| Description |
A heavy coated basic - iron powder type hydrogen controlled electrode with very good operating characteristics in flat and other positions. The electrode produces a smooth arc with least spatter and highly controlled molten slag - metal weld pool. The slag detachability is very good and bead is smooth, even shaped and finely rippled. Weld deposit is of high radiographic soundness. |
| Application |
Joining of mild, medium tensile, micro alloyed and low alloy steel e.g. IS 2002 GR.1 & 2, IS 2062 Gr. C, IS 1875 Class 2, 2A, 3, ASTM A 633, Ship steel of A, D & E quality, Fe 440B, Fe 490B, SAIMA 410, TISTEN 52, TISTEN 55 and equivalent grades. |
