Xiang Welding Industrial Co Ltd
High basic, agglomerated and neutral flux (without alloy–compensation) designed for overlay welding and joint cladding together with stainless strip electrodes of the Cr–, CrNi(Mo)–steel types. Applicable for ES–process as well as, especially, for use with the ESO® (Extended Stick Out)–cladding system which enables highest possible deposit rates as a result of the Joule heat (I2R–effect).EN 760: SA FB 2 DC gives excellent slag removal without slag residuals, especially in combination with Nb–alloyed strips, in the 1st layer on preheated substrates as well as in subsequent layers. The flux has low hydrogen potential, which makes it most suitable for overlay welding of heat resistant steels such as A387–types. Smooth weld bead appearance and notch–free transitions are features achievable with all cladding processes. Low but constant dilution rates can be gained when using process–characteristic welding parameters.EN 760: SA FB 2 DC shows constant chemical reactions as typical for a non–alloyed flux.

Application
EN 760: SA FB 2 DC can be used for joint cladding and surfacing of chemical plant components and equipments in the nuclear/offshore fields to yield corrosion resistant deposits in 1 or more layers. In combination with appropriate strip electrodes of the EQ300/EQ400 series according to A5.9 or according to EN ISO 14343 (EN 12072) constant weld overlays with low dilution rates are achievable.
