welding heat process

基本解釋

The microstructure and properties of X80 steel will be changed greatly because of heat cycle in welding process.
X80管線鋼在焊接過(guò)程中，熱影響區(qū)由于受到焊接過(guò)程熱的作用，其組織和性能會(huì)發(fā)生較大的變化。
Appropriate welding material, election of soldering acid, design of welding heat process and cleaning up influenced the welding quality significantly.
合理的焊接材料、釬劑的選擇匹配，焊接加熱程序的設(shè)計(jì)，焊接部位的徹底清理將對(duì)端環(huán)的焊接質(zhì)量具有極大的影響。
Temperature field distribution of weldment , which reflects complex welding heat process, is a basic on studying welding deformation, residual stress and so on.
焊件中的溫度場(chǎng)分布反映了復(fù)雜的焊接熱過(guò)程，是研究焊接變形、焊后殘余應(yīng)力等狀況的基礎(chǔ)。
