从自保护药芯焊丝合金元素角度出发，探究了自保护药芯焊丝半自动焊焊缝冲击性能不稳定的主要影响因素。采用两种不同Cr含量的自保护药芯焊丝对同一种钢板进行焊接，对获得的焊缝金属进行了夏比冲击性能检测和金相组织分析，探究了合金元素Cr对自保护药芯焊丝半自动焊焊缝组织及冲击性能的影响。分析结果表明：焊丝中Cr含量较高的焊缝冲击功离散性大，且焊缝中链状M/A含量高。
從自保護藥芯銲絲閤金元素角度齣髮，探究瞭自保護藥芯銲絲半自動銲銲縫遲擊性能不穩定的主要影響因素。採用兩種不同Cr含量的自保護藥芯銲絲對同一種鋼闆進行銲接，對穫得的銲縫金屬進行瞭夏比遲擊性能檢測和金相組織分析，探究瞭閤金元素Cr對自保護藥芯銲絲半自動銲銲縫組織及遲擊性能的影響。分析結果錶明：銲絲中Cr含量較高的銲縫遲擊功離散性大，且銲縫中鏈狀M/A含量高。

From the perspective of self-shielded flux cored wire alloying elements, it explored the main influence factor on unstable weld impact performance of self-shielded flux cored wire semi-automatic welding. Adopting two types of self-shielded flux cored wire with different Cr element content to carry out welding on the same steel plate, the Sharpy impact performance test and microstructure analysis were performed for the obtainedweld metal, and the effect of Cr alloying element on impact performance and microstructureof self-shielded flux cored wire to semi-automatic welding was explored. The result indicated that the weld containing high Cr content is with large discreteness, and chain M/Acontent in the weld is high.
