Performance
Used for submerged arc weldings of carbon steel, alloy
steel (e.g. 16Mn, etc.). it features excellent metal
mechanics property, stable arc. convent to remove
welding slag, good figuration, can use auto and
semi-auto multi-times weld, double surfaces weld, single
wire and multi-wire weld at high speed, etc.

Use
Used in the boiler, shipbuilding, pressure
container extensively, such trades as the
steelframe etc. are suitable for the moderato,
the welding of the thick more board. |
