AI Technical Summary
Existing weld quality evaluation methods mainly rely on qualitative analysis, which makes it difficult to effectively detect weld uniformity and defects such as porosity and stress concentration. Moreover, conventional methods are mostly non-destructive or destructive testing, which cannot comprehensively assess the weld uniformity and potential defects.
By heating and oxidizing the weld, combined with oxidation depth and hardness testing, stress concentration is released, crack-like defects are characterized, and weld uniformity is judged by the difference in oxidation depth and weld hardness changes, thus achieving the evaluation of weld composition uniformity.
This paper presents a simple and quantitative method for evaluating weld quality, which can more easily detect defects such as delayed cracks, improve the accuracy and comprehensiveness of weld uniformity assessment, and is applicable to weld quality analysis of various welding methods and materials.
