Submerged Arc Welding Machine

The submerged arc welding machine is mainly used for submerged arc welding of assembling finished box girder. The backing welding and electroslag welding (ESW) finished box girder will be transported to the processing station of submerged welding. It is put on the work frame with welding seam side up. The lifting welding arm equipped with submerged welding torch, wire feeding machine, welding seam tracking frame etc. can do horizontal and vertical movement on the cantilever beam through adjustment. The welding nozzle of the welding torch should be aimed at the welding seam. Then start the welding machine, and the machine will travel straight along the rail, thus realizing automatic welding of the box girder welding seam.

Technical features
The submerged arc welding machine has the following features

1. Each group of welding arm is equipped with double arc double wire welding head. The wire feeding machine of the welding machine is installed on the top end of the welding arm, while the welding torch and mechanical tracking device is installed on the bottom end of the welding arm.
2. The welding arm adopts chain drive and weight tension device, so that it has good performance in floating tracking.
3. The horizontal tracking adopts cylinder press and is compensated in order to ensure the tracking of welding seam effectively.
4. The submerged arc welding machine adopts AC frequency speed control, so that it has large range of speed adjustment which can meet the demand of different welding speed. It has fast return stroke and stable running.
5. The machine also has the following features: simple operation and convenient maintenance.
