Thermic Lancing was developed after the second world war to remove the heavy concrete structures that littered Europe's coastlines. It is still a very useful tool for companies who need to remove and modify heavy bridge structures. Dangerous and awkward to handle to the untrained, appropriate safety equipment is mandatory. MEG is one of the few centres providing an in depth training course with skilled and experienced instructors.
MEG can also supply thermic lances of differing diameters
Our Welding Engineers and Technologists prepare these to British, European, American and Railway Group standards. The service provides documentary evidence to satisfy your customers and third party insurance organisations.
Using our workshop facilities, we are able to develop procedures which are both practical and consistently reproducible. Whether you require just one procedure or a complete set, our engineers will ensure optimum coverage to suit all your applications.
All procedures and welder approvals are third party accredited and are accepted by all construction and pressure vessel acceptance bodies.
MEG provides a total solution which includes prompt response to all enquiries, with repairs completed at our headquarters in Derby or at sites throughout the UK.
We offer the choice of either undertaking the repair in the most cost-effective way or advising on and supervising the repair work carried out by your own staff.
Whatever the choice, we provide a written technical report containing commentary, welding procedure, photographic record of repair stages and if applicable photo macrograph of the joint type.
All practical work undertaken by MEG includes the following:
Compliant WPQR in accordance with BSEN 15614
Welder fully qualified in accordance with BSEN 9606 for the type and scope of work required
Full and complete Non destructive testing report at repair conclusion (Magnetic Particle Inspection if ferrous and Dye penetrant if non ferrous).
Full technical repair report
Reinforcing steel bars are produced by a number of process routes and usually have a ribbed profile. MEG are approved and certificated to undertake welder approvals and to develop, formulate and approve welding procedures in accordance with BS EN 15614. MEG are well positioned to provide support, welding procedures and welder qualification testing in accordance with the following standards:
BSEN 17660-1: Welding of Reinforced steel:Load Bearing welded joints; applicable to the welding of weldable reinforcing steel and stainless reinforcing steel of load-bearing joints, in workshops or on site. It specifies requirements for materials, design and execution of welded joints, welding personnel, quality requirements, examination and testing.
BSEN 17660-2: Welding of Reinforced steel: Non load bearing welded joints; covers welded joints between reinforcing steel bars and other steel components, such as connection devices and insert anchors, including prefabricated assemblies.
BS 8548:2017 Guidance for Arc Welding of reinforcing steel
BSEN 7123: Metal Arc welding of steel for concrete reinforcement (withdrawn).
BS EN 15614: Specification and qualification of welding procedures for metallic materials: welding procedure test
BS EN 9606: Qualification testing of welders – Fusion welding
BS EN ISO 3834-3: Quality requirements for fusion welding of metallic materials — Part 3: Standard quality requirements
BS EN ISO 5817: Welding — Fusion-welded joints in steel, nickel, titanium and their alloys (beam welding excluded) — Quality levels for imperfections
BSEN ISO 14731: Welding coordination — Tasks and responsibilities
MEG are audited, accredited and certificated by the Building Engineering Services Competence Accreditation body (BESCA) to train, test and certificate staff required to weld pipework within the building and heating and ventilation industries & Heating & Ventilating contractors Association (HVAC).
Scope of services includes Manual Metal Arc welding (MMA), Tungsten Inert Gas and Oxy acetylene welding on various pipe diameters and wall thicknesses.
All MEG certification is third party accredited through Zurich Insurance PLC and is accepted throughout the construction and pressure regulated industries
Welder testing to the following standards:
BS EN ISO 15614 (compliant with CE certification requirements for structural steel companies working in accordance with BS EN 1090-2)
BSEN ISO 9606 (compliant with CE certification requirements for structural steel companies working in accordance with BS EN 1090-2)
Plate, pipe, ferrous and non ferrous
Weld Procedure testing can be expensive but once approved has unlimited validity; so it pays to have the most robust type of certification which will be accepted throughout the welding and pressure industries, always choose third party accredited certification. Testing can be undertaken either on site or at the welder test centre in Derby.
It is important when working to procedures that the equipment being used is accurate when selecting amperage and voltage values. We recommend calibration check certification to manage the sometimes unreliable/inaccurate welding machine outputs when older welding plant is being used.
