welding heat input

基本解釋

With large welding heat input, more upper Bainite and granular Bainite form, which is benefit to improve the property of HAZ.
采用大的線能量焊接，形成較多的上貝氏體和粒狀貝氏體組織，對(duì)改善接頭性能有利。
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，還研究了焊接熱輸入量對(duì)局部脆性區(qū)斷裂韌性的影響，并通過(guò)定性、定量的金相顯微組織評(píng)定對(duì)試驗(yàn)結(jié)果進(jìn)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.
在用有限元進(jìn)行焊接溫度場(chǎng)的數(shù)值計(jì)算中，通過(guò)控制單元的生死，來(lái)模擬焊縫的形成和焊接熱量的輸入，計(jì)算結(jié)果與焊接溫度測(cè)試結(jié)果很接近。
