ratio-frequency welding

The interaction between laser beam and plasma arc, which changed with laser power and welding speed, had an important influence on weld width and ratio of bottom to top width of weld.

激光/等离子电弧协同效应随激光功率和焊接速度变化而不同，从而影响复合焊焊缝的熔宽和熔宽比。

Using transient current and voltage waveforms collected by welding quality analyzer Hannover in gas metal arc welding ( GMAW) process, the power ratio indices was defined from date math statistical methods.

利用焊接质量分析仪采集气体保护焊焊接过程中瞬时电流和电压波形特征，对测的数据进行数学统计，提出电源功率比率指数的概念。

The results show that welding with backing has lower dilution ratio of matrix than without backing.

实验结果显示,在稀释率方面,有水冷却对母材的稀释率较无水冷却时低.

However, the voltage welding has lower temperature peak value , wider welded seam, and smaller depth-to-width ratio.

而中压下电子束焊接时的温度峰值较低, 且焊缝较宽,焊缝深宽比较小.

This paper expatiates on the sampling test method of NDT on welds, discussing the sampling positions and ratio through welding procedures and welding condition analysis, which is of referential value to testers and QC personnel.

为此，对焊缝无损探伤抽查法作了较为详细的说明和分析，特别是从焊接工艺、施焊条件分析方面对抽查部位、抽查比例进行探讨，对检查人员和质量管理人员来说都具有参考价值。

When welding current increased from 0 to 60 A, the weld width increased slightly and the ratio of bottom to top width of weld kept constant.

随焊接电流从零增大到60A，焊缝熔宽略有增大，而焊缝熔宽比基本保持不变。
