Welding & Mesh Products
R-TECH Materials has accredited testing of all standard tests on welded fabric, including:
- Tensile testing
- Weld shear testing
- Rebend testing
- Fatigue testing
- Rib geometry measurement
- Chemical analysis
Welded prefabrication of reinforcing steels has increased significantly in the last ten years because of the benefits of faster site construction times. Welded fabrications may be for beams or piles, or may be bespoke products such as roll mats.
In order to ensure that welding is being conducted in a controlled way, without detriment to the material properties, test welds must be produced and tested. Each welder must also be tested to ensure that they have the required skill to produce welds to the required standard. Welds can be tested to the requirements of BS 7123 (now obsolete) ISO 17660 or other national standards. R-TECH Materials is also able to test welds to the requirements of the CARES scheme Appendices 6 (for locational welding) and 10 (for structural welding).
R-TECH Materials offers all tests on welded reinforcing steels required for the approval of weld procedures and welder qualifications tests. In addition to test reports, approval certificates are issued showing the range of approval according to international standards.
Standard tests include the following:
- Tensile tests
- Macro examination
- Weld shear tests
- Hardness tests
- Bend tests
R-TECH Materials is also able to provide consultancy assistance for welding of reinforcing steels:
- Advice on welding procedures
- Advice on quality management systems for welding
- Investigation of welding problems
- Failure analysis of welds
