| Description |
A heavy coated basic - iron powder type hydrogen controlled electrode with very good operating characteristics like smooth & steady arc, controlled molten slag- metal pool and easily slag detachability. The weld deposit is tough and highly crack resistant. Suitable for positional welding also. Weld deposit is of high radiographic soundness. |
| Application |
Joining and building up of low carbon, medium tensile and high tensile steels with sub zero temperature impact requirement upto - 40 deg. C. suitable for joining thick low carbon and medium tensile steel plates under stressed condition and buffer layer prior to hard - surfacing. Application includes storage tanks, pressure vessels, earth moving machinery, penstocks etc. |
