technical field

The invention relates to the field of welding in the machinery manufacturing industry, in particular to an automatic welding device for connecting pipes of parallel flow tube condensers.

Background technique

Condenser tube welding is a key process in the condenser manufacturing industry. The connecting pipes vary in shape and size due to different uses. The connecting pipes of parallel flow tube condensers are usually in the shape of an "L", and the material is half aluminum and half copper. The aluminum part is welded to the condenser, and the copper part is the refrigerant charging channel. . Traditional pipe welding is usually artificial flame welding, because the structure of the condenser itself is complex, the device for fixing it and the pipe is relatively complicated, the clamping and disassembly process takes a long time, and the symmetry and overall parallelism between the pipes after welding cannot be guaranteed; in addition Aluminum products have a low melting point, which is easy to miss welding and weld through the workpiece, which requires high technical requirements for welding personnel.
