摘　　要：通过对国产09MnNiDR及采用ASME规范的SA203-D等低温材料的焊接试验及生产应用,阐述了控制焊接线能量对低温钢焊接的重要性。After the test and manufacture of the low - temperature material, such as domestic material 09MnNiDR and ASME Code material SA203 D, we acknowledge the character of the low - temperature steel and we also find the reliable problems occurred during welding. This text emphasized the important point during welding.

关 键 词：低温钢 焊接材料 焊接工艺评定试验 焊接制造
