weld heat input

基本解釋

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.
隨著焊接熱輸入量的增加，由于熔池攪拌、焊接應力、合金元素燒損等原因，馬氏體的分布更加散亂和密集；

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.
在用有限元進行焊接溫度場的數(shù)值計算中，通過控制單元的生死，來模擬焊縫的形成和焊接熱量的輸入，計算結(jié)果與焊接溫度測試結(jié)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.
硬度測試結(jié)果表明，大線能量焊接熱處理后焊接接頭的硬度高于小線能量焊接的焊接接頭硬度。
