Submerged arc welding fluxes

SIAT, boasting more than 40 years of expertise in the field, specializes in the production of submerged arc welding fluxes under the PITTARC trademark.

Submerged arc welding is an arc welding process: the arc fires beneath a bed of granular material called flux. When molten, due to the very high temperature, this flux partially turns into slag and acts as a shield for the heat so as to cope with the lack of thermal conductivity. This allows the heat to be confined in the weld pool and protects the molten weld from atmospheric contamination.

SAW welding can be performed using a number of techniques: single-pass, multi-pass, single-wire, tandem, twin-arc or multi-wire. Basic and semi-basic low hydrogen PITTARC’s fluxes allow to obtain joints with high mechanical characteristics, which can be used in a variety of fields, such as oil and gas, pressure vessels, wind towers, offshore applications and structural steelwork.
