arc burn meaning in English
焊缝烧穿
Examples
- Welder s arc burns
电弧焊烧伤 - Due to two work states - - - arc burning and short current - - - existed in welding process of consumable electrode welding , and different control objectives in these two states , two close - loop feedbacks are designed in the control system : welding voltage feedback and welding current change rate feedback
根据熔化极co2焊机具有燃弧和短路两种工作状态，且两种状态下控制目标不同的特点，在控制系统中设计了双闭环反馈：焊接电压反馈及焊接电流变化率di / dt反馈。 - Abstract : the image of arc zone of flux - cored underwater wet welding was developed with underwater ccd camera system and composed filter technology . the discussion is mainly focused on the theory of edge detection . an image edge detection method based on median filter and grads algorithm was developed to detect the arc burning zone and arc bubble zone efficiently , which laid the foundation for further analysis of underwater wet welding arc mechanism and process control
文摘:通过复合滤光技术和水下ccd摄像系统，采集出了药芯焊丝水下湿法焊接电弧区域图像，重点论述了边缘检测理论，确定了基于中值滤波和梯度算子的电弧区域图像边缘检测方法，有效地区分了电弧燃烧区域和电弧气泡区域，从而为水下湿法焊接电弧的机理分析及水下焊接过程控制奠定了基础。 - Using the traits of arc adjust itself of the co _ 2 welding , adopting slow - descending feature or even feature of electrical source equipping with system that delivering the welding rod at the invariable speed , then , the arc burning steadily is realized , and the quality of welding is improved
利用co _ 2气体保护焊电弧的自身调节特性,采用缓降或平硬特性的电源配等速送丝系统,通过改变电源空载电压来调节电弧电压,再利用电弧电压和熔化速度之间的关系调节焊丝熔化速度使之等于送丝速度,最终实现电弧的稳定燃烧。
