2、不管法兰焊接用的是哪种焊接方法,都需要做好焊前准备:

(1)FALANHANJIESUOXUSHEBEIJIGONGJU——YITAOSHOUGONGDIANHANSHEBEI,YITAISHOUBINGSHIJIAOMOJI,YIBADIANDONGQICHUI,YIBAPINGMIANCHI。

(2)法兰焊接前的检查工作——检查调试设备,确保设备正常运转;准备φ4.0J506焊条,最好在300℃-350℃烘干一小时,这是因为,焊条在储存、运输期间药皮会吸潮,使药皮中的水分增加,焊条烘干可降低药皮中的含水量,进而减少焊接过程中的飞溅,使焊接电弧能够稳定的燃烧;防止在焊缝中产生气孔;防止产生在焊接某些低合金钢时由氢引起的延迟裂纹。选择合适的焊接电缆、焊接铜轮、滚焊轮等焊接配件
