The procedure using anneal instead of normalizing will improve the productive efficiency of electroslagwelding joint.
用退火代替正火后的电渣焊工艺可大大提高生产效率。
2
The re-bar end used for electroslagwelding should be straight, flat and clean free of U-shaped, bruising, concave and convex, bending or distorted deformations.
电渣压力焊焊接使用的钢筋端头应平直、干净，不得有马蹄形、压扁、凸凹不平、弯曲扭曲等严重变形。
