水下电弧-氧切割的操作方法有几点?

    1) 起割点的操作 一般情况下,水下切开进程多从被切开工件的边沿初步,向基地切开,直至堵截;水下安装拆除但有时受结构特征或环境所限,需从基地初步切开。 从工件边沿初步切开时,首先将割条端部触及工件边沿,并笔直于切开面,使割条内孔骑到工件边沿棱线上,然后送电起弧。最好选用接触法引弧,初步时最好不要移动割条,待工件边沿构成凹形口后再渐渐向基地移动,初步正常切开;也可在边沿邻近(离边沿线的距离不逾越10mm)引弧,引弧后灵敏向边沿移动,使边沿口构成凹口,然后再向基地逐渐切开。 从基地初步切开时,要比从边沿初步切开简单一些。首先将割条端部触及工件,使之与工件的切开面成80°~85°角,然后选用接触法或划擦法引弧。引弧后坚持原地不动,直至割穿后再初步正常切开。
