求助(关于焊接方面的)? electrodes drying/conditioning 焊条的烘干/抽湿处理。烘干/抽湿是一回事,都是指焊条放在烘箱里烘培,去掉水分,所以用/(代表“或者”的意思)。 re-drying/ conditioning all electrode coatings are hydroscopic and, when left in the opened state for a period of time will absorb moisture. austenitic materials are generally insensitive, to the presence of hydrogen. however, moisture in the electrode coating can lead to porosity in the weld metal. start porosity is generally indicative of damp electrodes and is more common in fillet welds than in butt welds, where pores only occur at high moisture contents. electrodes that have been stored outside of their hermetically sealed cans and have become damaged by moisture pick-up, can be redried at temperatures of 300–350°c for 1–2 hours. redrying should be restricted to a maximum of 3 cycles.查看更多
