Photoelectric cymometer of short-circuit transfer for gas shielded arc welding

光电式CO2气体保护焊短路过渡频率仪的研制

In view of the situation, high chromium alloys were deposited by the methods of flux-cored wire submerged-arc welding and self-shielded open-arc welding.

为此，本文优化合金系统，调节堆焊工艺参数以改变其碳化物等组织形态，采用药芯焊丝埋弧焊或自保护明弧焊方式，制备了高铬堆焊合金。

The assessment model has been proved reasonable from the fact that power factorial item of CO_2 gas shielded arc welding shows good comparability with correlative item of steel-making process in electric oven, which makes it possible to quantitatively assess the whole life cycle of materials.

获得的CO2气体保护焊的能源因子项与电炉炼钢工艺过程相关项有较好的相对可比性，这也表明该评估模型是合理的，并使得材料实现全寿命周期的定量评估成为可能。
