Applications
For all-position welding of generalstructures.

It is good, and bead appearance is also beautiful, andweldability and workability are excellent also in themechanical performance.

All position

For all-position welding of generalstructures.

This welding rod is lime-titania type. It has welding
workability, an X ray performance, and a goodmechanical performance. It excels in the workability ina vertical and an overhead position, and a beautiful
bead is obtained easily. Pipe welding shows goodworkability.

All position

For welding of steel sheets and lightstructures.

This shows good usability in flat and horizontal fillet
welding particularly. The arc is stable with littlespatter, and the slag covering and its removability aregood. This is suitable for welding steel sheets, because
a lustrous and beautiful bead with shallow penetration
can be obstained.

removability are good. Uniformity of the beads andresistibility to undercuts are good.
This rod makes easier re-arcing, and the slag coveringand its removability are good. Reliable tack weld can beperformed. When a proper welding current is set, it
makes all-position welding possible including verticaldown welding. There is also an H type whichstrengthened re-arcing.
