Features Specificati***: Submerged-Arc Welding Wire
Submerged-Arc Welding Wire
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.
