6012 Welding Rods

by Welding Electrodes on September 18, 2011

E6012 [E4312] electrodes are indicated by low penetrating arc and dense slag, which completely covers the bead. This might lead to incomplete root transmission in fillet welded joints. The covers are full of titania, usually exceeding 35 % by weight, in most cases are known to because the “titania” or “rutile” type. The covers generally also contain small quantities of cellulose and ferromanganese, as well as other siliceous materials for example feldspar and clay with sodium silicate like a binder. Also, small quantities of certain calcium compounds might be accustomed to produce acceptable arc qualities on dcen (electrode negative).

Fillet welds generally have a convex weld face with smooth even ripples within the horizontal welding position, and broadly spread harder ripples within the vertical welding position which become softer and much more uniform as how big the weld is elevated. Ordinarily, a bigger size fillet should be produced in the vertical and overhead welding positions using E6012 [E4312] electrodes in comparison to welds with E6010 [E4310] and E6011 [E4311] electrodes of the identical diameter.

The E6012 [E4312] electrodes are-position electrodes in most cases are appropriate for welding within the vertical welding position with either the upward or downward progression. However, more frequently the bigger dimensions are utilized within the flat and horizontal welding positions instead of within the vertical and overhead welding positions. The bigger dimensions are frequently employed for single pass, high-speed, high current fillet welds within the horizontal welding position. Their easy handling, good fillet weld face, and capability to bridge wide root openings under conditions of poor fit, and also to withstand high amperages make sure they are perfectly suitable for this kind of work. The electrode size employed for vertical and overhead position welding is generally one size more compact than could be combined with an E6010 [E4310] or E6011 [E4311] electrode.

Weld metal from all of these electrodes is usually reduced ductility and might be greater in yield strength (1 ksi to two ksi [.7 MPa to at least one.4 MPa]) than weld metal in the same size either the E6010 [E4310] or E6011 [E4311] electrodes.
