Description

Technical Field

[0001] The invention belongs to the technical field of welding devices, and in particular relates to a laser positioning welding device for a large marine generator set. Background Art

[0002] In the shipbuilding industry, large marine generator sets are core equipment for ship propulsion systems and power supply. Their manufacturing precision and welding quality are directly related to the stability and safety of ship operation. At present, for the welding of large marine generator set components, laser positioning welding technology has become the mainstream process in the industry due to its high precision and high efficiency. This technology uses laser scanning to locate welds in real time, and combines an automated control system to drive the welding gun to complete welding, effectively improving welding efficiency and weld quality.

[0003] However, the existing laser positioning welding equipment for large marine generator sets has significant safety hazards in actual application. Since the welding process is completely exposed to an open environment, the high-intensity arc generated during welding will cause serious harm to operators and surrounding personnel. Prolonged exposure to arc light may cause health problems such as photoelectric eye inflammation, skin burns, and decreased vision, and even cause permanent damage such as cataracts. Although some equipment is equipped with basic protective measures, such as welding masks and radiation-proof work clothes, these measures can only protect the operators themselves and cannot eliminate the potential threat of arc light to surrounding personnel. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a laser positioning welding device for large marine generator sets, which effectively solves the problem that the high-intensity arc generated during welding can cause serious harm to operators and surrounding personnel.
