The Study of Full Penetration Welding between Corrugated BHD and Lower Stool Joint by Application of CSR

CSR 적용에 따른 Corrugated BHD와 Lower Stool Joint의 Full Penetration Welding 적용에 관한 연구

CSR(Common Structure Rules) enter into force on $1^{st}$ April 2006. Generally for double hull tankers of less than 150m in length, the Rules of the individual Classification Society are to be applied. Where high tensile stresses act through an intermediate plate, increased fillet welds or penetration welds are to be used longitudinal/transverse bulkhead primary support member end connections to the double bottom. If workers have begun to make used of established procedures between corrugated BHD and lower stool joint, first to welding on groove of face and then it has to gouging to blow on groove of root. So amount of man-hour increased, productivity secreased.
