Abstract
The study examined microstructural factors in the MIG/MAG welding process of 3 mm and 4 mm industrial steel, leading to failures in 500 KVA power transformers. Charpy-V impact tests and microstructural analysis were conducted to correlate microstructure with impact toughness. Results revealed impurities in the weld pool, affecting weld quality and causing leaks of insulating oil.
