Based in malaysia beginning in 1997 , he planned and implemented wds consolidation of all worldwide hard drive manufacturing into malaysia in january 2000 , the expansion of the companys drive operations into thailand in january 2002 and manufacturing operations related to the acquisition and integration of the read - rite magnetic head business in thailand in august 2003 自1997年初以来，他就计划以马来西亚为基地合并wd全球所有的硬盘制造业务， 2000年1月wd的硬盘制造业务全部转移到马来西亚， 2002年1月该公司的硬盘部门向泰国扩张，并于2003年8月在泰国建立了与read - rite磁头业务的采购和整合相关的制造部门。
There is ultra - clean workshop of 1200 square meters . production techniques and equipments from japan have been applied in the production of magnetic heads for vhs video tape recorders . in 1999 the company started to produce magnetic heads for high - resolution digital camcorders . all these products have been supplied to manufacturers of products of world - famous brands in korea and japan . the company is iso9002 certified 创立于1994年，深圳粤宝电子工业总公司绝对控股经营的中外合资公司，拥有1200平方米的洁净生产车间，采用日本工艺技术和设备，专业生产vhs录像机磁头， 1999年开始生产高画质的数码摄录机磁头，供应日本和韩国的著名厂家， iso9002质量体系认证企业。
Based on characteristics above , a new theory of “ controlling movement by moving ” is proposed , which means that controlling welding arc by moving magnetic field . a new device for generating rotating magnetic field is designed ; magnetic head and excitation power source are included 本文基于以上几种磁场形态和励磁方式的特点,提出了“以动制动”的控制思想,即用动态变化的磁场来控制电弧的运动,研制了一套新型旋转磁场发生装置,本装置包括磁头装置和励磁电源两部分。
Magnetic head is designed by six magnetic poles in symmetrical distribution , the design of excitation loop and excitation angle makes magnetic field act on welding arc region which could control welding arc effectively . the insulation , cooling and hermetization of magnetic head avoid the influence on magnetic field of outside ; miniaturization design of magnetic head could achieve different welding process 磁头装置采用六磁极对称励磁方式设计,励磁线圈和励磁角度的设计使产生的磁场恰好作用于焊接电弧区域以实现对电弧的有效控制;磁头的绝缘,冷却,密封设计避免了焊接过程中外界因素对磁场的干扰;磁头整体的小型化使该装置可以实现多种形式的焊接工艺。
