Abstract
The welding of 16 mm thick S355J2G3 low alloy steel plate is analyzed in terms of the proper mix gas arc welding procedure and the corresponding welding joint performances
and the it proves high quality welding joint based on the welding procedure qualification test. According to practical production
the reasonable welding procedure is made and applied to the tank welding of large converter transformer
which extends the lifetime of converter transformer tank with high strength welding structure.
