چکیده

In this preparation for construction and assembly, as well as the design of the water tank connection of the fire extinguisher made of ۳۱۶L stainless steel, its use in hot areas with an environment that has an environment that can be highly evaluated, and then the agenda This tank for connection. The sheets in several versions and after field study, the best welding method to reduce distortion and residual stresses in the stored tank of the welding sequence and generate low inlet heat, which causes the least residual stress in the part. The desired quality of the resulting weld, according to the type of stainless steel and without complexity, should be welded by special instructions. Distortion and cracking is an important issue in thin section welding that requires control of the basemetals of the weld material. Quantum analysis was used to accurately determine the chemical composition of the sheet. The welding recipe uses a special electrode E۳۱۶L with a diameter of ۲.۵ mm, which was due to the exact dilution and temperature between passes, otherwise there was a possibility of freezing cracks in the welded parts. Reduction of residual stress levels from associated welding was considered. In the last penetrant test was performed to ensure the quality of the welds. Non-destructive testing was approved at all stages to evaluate the quality and health of the weld.
