Abstract

This paper aims to analyse the application, importance and impact of heat treatment operations used in ferritic stainless steel welding processes on the properties of the welds obtained. In addition, the article aimed to formulate the main problems that occur during the welding process of ferritic stainless steels, including, in particular, the phenomenon of ferrite grain growth due to thermal processes.The analysis of the available literature covered issues related to heat treatment processes used in the welding of ferritic stainless steels, taking into account the issue of the growth of the ferrite grain under the influence of heat supplied during welding and the possibility of heat treatment of the obtained welds. The analysis also included determining the possibility of inhibiting the growth of ferrite grains by using elements such as titanium, niobium, and molybdenum, thus improving the strength properties of welds.Organisation of knowledge in the field of the impact on the mechanical properties of ferritic stainless-steel welds and heat treatment processes used before, during, and after welding.Properly selected parameters of the welding process of ferritic stainless steels, especially the amount of heat input, together with appropriate heat treatment parameters, should improve the mechanical properties of ferritic stainless steels.The analysis of the possibility of a wider application of ferritic stainless steels allowed to draw one of the main conclusions stating that the limited possibilities of using ferritic stainless steels in heavy industry are related to their high susceptibility to ferrite grain growth under the influence of high temperature during welding and, consequently, decreases in strength properties of welding joints made of ferritic stainless steels. Additional heat treatment operations are introduced before, during, or after the sapping process to improve their mechanical properties.

热处理在铁素体不锈钢焊接工艺中的应用——原因及影响

本文旨在分析铁素体不锈钢焊接工艺中热处理操作的应用、重要性和对焊缝性能的影响。此外，本文旨在阐述铁素体不锈钢焊接过程中出现的主要问题，特别是由于热过程导致的铁素体晶粒长大现象。对现有文献的分析涵盖了与铁素体不锈钢焊接中使用的热处理工艺有关的问题，考虑到铁素体晶粒在焊接过程中所提供的热量影响下的生长问题以及对所获得的焊缝进行热处理的可能性。分析还包括确定使用钛、铌和钼等元素抑制铁素体晶粒生长的可能性，从而提高焊缝的强度性能。对铁素体不锈钢焊接机械性能的影响以及焊接前、焊接中和焊接后使用的热处理工艺的知识组织。适当选择铁素体不锈钢的焊接工艺参数，特别是热输入量，加上适当的热处理参数，应能改善铁素体不锈钢的力学性能。通过对铁素体不锈钢更广泛应用的可能性的分析，得出了一个主要结论，即在重工业中使用铁素体不锈钢的可能性有限，这与它们在焊接高温的影响下对铁素体晶粒生长的高度敏感性有关，因此，铁素体不锈钢制成的焊接接头的强度性能下降。在切割过程之前、过程中或之后引入额外的热处理操作，以改善其机械性能。
