焊接結构强度在焊接的应用与发展中占有重要地位,高强度的焊接結构保証了結构的安全使用与耐久。目前各国在这方面进行着大量的研究工作,并初步得出設計及工艺等因素对焊接結构及接头强度的影响。但是,对它們全面的分析、充分掌握变化規律仍嫌不足,人們还不能从已有的資料中直接地、准确地推測出各种焊接結构与接头在不同載荷与使用条件下的强度,这样,焊接結构强度仍为一个未解决的問題。
The strength of welded structure occupies an important position in the application and development of welding. The high-strength welded structure ensures the safe use and durability of the structure. At present, a great deal of research work is carried out by all countries in this field, and the influence of design and process factors on the strength of welded structures and joints has been initially shown. However, it is still not enough for them to make a comprehensive analysis and fully grasp the changing laws. Therefore, people can not directly and accurately infer the strength of various welded structures and joints under different load and use conditions from the existing data, Welded structural strength remains an open problem.
