General Data for all 347 MMA Electrodes Storage

3 hermetically sealed ring-pull metal tins per carton, with unlimited shelf life. Direct use from tin is satisfactory for longer than a working shift of 8h. Excessive exposure of electrodes to humid conditions will cause some moisture pick-up and increase the risk of porosity. For electrodes that have been exposed: Redry 200 – 300°C/1-2h to restore to as-packed condition. Maximum 400° C, 3 cycles, 10h total. Storage of redried electrodes at 50 – 200°C in holding oven or heated quiver: no limit, but maximum 6 weeks recommended. Recommended ambient storage conditions for opened tins (using plastic lid): < 60% RH, > 18°C.

All-positional rutile MMA electrode for 321/347

MMA rutile flux coated 347 electrode on high purity 304L core wire. Ultramet 347 has all the benefits of an advanced rutile flux design, including all-positional fixed pipework welding with the 2.5/3.2mm diameter electrodes. Recovery is about 110% with respect to core wire, 65% with respect to whole electrode. E347-16 E 19 9 Nb R32 19.9.Nb.R E 19 9 Nb R 23

ULTRAMET B347 Product description

Basic pipe-welding electrode for 321/347

MMA electrode with basic carbonate-fluoride flux on high purity 304L core wire. Designed to give good moisture resistance and hence freedom from weld porosity. The electrode is particularly suited to positional welding of fixed pipework qualified in the ASME 5G/6G position and is tolerant to adverse wind and draughts under site conditions. Compared with rutile types, the basic flux gives a more convex fillet bead profile and although the slag does not self-lift, it is easily removed and gives welds of exceptional appearance and quality. Recovery is about 110% with respect to core wire, 65% with respect to whole electrode. E347-15 E 19 9 Nb B 42 19.9.Nb.B E 19 9 Nb B 20+
