➢ Welding process
                                         Any conventional fusion welding method can be used, such as submerged arc
                                         welding (SAW), manual metal arc welding (SMAW), flux core wire arc welding
                                         (FCAW), HIG, MAG (GMAW) and TIG (GTAW)
                                         Interpass temperature should be limited to a maximum of 200°C (392°F).


                                      ➢ Preheating

                                      TS 800  can  be  welded  without  any  crack  risk  according  to  following
                                      recommended conditions (forecast for highly clamped weld).
