COROMIG PROVIDED WELDING STRENGTH FOR BOAT LIFT

Process: MIG

In the construction of the Falkirk Wheel Boat Lift used to lift and transfer barges between the Clyde and Union Canals in place of a flight of nineteenth century locks, Butterley Engineering made extensive use of Coromig 58 metal cored welding wire from Murex Welding Products. It provided the quality and consistency of weld demanded by the company in fulfilling this prestigious contract through the construction of structural steelwork forming the gondola pods, rotor and axle.

Fabricator Butterley Engineering of Ripley in Derbyshire is a long standing convert to Coromig metal cored wire for fillet welding applications and previously used Coromig 57 before the latest generation 58. "We have yet to find an alternative cored wire that provides such economy, ease of use and reliability" says Richard Reeve, Butterley Engineering's Welding Engineer.

The moving structure of the Falkirk Wheel Boat Lift, is thirty five metres high, thirty five metres wide and thirty metres long and has a capacity of 600 tonnes. In its fabrication some 5.5 tonnes of Coromig 58 was utilised for fillet welding a range of carbon manganese steels to BSEN 10025, S355 and J2G3. In addition, two tonnes of Coromig B55 were used.

Butterley's welders are extremely familiar with using Coromig metal core wire and the latest generation Coromig 58 has a number of properties which promote its versatility in use. Suitable for general mild steel welding applications with materials in excess of 5mm thick, it can be used with both CO2 and Argon/CO2 shielding gases. It is particularly well suited for single run weld fillets in most positions when using CO2. It gives low slag levels and minimal spatter. It is provided on handy wire basket type spools weighing 16kg.
