AI Technical Summary

Technical Problem

In the current production process of transformer oil tanks, manual welding results in high labor intensity, low efficiency, and a low production qualification rate, especially at the heat sink, where problems such as incomplete welding or weld burn-through are prone to occur.

Method used

An automated welding method is adopted, which utilizes a welding robot and an infrared seam-finding device to achieve automated welding of the cover, body and heat sink, including the automated welding of the magnetic shielding plate, positioning column and hanging plate. Positioning fixtures and flipping fixtures are used to improve clamping efficiency. The infrared seam-finding device adjusts the welding path in real time, and welding current control is used to achieve the overlay welding of the triangular area of ​​the heat sink.

Benefits of technology

It improves production efficiency, reduces the labor intensity of workers, ensures the stability and pass rate of welding quality, avoids problems such as missed welding and weld burn-through, and produces beautiful welds with good sealing performance.
