용접구조용 극후판강재의 인성에 관한 연구 (2) - 전기로후판강재의 용접특성 ( A Study on the Weldability of the Thick Plates Processed in Electric Furnace )

The purpose of this study is to examine the welding characteristics of the plates processed in eletric furnace. A series of experiments has been carried out, which includes tension test across the weld; Y-groove weld cracking test; impact test in the room temperature; and bending test. The final results of the experiments show that the electric furnaced plates meet the Korean Standards in the ultimate strength and the impact values. In addition, the electric furnaced plates of 100mm have shown the crack of welds in bended parts.
