焊接线能量焊接线能量energy inputhanJ一ex一an nengllang焊接线能量(Energy Input)由移动热源输入给单位长焊缝的能量。焊接线能量是焊接过程中各种热现象的重要影响因素，它不但影响峰值温度的分布和冷却速度，还影响凝固时间，从而影响金属焊接接头的冶金特性和力学性能。其计算式为H~尸/v，式中H为线能量，J/mm;尸为由热源输入的总能量，W;v为热源移动速度，mm/s。若热源为电弧，则H~El/v，式中E为电弧电压，V;I为焊接电流，A。若要精确计算热源对焊件的作用，则Hne，~人，El/v，式中Hne:为净得线能量。fl为热传导系数，其值为实际传给工件的热能与热源产生的总能量之比。热影响区的宽度与H二:成正比，焊缝的冷速与H、，成反比，而凝固时间与之成正比。所以焊接线能量对金属焊接性有一定的影响。 (李维茜)
