The acquired data can reflect the factual welding process rightly, furthermore, the welding process can be well repeated by using the welding parameters.

采集的数据能正确反映焊接实际过程，焊接参数经还原后可实现焊接过程参数的可追溯性。

In addition to causing the welding line to break off, may also lead to other local damage near the welding line, such as sealing data.

除了招致焊接线烧断外，还可能招致靠近焊接线的其他局部损坏，例如密封资料。
