Experience, individually and in partnership

Only the right combination of high-quality fluxes and matching wire or strip can create a perfect joint in submerged-arc welding. Since 1985, Bavaria Schweisstechnik has been developing and producing coordinated systems with flux and welding wire/strips for a wide range of applications.
