Wide matching scope of welding parameters, soft arc, high frequency drop transition, high productivity. 焊接参数匹配宽,电弧柔和,熔滴过渡频率高,生产效率高。
Self-lubricating two-phase Ni-graphite alloy was produced by methods of vacuum medium-frequency induction melting, arc melting and containerless rapid solidification process of 3m drop tube assisted by high-frequency induction melting. 采用真空中频感应熔炼、电弧熔炼和高频感应熔炼辅助3m落管无容器快速凝固方法,制备出镍石墨两相自润滑合金。
Graphite smelting and solidifying in arc furnace is in globular shape, and homogeneous globular graphite is achieved in rapidly-solidified alloy prepared by 3m drop tube. 在电弧炉中熔炼并凝固,石墨基本呈球状组织形态,在3m落管中经深过冷快速凝固后石墨呈球状组织。
The arc phenomenon in energy storage argon point welding, the process of transition of melting drop, the selection of main elements of welder as well as effect of technology specification parameters on the quality of spot welding are also analysed in detail in the article. 文中对储能氩弧点焊的电弧现象、熔滴过渡过程、焊机主要元件的选定、电路设计以及工艺规范参数对焊点质量的影响作了详细的分析。
With a chutes arc quenching chamber, current limiting circuit breaker can lift the arc voltage to a high value through polar voltage drop and limit the short circuit current while interrupting circuit. 它采用多个栅片的灭弧室,利用近极压降将进入到灭弧室中的电弧电压提升到一个较高的值,从而在开断电路的同时还起到对短路电流的限制。
State spectrum of electric charge is obtained with the TOF method. At the same time, the arc current and arc voltage drop can also be measured. 电荷态谱是用TOF方法获得的,同时也测量了弧流及弧压降。
