摘要
由于在钛钢复合板焊接时,容易引起复层钛板与基层碳钢互熔的现象,所产生的中间化合物是脆性组织,破坏和改变了原有金属晶格,二者不具有良好的异种金属的焊接性,所以在接头设计及技术措施制定中都需要采取特殊的施工方法,从而保证钛钢复合板的焊接质量满足设计要求。结合火电厂烟囱内筒钛钢复合板的焊接试验研究与施工过程控制,对该焊接技术进行了较为系统的介绍。
Because the welding of the titanium steel composite plate easily causes the mutual melting between compound layer of titanium plate and the base steel, the resulting intermediate compounds are brittle microstructure, which can damage and change the original metal lattice, the two do not have good welding of dissimilar metals, so the joint design and technical measures are required to take special construction methods, thus ensuring titanium steel composite plate welding quality to meet the design requirement. Combining the test and construction of process control of thermal power plant chimney inner cylinder welding of titanium steel composite plate, the welding technology is introduced.
