About Karstens Watercut & Welding

Karstens Watercut & Welding is a specialist company in metal construction based in Kröppelshagen near Hamburg. The company specialises in waterjet cutting (stationary up to 4,000 × 2,000 mm as well as mobile), welding work (MIG/MAG, TIG, spot welding) and special metal construction with design engineering. A focus is mobile cutting, drilling and welding technologies for dismantling and repair, such as the material-preserving, spark-free production of flat surfaces and boreholes up to 600 mm in steel, the splitting of shafts or the creation of inspection and access openings. Steel and other metals are the main materials processed. References include the repair of the cable wheel bearings of the Rethe bascule bridge in the Port of Hamburg for the Hamburg Port Authority (2009). The company works for metal construction, port and maritime technology, bridge refurbishment, the ordnance clearance sector as well as private customers (including custom hunting seats and special fabrications via waterjet cutting). It is available with 24/7 standby service.
