Bohler FOX A 7-A description: Rutile basic electrode, for joint welding of dissimilar joints, problem steels and for repair and maintenance. Very popular electrode for numerous applications. The weld metal offers exceptionally high ductility and elongation together with outstanding crack resistance. There is no fear of embrittlement when operating down to service temperatures of –100C or above +500C. The scaling resistance goes up to +850C. When working at service temperatures above +650C please contact the supplier. The weld metal can be post weld heat treated without any problems. The deposit will work harden and offers good resistance against cavitation. Ductility is good even after high dilution when welding problem steels or when subjected to thermal shock or scaling. An excellent alloy providing cost effective performance. BOHLER FOX A 7-A is suitable for both AC and DC.
