METHOD FOR WELDING BUTT WELDING SECTION OF CLAD STEEL PLATE

摘要

PURPOSE: A method for welding a butt welding section of a clad steel plate is provided to reduce welding time and to improve productivity by welding the butt welding section through an electro slag welding process. CONSTITUTION: A clad steel plate(10) includes a corrosion-resistance steel plate(12) and a lower steel plate(14). A welding section(24) of the lower steel plate(14) is firstly welded. After that, a flux(22) is coated on a clad butt welding section(16) in order to protect the clad butt welding section(16). In this state, an electro slag welding section(26) is formed on the clad butt welding section(16) of the corrosion-resistance steel plate(12) through an electro slag welding process by using a strip welding material(18). When the welding process is completed, a slag is removed from the clad butt welding section(16).
