Technical Field

[0001] This invention relates to the field of motor manufacturing technology, specifically to a motor casing welding device. Background Technology

[0002] The motor housing is a crucial component of an electric motor, primarily serving to protect the internal structure, support the rotor, and dissipate heat. The manufacturing quality of the motor housing directly impacts the motor's performance and lifespan. Structurally, motor housings are typically made of metal materials, with common materials including aluminum alloys and cast iron.

[0003] During the production of motor housings, welding machines are required to weld them. Traditional manual welding relies heavily on the operator's skills and experience, resulting in poor weld quality consistency and defects such as undercut, incomplete penetration, porosity, and slag inclusions. This leads to a high product defect rate, seriously affecting the mechanical strength and sealing performance of the motor housings, making it difficult to meet the quality requirements for motor housing production. Furthermore, manual welding is inefficient. Summary of the Invention
