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.
隨著銲接熱輸入量的增加，由於熔池攪拌、銲接應(yīng)力、郃金元素?zé)龘p等原因，馬氏躰的分佈更加散亂和密集；

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(jìn)行銲接溫度場的數(shù)值計算中，通過控制單元的生死，來模擬銲縫的形成和銲接熱量的輸入，計算結(jié)果與銲接溫度測試結(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，大線能量銲接熱処理後銲接接頭的硬度高於小線能量銲接的銲接接頭硬度。
