The groove shapes, welding methods, filling materials, procedure parameters and concrete weldingsequence are provided.
给出了这些管段焊口的坡口形式、焊接方法、焊接材料、焊接工艺参数及实焊工艺程序。
2
The inspecting standards from installation, selection of materials, weldingsequence and groove shapes to the welding check are given a minute description.
从安装、组对、焊材选用、焊接顺序、坡口形式到焊接检验、验收标准均进行了详细叙述。
