Abstract

1314018 Welding by fusion MUREX WELDING PROCESSES Ltd 13 July 1970 [11 July 1969] 35093/69 Heading B3R A self-shielding coated electrode for manual electric arc welding comprises a core wire substantially of iron and containing as deoxidants 0À8-1À8% by weight Mn, up to 0À5% Si, and up to 0À25% Ti, present as alloying elements, and a coating forming from 20-60% by weight of the complete electrode, the coating including a substantial amount of rutile and deoxidants comprising not more than 5% by weight of the coating. The latter deoxidants may be less than 5% of ferro-manganese and silico-manganese, or a combination of these and other deoxidants (e.g. ferro-silicon or ferro-titanium), to a total of not more than 5% of the coating. Example 1.-Coating: 50% by weight rutile, 8% MgCO 3 6% CaCO 3 , 10% china clay, 10% mica, 2% silico-manganese (30% Si), 1% ferromanganese (80% Mn), 8% ilmenite, 4% felspar, 1% sodium alginate. Binder is sodium and/or potassium silicate. Core wire contains: C-0À06%; Mu-1À0%; Si-0À1%; S-0À03%; P-0À03%; bal. iron. Example 2.-Coating: 25% rutile, 1% ferromanganese (80% Mn), 1% ferro-silicon (50% Si), 53% iron powder, 8% china clay, 2% sodium alginate, 10% felspar. Binder is sodium and/or potassium silicate. Core wire contains: C-0À09%; Mu-1À5%; Si-0À2%; Ti-0À1%; S-0À03%; P-0À03%; bal. iron.
