About EST-Einseitenschweißtechnik
EST-Einseitenschweißtechnik Handels GmbH is a Hamburg family business founded in 1974 that supports shipyards, steel construction, pipe fabrication and repair operations primarily with ceramic weld backing bars. In addition to flat and round ceramics in various groove shapes and dimensions, with and without aluminum adhesive foil, the company frequently develops innovative and in some cases patented solutions in close cooperation with its customers, simplifying welding challenges. The portfolio covers special applications, including welding of aluminum, arcs of custom radii, curved surfaces, Holland profiles, HV and X seams, UP cross joints, and butt joints without run-off tabs. For hard-to-access applications in repair operations, solutions with fiberglass tape are offered. The company provides consulting on weld backing bars and distributes its products from its location at Eichenweg 31 in Hamburg. The legal form is a GmbH (HRB 51226, Hamburg Local Court).
