摘要:
为了制定合理的热处理方案,以适应海洋工程D36钢焊接施工要求,保证焊接质量,在母材、焊材、坡口形式、焊接位置、焊接方法及工艺等基本参数一致的条件下,对不同热处理温度下D36钢焊接接头的焊缝和热影响区的化学成分、力学性能和金相组织进行了分析和对比试验。结果表明,热处理温度的不同会导致焊缝区和热影响区的显微组织发生较为复杂的变化,进而使焊接接头的力学性能下降,为了保证焊接质量应该选择合适的热处理温度。经测定,780 ℃和890 ℃热处理条件下焊接接头的金相组织和力学性能都在规定范围,但780 ℃热处理后焊接接头的力学性能更为优异。
Abstract:
In order to formulate a reasonable heat treatment scheme to meet the requirements of welding construction and welding quality, under the condition of the basic parameters are consistent, such as base metal, welding material, groove type, welding position, welding method, welding technology, and so on, the chemical composition, mechanical properties and metallographic structure of D36 steel weld and heat affected zone were analyzed and compared under different heat treatment temperature. The results indicated that different heat treatment temperature can lead to complex change in microstructure of weld and heat affected zone, and then the mechanical properties of welded joint reduce, so it should select the appropriate heat treatment temperature to ensure welding quality. After measurement, the metallographic structure and mechanical properties of welded joint are within the specified scope under 780 ℃ and 890 ℃ heat treatment temperature, but after heat treatment at 780 ℃, the mechanical properties of welded joint is more excellent.
