Description

Technical Field

[0001] The utility model relates to the technical field of cladding machines, in particular to a cladding machine which is easy to move. Background Art

[0002] In steel production, continuous casting rollers are mainly used to keep the steel billets solidified. Under the effects of mechanical stress, thermal fatigue and metal wear caused by long-term use, the roller surface is oxidized and peeled off, which can easily cause cracks and breakage, posing problems with service life and safety hazards. In the prior art, surfacing is usually used to improve performance.

[0003] At present, when using a cladding welding machine, manual operation is required for welding. However, manual operation is prone to uneven movement speed. At the same time, when moving, the welding position is also prone to not being a straight line, resulting in the position that needs to be welded not being completely welded, thereby reducing the welding quality.
