pressure container welder 压力容器焊工
With adjustable eccentric pressure work piece applied on this welder, welding process is artificially controlled with proper current and upset force.
该系列对焊机采用可调的偏芯轮压紧工件的方式，选择合适的电流档位和顶锻力，人控焊接时间完成焊接过程。
Consequently it is difficult to optimize the welding pressure in pressure constant mode used in conventional ultrasonic plastic welder.
传统焊机的压力不变模式使得焊接工艺很难优化。
As stipulated by"the testing regulation of container of pressure of boiler to welder", the prototype of arc welding to the joined slit must be completed through the crafts of groove by bevelling.
前言： 根据“锅炉压力容器焊工考试规则”规定， 对接缝手工电弧焊的考试试板必须采用单面焊双面成形工艺完成。
