补充资料:焊接线能量
焊接线能量
energy input
hanJ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)
