A novel soft-switching twin arc pulse MAG welding inverter

WANG Zhenmin, XUE Jiaxiang, WANG Fuguang, HUANG Shisheng

Frontiers of Mechanical Engineering 2007, Volume 2, Issue 2,   Pages 224-227 doi: 10.1007/s11465-007-0039-1

Abstract: The high-speed double wire pulse metal gas arc (MAG) welding process possesses advantages of automation and high efficiency and quality. Thus, it attracts much more attention nowadays. To meet the requirements of the double wire pulse MAG welding process, a novel double wire pulse MAG welding inverter integrated with technologies, such as soft-switching, double closed loop control, and synchronic control, is produced. A complete performance test was done for the pulsed MAG welding power supply by using a computer testing platform. The results of the experiment indicate that the novel welding inverter has an excellent performance both in the dynamic and the static characteristics. Also, the synchronic control between the master inverter and the slave inverter is reliable.

Field measurement and analysis of asymmetric shallow buried twin tunnels with ultra small spacing

Wang Yunlong,Tan Zhongsheng,Chen Ying

Strategic Study of CAE 2012, Volume 14, Issue 11,   Pages 24-28

Abstract:

The ultra-small spacing tunnel of Jiaozhou Bay seabed tunnel in Qingdao is took for example; the surrounding rock pressure features and support force are analyzed through the field measurement. Results show that the surrounding rock pressure and support force of the after-excavation tunnel are larger than others of the tunnel. This result is different from the theoretical predictions and experimental results of most of the small spacing symmetry tunnel. To alleviate these problems effectively, support parameters are adjusted opportunely; the radial support capacity of the after-excavation tunnel is enhanced, and reinforcement measures of rock pillar are made at the same time. The monitoring results show that the stability of the after-construction tunnel has been effectively controlled, which provides useful reference for the design and construction of similar tunnels with small spacing.
