铝合金薄板焊接热裂敏感性探索
Investigation on Welding Heat Cracking Susceptibility in Thin Plate of Aluminum Alloys
【摘要】 探讨了用钨极氩弧焊焊接铝合金ＬＹ１２ＣＺ及ＬＹ１２Ｍ薄板时其热裂纹的变化规律，并分析了焊接工艺参数及填充材料对热裂纹的影响。试验结果表明，选择合适的工艺参数和填充材料可以明显提高该类合金的抗裂性能。
【Abstract】 The rules which influence the welding heat cracking of aluminum alloys LY12CZ and LY12M with GTAW are respectively investigated. The influence of welding technological parameters and filling materials on heat cracking is analyzed. The experimental results show that suitable filling materials and welding technological parameters will obviously improve the cracking resistance properties of these alloys.
