简介：增加焊接穿入的A-TIG的机制被使用我们为不锈钢开发了的激活的流动学习。流动和焊接水池的温度领域上的流动的效果被PHOENICS软件模仿。它证明没有流动，液体流动将沿着焊接水池然后在下面的表面是外面的，导致flatter焊接水池形状。与流动，氧，从否定价值把表面紧张毕业生的温度依赖改变到积极价值，能在焊接穿入上引起重要变化。液体流动将沿着向中心然后在下面的焊接水池的表面是里面的。这个液体流动模式高效地把热转移到焊接根并且生产相对深、狭窄的焊接。这个变化是穿入增加的主要原因。而且，弧建设能引起焊接宽度变得更狭窄并且变得更深的穿入，但是这不是穿入增加的主要原因。焊接水池表面和弧侧面的液体流动上的流动的效果在焊接的常规TIG并且在由使用高速度的摄像机焊接的A-TIG被观察。液体流动行为被微集中的X光检查传播录像观察系统在实时规模设想。结果显示与更狭窄的宽度和更深的穿入导致焊接祷告的更强壮的里面的液体流动模式能显然在焊接的A-TIG的情况中被识别。流动能在焊接水池改变液体流动的方向。它与模拟结果有一个好协议。
