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。

Plan Of Welding Procedure Approval Test
Each of the weld layer is disposed and inspected defects such as pores , overlaps, etc should be disposed of before continuing next layer.
⑵焊接后的缺陷如气孔等采用碳刨清除,再进行焊接。

After welding , the defeats such as pores etc will be disposed by digging and welded later.
8.3二氧化碳焊丝须谨慎使用。

Cautious to use CO2 wire.
⑴雨天、雾天及湿度大的天气不能焊接，焊缝表面如有水分，干燥后再进行焊接。

Welding work is not carried out in the rainy day , foggy day and heavy humidity day ,The welding seam to be welded shall be dried ,if there is water on the surface of the welding seam area.
⑵如遇气候有风，应采用挡风板，以防产生气孔等缺陷。

Plates of warding off wind will be adopted to avoid ing into being the defeats such as pores etc if it is windy.
⑶焊接结束后须对焊接区域进行保温，以期缓冷，防止骤冷产生裂纹。

After pleting weld, welding area must be carried out the heat preservation which can be cold slowly and prevent sudden cold from ing into being the crack.
