Instructions for the user

The aforementioned information and technical data have been compiled as a support for the user in selecting the strip-powder combinations which are best suited for each specific submerged-arc-RES welding requirement. The exact, specific application as well as the approvals should be discussed with us before use.

The properties should be regarded as minimal data for the condition without removal; the values are based on laboratory and approval tests. In the case of multipass welding, the data are based on the pure, untreated test weld metal as specified in EN 756, with the application of the measuring set-up as specified in EN 1594-1 or AWS A 5.17 / 5.23, if mentioned. For single-pass welding (pass / capping pass), the measuring set-up specified in EN 1597-2 has been employed. The European regulations for strip electrodes and welding powder for submerged-arc welding are similar to the corresponding ASME / AWS standards A 5.17 / 5.23 for carbon and low-alloy steels or for corrosion-resistant stainless steels (AWS 5.9).

During the single-pass or two-pass welding process, both the dilution with the base metal and the heat input affect the mechanical properties of the weld. Consequently, the selection of the best-suited strip-powder combinations as well as appropriate process tests before use are decisive. The same applies to strip-powder combinations which have already been approved. Details can be furnished upon request.
