大口徑工業純鈦管道封底雙弧焊焊接方法,屬于管道焊接技術領域,適用于各行業大口徑(Φ≥600mm)鈦材管道、設備及其它有色金屬的根部焊接。將焊絲和焊件表面的油污和氧化物清理干凈;將管道進行坡口加工;進行管道組對,組對間隙為1~2mm;鈦管道內外兩支焊槍共同作業對鈦管道進行焊接,采用帶保護拖罩的鎢極氬弧焊槍,焊接時按焊接方向,焊槍噴嘴在前保護拖罩在后,外焊槍噴嘴氬氣流量25L~30L/min,內焊槍噴嘴氬氣流量15L~20L/min,外焊槍拖罩氬氣流量25L~35L/min,內焊槍拖罩氬氣流量25L~30L/min,外焊槍電流140~160A;具有容易控制焊縫成型質量,焊接速度快,是單弧焊焊接速度的3~5倍。節約能源和原材料等優點。
Welding method of double arc welding of large diameter titanium pipe
Large diameter of industrial pure titanium pipe back double arc welding welding method, belonging to the pipe welding technology, suitable for various industries of large diameter (600 mm) Φ acuity titanium pipe, equipment and other non-ferrous metal root welding.Clean the oil and oxide on the surface of the welding wire and welding parts;Groove processing of pipes;In the pipeline group, the interval is 1 ~ 2mm;Titanium pipe inside and outside the two torch assignments to welding of titanium pipes, together with belt protection cover of the tungsten electrode argon arc welding gun, welding in the welding direction and welding gun nozzle in former protection cover, the torch nozzle argon flow 25 ~ 30 l l/min, welding torch nozzle argon flow within 15 ~ 20 l l/min, the welding torch the argon gas flow drag cover 25 ~ 35 l l/min, the welding torch the argon gas flow drag cover 25 ~ 30 l l/min, the torch outside the current 140 ~ 160 a.It is easy to control the weld molding quality and fast welding speed, which is 3 ~ 5 times of welding speed of single arc welding.Saving energy and raw materials.
