The re-drying of the Welding Electrodes :
The electrode place for a long time from manufacture to use hygroscopic, Welding Materials  core does not rust and not degenerate drug skin electrodes after drying, to ensure the original performance. Drying temperature according to the electrode manual provides low temperature up to less than the purpose of removing moisture, excessive easily lead to the decomposition of the binder drug skin cracking, welding, melting into the crack at the close, resulting in the shedding phenomenon As the baking temperature increases, the alloy element within the drug skin oxidation, the influence of the transition of the alloy. Electrode drying generally use a dedicated oven with automatic temperature control, should take and how much baking how much, with the drying with the principle, after drying in the outdoor dew put no more than four hours, the electrode layers stacked in an oven Φ4mm not more than three layers, Φ3.2mm no more than five or stacked thick cause uneven temperature, local overheating of the drug skin off. The drying box must with a row influx device. The number of re-drying, and can generally be repeated 2 times, more than two times to solicit the views of the welding rod factory.

LiNO_3-KNO_3 aluminum electrode in the electrochemical behavior of molten saltUsing cyclic voltammetry and constant potential electrolysis aluminum electrodes investigated in LiNO3-KNO3 molten salt electrochemical behavior . Experimental results show that in the molten salt , Lithium ions in the aluminum electrode electrochemical reduction process with the new ecology of lithium atoms to the electrode inside the subsequent diffusion step ; lithium atoms into ALUMINUMAfter the occurrence of highly alloyed with Aluminum Electrodesto form a β-LiAl alloy and γ-LiAl alloy ; lithium ion in the aluminum reduction process on the electrodes of lithium by the reduced stateSteps to control the spread of the aluminum body . Cyclic voltammetry experiments found that aluminum electrodes in the molten salt oxidation and reduction peak currents are first increased with the number of cyclesPlus increases , and finally basically stable , suggesting that the aluminum electrode Molten salt has good electrochemical stability .
