The closed angle produced in the welding process of two round pipelines with the same diameter can result in velocity discontinuity, which makes it sharp for such a welding process to be realized, and so the arc transition correct method is given.
当焊接两圆管的直径相同时，施焊过程中会产生尖角，导致速度不连续，而难以在焊接过程中实现，由此确定采用圆弧过渡的修正方法。
Finally, these discontinuity conditions expressed in terms of generalized stress and generalized velocity on Timoshenko beam are used as an illustration.
