通过试验研究了预制不同程度的横向角变形和纵向弯曲变形的焊接接头经过机械矫正后的力学性能。结果表明,预制角变形12°、弯曲变形挠度30 mm的焊接试件经过机械矫正后,焊接接头抗拉强度、冲击韧性、硬度值等力学性能仍在标准允许范围内,焊接接头的冷弯性能满足标准要求。
The mechanical properties of the welded joints preformed with different degrees of transverse deformation and longitudinal bending deformation after mechanical correction were studied. The results show that mechanical properties of welded joints such as tensile strength, impact toughness and hardness are still within the allowable range after the mechanical deformation of welded specimens with preformed angle of 12 ° and bending deflection of 30 mm. The cold bending properties of welded joints Meet the standard requirements.
