起割點的操作一般情況下，水下切開進程多從被切開工件的邊沿初步，向基地切開，<a href='http://www.popechart.com/' target='_blank' class='key_tag'><font color=#2086ee><strong>水下封堵</strong></font></a>直至堵截;但有時受結構特征或環境所限，需從基地初步切開。從工件邊沿初步切開時，首先將割條端部觸及工件邊沿，并筆直于切開面，使割條內孔騎到工件邊沿棱線上，然后送電起弧。Z好選用接觸法引弧，初步時Z好不要移動割條，待工件平割操作技術潛水員下潛至切開工作點后，處于仰望割線的方位，一手持割炬，一手扶按在割線方向的方位。這么有助于切開方位的安穩，使割縫堅持平直。如在渾水中或能見度很差的水域中切開時，這么就可憑仗于割線上的導向定點(也可用導向繩導向)來指示切開方向。切開初步前，應整理好水面供氣管、信號繩、切開電纜等設備，使之處于手持割炬的一側，避免被電弧及飛濺起的熔渣燒壞。切開初步后，跟著電弧的點燃及割縫的延伸，潛水員應堅持住平衡的姿勢，一同沿著割縫的方向移動身體的上部，當抵達Z大極限后，再移動悉數身體的方位，繼續進行切開。切開進程中Z好能堅持切開的連續性，假設有必要間斷切開，則在切開下一段時，應從上段割縫的結尾處初步切開。為使割縫規整，可憑仗導尺(即靠模)進行切開。邊沿構成凹形口后再漸漸向基地移動，初步正常切開;也可在邊沿鄰近(離邊沿線的距離不逾越10mm)引弧，引弧后靈敏向邊沿移動，使邊沿口構成凹口，然后再向基地逐漸切開。從基地初步切開時，要比從邊沿初步切開簡單一些。首先將割條端部觸及工件，使之與工件的切開面成80°～85°角，然后選用接觸法或劃擦法引弧。引弧后堅持原地不動，直至割穿后再初步正常切開。</span></p><p

333px;"/></p><p style="line-height: 1.75em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">2) 正常切開的底子操作正常切開是指初步堵截構成后的切開進程，底子操作</span></p><p><br/></p><p style="line-height: 1.75em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">方法有以下3種：支撐切開法、維弧切開法、加深切開法。</span></p><p><br/></p><p style="line-height: 1.75em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">　　支撐切開法是指在引弧構成初步堵截后，割條傾斜并與切開面堅持80°～85°角，運用割條藥皮套筒支撐在工件表面上，割條移動進程中，一向不脫離工件的電弧-</span></p><p><br/></p><p style="line-height: 1.75em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">　　氧切開方法，該方法既可自左向右，也可自右向左，還可靠在規尺上切開，操作便當，功率較高，適用于中、薄板的水下切開。</span></p><p><br/></p><p style="line-height: 1.75em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">　　維弧切開法是指初步堵截構成后將割條提起，脫離工件表面約2～3mm，并與工件堅持筆直，然后沿切開線均勻地向前移動，一向堅持電弧不停息。該方法適用于厚度在5mm以下薄鋼板的水下切開。因為潛水員在水下堅持身體的安穩性較困難，故電弧不易堅持安穩。其他，切開質量也略低于支撐切開法，因此實習運用中不大選用維弧切開法。</span></p><p><br/></p><p style="line-height: 1.75em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">　　加深切開法是指在初步堵截構成后的切開進程中，割條不斷伸入割縫中，使割縫不斷加深，直到割穿工件，如此往復進行，終究將工件割開。該方法適用于選用支撐切開法一次不易割透的厚板或層板。操作時割條上下移動要調和均勻，以堅持電弧安穩燃燒。</span></p><p><br/></p></div> <h3
