Title:
PROCESS METHOD FOR WELDING LOW-TEMPERATURE DUCTILE IRON AND MANGANESE STEEL PLATE
Document Type and Number:
WIPO Patent Application WO/2018/036130
Kind Code:
A1
Abstract:
A process method for welding a low-temperature ductile iron and a manganese steel plate, the method comprising: selecting a NiFe-1 welding rod, and using an MAG active gas shielded welding process to weld the low-temperature ductile iron material and the manganese steel plate together in an intermittent welding manner, wherein the low-temperature ductile iron material, the manganese steel plate and the welding rod are neither preheated before welding, nor are they subjected to a heat treatment after welding. The welding process not only results in a good fusion at the root of the weld, a good weld profile formation, no crack on the surface, no blow hole and no embrittlement and crack phenomenon to the low-temperature ductile iron material, but also causes the quality of the manganese steel plate not to be reduced; furthermore, the energy consumption is saved.
