针对薄板构件焊接过程中压曲变形发生的力学机理，提出有源强化传热效应控制焊接压曲变形。应用数值方法研究了有源强化传热条件下的焊接温度场演变、分布及主要影响因素，为科学利用有源强化焊接传热效应提供了依据。研究表明，有源强化传热导致焊接温度场发生畸变，进而改变焊缝区压缩塑性应变量的大小与分布，从而达到有效地控制焊接应力与变形的目的。
Aiming at the mechanical mechanism of buckling deformation during the welding process of sheet metal parts, the active heat transfer enhancement effect is proposed to control the buckling deformation. The evolution, distribution and main influencing factors of the welding temperature field under the condition of active strengthening heat transfer are studied numerically, which provides the basis for scientifically utilizing the heat transfer effect of active strengthening welding. The results show that the active heat transfer leads to distortion of the welding temperature field, which in turn changes the size and distribution of the compressive plastic strain in the weld zone so as to achieve the purpose of effectively controlling the welding stress and deformation.
