How to choose welding materials for submerged arc welding?

Jan. 13, 2017

Sub arc wire and flux and welding wire are welding materials when submerged arc welding. Do you know how to choose them?


sub arc wire and flux


1. Low-carbon steel welding can choose high-manganese high-silicon type flux (HJ431) with XW-3(H08MnA) made in XinYu. And can also choose low manganese, manganese-free flux (such as HJ130, HJ230, etc.), with Xinyu XW-3, Xinyu XW-1 (H10Mn2) wire.

2. Low-alloy high-strength steel welding can be used in the manganese in silicon (such as HJ350) or low manganese in silicon (such as HJ250) type flux with appropriate low alloy high strength steel wire (such as: XW-8M (H08MnMoA) and XW-8M2 (H08Mn2MoA), etc.).

3. Heat-resistant steel, low manganese steel, corrosion-resistant steel welding can choose silicon or low silicon type flux with the corresponding alloy steel wire.

4. Ferritic, austenitic and other high alloy steel, the general choice of higher alkalinity melting flux or sintering, bonding flux, to reduce the alloying elements burning and infiltration alloy. Low-carbon steel and low-alloy high-strength steel welding should be selected and the strength of steel to match the wire; heat-resistant steel and stainless steel welding should be selected and similar to the composition of steel wire.

We provide high quality welding flux for you, welcome to consult us.
