Description

Welding equipment and process for motor fan covers Technical Field

[0001] This invention relates to the field of welding equipment for motor fan covers, and more specifically to a welding equipment and process for motor fan covers. Background Technology

[0002] A motor shroud is a cover used to protect a motor. It effectively prevents external dust, liquids, and other contaminants from entering the motor and also prevents accidental electric shock. Furthermore, motors generate a large amount of heat during operation. If this heat cannot be dissipated in time, the motor temperature will rise, reducing its lifespan. A motor shroud has excellent heat dissipation capabilities, quickly expelling the internal heat and keeping the motor within a suitable temperature range, thus ensuring normal operation. A motor shroud typically consists of an annular tube and a perforated cover plate. The annular tube and cover plate are welded together. However, some motor shrouds also have reinforcing ribs, which are welded to the annular tube and cover plate. Due to the large number of reinforcing ribs, their interaction during welding can cause the ribs to tilt towards the cover plate, resulting in large gaps between the ribs and the annular tube. This requires additional welding, affecting the processing quality. Therefore, this paper proposes a welding equipment and process for motor shrouds. Summary of the Invention
