
- Repair procedure development, methodology and implementation
- Quality assurance and auditing services
- Litigation support and expert witness and arbitration
- Health and safety advice
The above list is not exhaustive; email contactus@twi.co.uk if there is another issue on which you require expertise. More information can be found in our Welding engineering section. For example, you can find out how TWI has been helping assist with the building of Hinkley Point C in Somerset.
Software
- Weldspec – welding procedure software for engineers and managers who track and manage welding procedures
- Welderqual – welder qualification software to manage welder qualifications and enable managers to quickly identify the most suitable individual for a task
- Welding co-ordinator – welding fabrication management software for full site-wide management and traceability of fabrication information
- Welding estimator – a quick and easy-to-use cost estimation tool for welding procedures and projects
