摘要
本文在分析中厚钛材焊接性和焊接工艺方法的基础上,选择适于中厚钛材的焊接工艺。采用20mm厚的工业纯钛进行焊接工艺试验,通过试验及结果分析,大电流氩弧焊、等离子弧焊组合工艺及钨极深熔氩弧焊,配合合适的坡口结构,是适用于中厚钛材焊接经济、实用、高效焊接方法。三种焊接工艺完成的焊接接头性能和质量满足压力容器规范要求。
Based on the weldability and suitable welding processes for titanium plates,select the applicable welding procedure for titanium plates. Pure titanium plates with a thickness of 20 mm is used for welding procedure test. Analysing testing process and results,we can find the big current GTAW,PAW + big current GTAW,tungsten deep fusion argon arc welding with applicable groove type are economic,practical,high effective way of welding procedures for titanium plates. Mechanical property and quality of welded joints made by the selected three welding procedures comply with the requirement of pressure vessel codes.
