Calculation, design and fabrication of welding heat treatment equipment.

Welded joints, especially those between different types of materials, always have many problems that need to be handled to improve the quality of the welds and the life of the equipment. Welds before heat treatment appear weld stress, crystalline segregation and heterogeneous weld organization. This affects the quality of parts when working, especially those working in long-term conditions, under heavy loads, or constantly changing loads. To ensure the quality of the weld, it is necessary to heat and treat the weld immediately after the welding is completed. Weld heat treatment equipment is the solution that plays an important role in the heat treatment of welds. This study has calculated, designed and manufactured a welding heat treatment device, and at the same time, conducted testing on the device. The test results show that the homogenized microorganism no longer has the phenomenon of segregation or carbide accumulation. In the weld immediately after welding, the hardness is significantly reduced, and the impact toughness is increased. Weld heat treatment equipment is designed to meet the needs of improving weld quality. This study's weld heat treatment equipment responds well to improving weld quality. [ABSTRACT FROM AUTHOR]
