welding heat input

基本解释

With large welding heat input, more upper Bainite and granular Bainite form, which is benefit to improve the property of HAZ.
采用大的线能量焊接，形成较多的上贝氏体和粒状贝氏体组织，对改善接头性能有利。
In addition, the effect of welding heat input was studied. Qualitative and quantitative metallographic examination of the simulated microstructures was made to assist t…
此外，还研究了焊接热输入量对局部脆性区断裂韧性的影响，并通过定性、定量的金相显微组织评定对试验结果进行了分析。
Numerical computation of 3D welding temperature distribution was carried out by using element birth and death to simulate the forming of weld bead and welding heat input.
在用有限元进行焊接温度场的数值计算中，通过控制单元的生死，来模拟焊缝的形成和焊接热量的输入，计算结果与焊接温度测试结果很接近。
