摘要

爆炸复合钢板的关键工序是爆炸复合、热处理、覆层拼接及未结合补焊。介绍2205+Q345C双相不锈钢复合钢板的爆炸焊接工艺,通过控制板间距、炸药配方、炸药密度及厚度、地基等方面,获得了理想的结合质量。为消除爆炸焊接应力,通过选择合理的热处理工艺,复合钢板既获得了基材良好的力学性能又保证了覆层优异的耐腐蚀性能。同时,为满足标准或技术条件要求,通过控制覆层的拼接和未结合区域补焊的质量,获得了优良的焊缝性能。从而保证了2205双相不锈钢复合板的力学性能、耐蚀性、相比等均满足技术要求。

Abstract

The key process of explosive clad steel plate is explosion compounding,heat treatment,splicing and uncombined area repair welding.Introduce the explosion welding technology of 2205+Q345 C duplex stainless steel,obtaining the ideal bonding quality by controlling the plate spacing,explosive formulation,explosive density,thickness,foundation and so on.Selecting a reasonable heat treatment process to eliminate the explosion welding stress,and also obtain good mechanical properties of the substrate and ensure excellent corrosion resistance of the coating.Meanwhile,in order to meet the requirements of the standard,through the quality control of the splicing of the coating and the repair of the uncombined area,excellent weld performance is also obtained.Thus,the mechanical properties,corrosion resistance and comparison of the 2205 duplex stainless steel composite plate meet the technical requirements.
