Non-copper Coating MIG wire for high tensile steel 490MPa Grade
Approval:
CE, JIS
Application:
Suitable for the welding in shipbuilding, bridge, structure, excavating machinery, also suitable for welding high current thick plate butt welding, fillet welding, and horizontal welding.
Characteristics:
1. On top of the added Si and Mn, also added enough Ti to be able to stabilize the arc, and make a fine grained arc transition, and with much less spatter and smoke; 2. Ti can make the weld bead with finer grain, and increase the toughness of the weld bead, which can performed well under high current.
Polarity:
DC+
