Product Detail

SPECIFICATION

Product Tags

Suitable for civil construction, steel frame, steel pipe hook, chimney, pipe and other structural parts of outdoor welding.
The standard we met: GB/T10045 T 49 Z T7-1 N A , AWS A5.20 E71T-A & A5.20M E491T-7, ISO17632-A:T42 Z Y NO 1, ISO 17632-B:T49 Z T7-1 NO A, JIS Z3313 T49ZT7-1NA.

What are the
characieristics?

●The melting drop is fine melting drop transition or spray transition.

●With good penetration depth, good wetting degree and fast melting filling speed.

●Low sulfur content of weld metal, good crack resistance.

●Small diameter welding wire can be used for full position welding.
