双层壁波纹管的内部焊接工艺!

作者: admin    来源:http://www.laobingguandao.com  时间:2019-07-31    人气:
  采用GTA和LB焊接工艺,用于焊接双层钢带内波纹管的焊接夹具要求焊枪、激光束聚焦装置和接头与垂直平面倾斜约30°。因此,电弧或光束以较小的角度穿透焊接接头。这里的主要问题是要保证工件完全暴露在焊接夹具上面,达到最大要求
  GTA and LB welding processes are used to weld double-layer steel strip inner bellows. The welding fixture requires welding torch, laser beam focusing device and inclination of joint to vertical plane about 30 degrees. Therefore, the arc or beam penetrates the welded joint at a smaller angle. The main problem here is to ensure that the workpiece is completely exposed to the welding fixture to meet the maximum requirements.
  小渗透。在所有位置焊接时,接头必须至少比夹具高4.548毫米。然而,夹具高度过高也会使组成部件的不锈钢板之间难以保持接触。夹具必须调整几次。由于本研究中每个零件的尺寸偏差,无法完全解决这个问题。两种焊接工艺参数均无法调整
  Small penetration. Joints must be at least 4.548 mm higher than fixtures when welded at all locations. However, too high a clamp height also makes it difficult to maintain contact between the stainless steel plates of the components. The fixture must be adjusted several times. Because of the size deviation of each part in this study, this problem can not be completely solved. Neither of the two welding parameters can be adjusted.
  四舍五入,以充分补偿尺寸偏差。因此,两种焊接工艺在同一焊缝不同部位的焊接深度差别很小。表I中的数据是通过横向测量得到的,根据在}5的区间内沿正确方向切割的若干截面。
  Round off to fully compensate for size deviation. Therefore, there is little difference in depth between the two welding processes at different parts of the same weld. The data in Table I are obtained by transverse measurements based on cross sections cut in the correct direction within the} 5 interval.
  为了减小内焊缝的焊接变形,PA焊接系统采用脉冲焊接电流。PA焊接夹具和焊枪定位符合GTA maximus设备。但是,对PA焊接工艺的评估要晚得多,此时各部件的尺寸波动较小,对波纹管夹具进行了调整,使其达到最佳状态,焊缝深度较高

  In order to reduce the welding distortion of the internal weld, the pulsed welding current is used in PA welding system. PA welding fixture and torch positioning conform to GTA maximus equipment. However, the assessment of PA welding process is much later. At this time, the size fluctuation of each component is small. Corrugated pipe clamp is adjusted to achieve the best state and the depth of weld is higher.
  是稳定和一致的。
  It's stable and consistent.
  将充满压缩气体的空气管插入双层壁钢波纹管中,通过空气孔与波纹管连接。然后展开排气管的一端。喇叭口设置在充气眼上。一个弹簧加载的设备安装在浮管上,以启用
  The air pipe filled with compressed gas is inserted into the double-walled steel bellows and connected with the bellows through air holes. Then expand one end of the exhaust pipe. The bell mouth is arranged on the inflatable eye. A spring-loaded device is installed on the buoy to enable it
  电铃头压紧通气孔,以保证焊接过程中通气孔的位置不移动。首先,将第一道焊缝与通气孔焊接在波纹管上,然后进行第二道焊缝,将通气孔与通气孔焊接在通气孔上。管焊缝铸件的防渗性要求较高,但眼板焊缝o要求完全穿透。
  The bell head compresses the air vent to ensure that the position of the air vent does not move during welding. Firstly, the first weld and the air hole are welded on the bellows, then the second weld is welded, and the air hole and the air hole are welded on the air hole. The impermeability requirement of pipe weld casting is high, but the penetration requirement of eye plate weld O is complete.
