Submerged arc welding wire SQ EM-12

Submerged arc welding wire
1carbon steel and low-alloy steel.
2Stable electric arc,low splashing,high depsition
3size:2.4-5.0

S
ubmerged-buried 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.
