Submerged Arc Welding is a process which requires a continuously fed, consumable, solid or tubular (metal cored) electrode. The molten weld is protected from atmospheric contamination by being submerged under a blanket of granular flux consisting typically of lime, silica, manganese oxide, calcium fluoride and other compounds.
Welding machine K355AM Suspension-type welder 355 of -4501U1 type is designed for contact flash welding by pulsating flashing of rails with cross-section ranging from 6400 to 10000 mm2 and for field flash trimming right after welding. The welder can be powered from AC mains, diesel-generator plant and motor-generator set.

S355J2G1W test temperature: When S355J2G1W steel is tested at -20 centigrade, the Notch impact test. Min. absorbed energy is 27J. It is same when it is tested at 0 centigrade. Bebon International can offer more information about S355J2G1W welding property and S355J2G1W test temperature,we also can supply other grades like: A 588 Gr.
Welding: The fine-grain structural steel grades of this series can be perfectly welded both manually and using automatic equipment by means of all known welding processes, not least due to their reduced carbon content and the low carbon equivalent value. The tables below show the mechanical properties of grade S355ML
Solid welding wire for S355 - St52-3 steels S355 is a standard type of carbon steel with a yield strength of 355 N/mm2, practically all welding consumables do offer a yield strength far above and this type has no welding restrictions or the material has to be really thick.
Processes Of Welding Influence of welding processes and parameters also are to be considered for welding of stainless steels. The major welding processes are: Shielded metal arc welding (SMAW) TIG welding MIG welding SMAW Welding In shielded metal arc welding, the consumable used for welding is a coated electrode. The
