8、焊接与程序 Welding Preparation & Procedure

8.1、检查与修补 Checking and Repairing

⑴焊缝间隙最大为10mm。

Gap of root face is max. 10mm.

⑵清除坡口处油污、锈、灰尘等。

Remove the oil、dust、rust etc in groove.

⑶根据高强度钢焊接性要求,须对焊接区域进行预热至50-100℃,预热范围为焊缝两侧各50-100mm。

According to the requirement of high tensile steel weld ability , welding area must be carried out to fore-warm to 50-100℃ , and the range of fore-warm is 50-100mm on each side of welding seam.

⑷根据焊缝宽度选择合适的陶瓷衬垫,然后均匀地粘贴于焊缝背面.

In accordance with the breadth of welding seam , choose fit ceramic backing and then averagely stick it on the back of welding seam.

8.2、焊接程序Welding procedure

⑴每道焊层须检验气孔、药渣等缺陷，待清除后方可进入下道焊接。
