weld heat input

基本解释

By increasing the weld heat input, the distribution of martensite becomes more dispersive and glomerate due to the molten pool stiring, the welding stress and the burning loss of alloy elements.
随着焊接热输入量的增加，由于熔池搅拌、焊接应力、合金元素烧损等原因，马氏体的分布更加散乱和密集；

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。
The hardness test show that the weld hardness with high welding heat input is higher than that with low welding heat input.
硬度测试结果表明，大线能量焊接热处理后焊接接头的硬度高于小线能量焊接的焊接接头硬度。
