The welding shall be started at room temperature or afterapplying any preheating if required by the welding consumable standard. The interpass temperature shall be inaccord

26、ance with the welding consumable standard.The preheating and interpass temperatures shall be measured using temperature indicator crayons, surfacethermometers or thermocouples, see ISO 13916.The welding conditions used, such as current, voltage, travel speed, weld bead size, shall be within the rang

27、erecommended by the manufacturer and where the test is performed for classification purposes in accordance withthe limits specified in the relevant consumable standard.7 Heat treatmentAll heat treatments required for the butt weld, except hydrogen removal treatment shall be carried out on thecomplet
