Specialised On-Site Welding Services
Addressing structural fatigue or failure in steel structures is a core expertise of BS Steels’ welding services. It is also a highly technical challenge, requiring careful analysis, creative solutions and close cooperation with contractors and specialised partners in areas such as testing, laboratory services, welding technology and documentation.
Through its work on repairs to the motorway and highways network in particular, BS Steels has a team, knowledge base and network of contacts enabling it to take on the most challenging welding tasks.
BS Steels’s partnership ethos, proven extensive experience in highway, railway and industrial repairs, and EXC3 and NHSS20 certifications, make it the ideal partner wherever structural fatigue or failure needs to be addressed, or remedial welding is required. Our specialist teams are available to tackle projects across the country.
BS Steels will apply whatever techniques are appropriate to the situation: these include MAG welding, pulse MAG welding in a wide range of positions and thicknesses, TIG, Plasma, Plasma dressing. Great attention to detail is given always to control of heat and gas, speed and depth of welds to achieve the correct fusion of materials.
In addition to complex on-site welding assignments, BS Steels is always ready to take on smaller and medium-sized projects in its workshops.
Welding Expertise in Action: M25 Gade Valley Viaduct
Working with Highways England, Connect Plus and Osborne, BS Steels has been engaged in strengthening the welds on the underside of the viaduct spans on the Gade Valley Viaduct, by Junction 20 of the M25.
BS Steels delivered a dedicated team, continuously on site. Remedial works were carried out under ten spans of the viaduct.
BS Steels was involved throughout, interpreting engineering designs, manufacturing the strengthening plates, and executing all welding, drilling and bolting. In total, 2,349 strengthening plates were installed, using 37,238 TCB bolts. 273 plasma weld dresses were made, totalling well over a kilometer of welds!
Great care was taken to provide the right conditions for welding and for personnel. Particularly innovative was the setting up of a robotic system within the welding box – highly unusual in on-site conditions.
