310s不銹鋼板焊接焊縫快速冷卻方法


310s不銹鋼板不僅將焊接試板浸在水中,而且每道焊縫焊接完成后,直接向焊道表面澆水來冷卻焊縫。試驗顯示,310s不銹鋼板采用焊縫澆水的冷卻方式,焊縫冷卻速度明顯加快,每道焊縫焊接完成后,只需澆水冷卻3min左右,焊縫溫度即降至40℃左右(手摸不燙)。澆水冷卻焊接如圖2所示。

310s不銹鋼板行了焊接工藝評定,工藝評定使用的310s不銹鋼板,焊接參數等與焊接試驗時相同。焊接試板打底焊完成后,將試板浸在水中,每道焊縫焊接完成后,310s不銹鋼板直接向焊道表面澆水來冷卻焊縫,待焊縫溫度降至40℃左右,使用電吹風將焊縫及兩側50mm范圍的水汽吹干,打磨清理干凈后,再焊接下一焊道。
