Phoenixweld SW12MnSi is a submerged arc welding wire for mild steel and 490MPa high tensile steels. It is recommended for a wide range of applications including shipbuilding, steel structures, steel pipeliner, and heavy machinery.
It may be used with several Phoenixweld fluxes depending on the required specifications and application needs. Heat input should be maintained between 2.0 and 3.0 kj/mm for good weld properties.

Flux used with the wire should be dry and free of impurities. It should be rebaked according to manufacturer’s recommendations if there is any risk of moisture in the flux. Choose a flux that matches the application requirements for surface condition, material thickness, and desired mechanical properties.
Contact tips should be replaced regularly to avoid arc instability and poor wire direction due to tip wear.
