SANDVIK WELDINGHANDBOOK
TABLEOFCONTENTS WELCOMETOSANDVIK We are a world-class developer and manufacturer of stainless steels and special alloys for demanding environments. And for more than 80 years one of the leading global suppliers of welding materials. D0 Welding is all about cleanliness and choosing the right filler metal. These guidelines are a step-by-step aid to welding stainless steels and nickel alloys. CHOOSINGWELDINGCONSUMABLES The tables are guides for choosing the correct welding consumable when welding similar or dissimilar materials. If the materials you need to join are not on the list please contact us. JOININGSIMILARMATERIALS 12 The table gives typical selections of welding consumables and basic designations for wire electrodes and filler wire/rods. It does not indicate the silicon-alloyed variants used for MIG welding or the variants of covered electrodes or wire-flux binations for submerged arc welding. JOININGDISSIMILARMATERIALS 13 The table gives our remendations for the most suitable welding consumable when dissimilar materials are to be joined. If the materials you need to join are not on the list please contact us.
SHIELDING THEWELD 16 The primary tasks of a shielding gas are to protect the weld pool from the influence of the atmosphere and to stabilize the electric arc. 18 Sandvik welding wire and rods are filler metals optimized for MIG (GMAW) TIG (GTAW). plasma-arc (PAW) and submerged-arc welding (SAw). These are available in stainless steels and nickel alloys. 154 Strip electrodes are used in electro-slag welding (ESW) and submerged arc welding (SAW). 196 Sandvik provides welding fluxes for joint welding and surfacing in submerged arc welding (SAW) and electro- slag welding (ESW). 224 Sandvik's flux cored wire electrodes are of rutile type and have an austenitic stainless steel sheath. 256 Shielded metal arc welding (SMAW) or manual metal arc welding (MMA) is a slow but versatile welding method and is therefore an important plement to other welding processes. 353 Thermal spraying wire in a wide range of alloys for high- temperature corrosion protection bonding layers and sealing.
FERRITECONTENTDIAGRAMS 380 Schaffler Delong and WRC-92 diagrams for predicting ferrite levels from the position of austenite and ferrite stabilizing elements and thereby reduce the risk for hot cracking during welding.
WELCOMETOSANDVIK At Sandvik it's innovation that makes the grade. We are a world-class developer and manufacturer of stainless steels and special alloys for demanding environments. And for more than 80 years we have been one of the leading global suppliers of welding materials in stainless steel and nickel alloys.
