电焊条先将配方中的各项原材料的主要成分分别乘以配方百分比，单独得出单项原材料的 主要化学成分在实际设计配方中的占有值，然后将各项原材料的同类相化学成分逐一相 加，其总和是实际配方中的主要组成成分。并用分子理论计算出碱度，估计工艺性。可 用合金过渡系数，来分析焊缝金属的机械性能和化学成分。 式中 η—某合金的过渡系数 W—合金元素在熔敷金属中的实际含量（%）

First the formula of the wire the raw material of the main ingredients are multiplied by formula that percentage, alone the raw material of the single main chemical compositions in actual design of the formula has value, and then the raw materials of the same kind in the chemical composition in the sum, one with actual formula is the main components. Molecular theory and calculated, estimate the basicity manufacturability. Can use alloy, to analyze the transition coefficient of the mechanical properties of the weld metal and chemical composition. Type in a transition η-alloy alloy elements W-coefficient in the actual content deposited metal melting (%)
