چکیده مقاله
In this study, the similar joint bonding of 430 stainless steel thin sheet was investigated using microplasma welding as this method has a high arc energy density, good arc stability, deep penetration, high metallurgical purity, and low heat affected area For this purpose, two thin sheets of 430 steel with a thickness of 0 3 mm were butt welded Then, the resulting microstructure and macrostructure were examined using a microscope and stereo microscope respectively Afterward, microhardness test was performed Examination of the resulting microstructure showed that by approaching the weld area from the base metal , the grains became coarser and also martensite was deposited between the grains, which increased the hardness in the area affected by heat and welding, and consequently reduced the toughness Examination of the macrostructure also showed that the molten metal grains of the weld pool grew epitaxially in directcontact with the base metal grains Keywords: Microplasma welding, ferritic
