Title:
METHOD FOR WELDING STEEL, AND MANUFACTURE OF STEEL
Document Type and Number:
Japanese Patent JPH08108282
Kind Code:
A
Abstract:
PURPOSE: To improve the efficiency of the arc welding of steel, and to provide an excellent large steel structure member with improved quality of the heat- affected zone.
CONSTITUTION: The steel of 800-1400°C in temperature and 10-200mm in thickness is welded by the gas shielded arc welding method or the submerged arc welding method with the condition of 10-60mm in the groove root face, and 3-30kJ/mm in the heat input. The steel of high temperature can be efficiently welded by the large heat input welding, and the amount of the welding material can be reduced. The steel whose weld zone is assimilated to the base metal can be obtained by rolling the welded steel.
