Another way of Copper Electrode gas welding, manual carbon arc welding, manual arc welding and manual argon arc another way, the large-scale structure can also take the initiative welding. (1) copper gas welding Welding copper is most often used in the docking discussion, lapping discussion and discussion of T to take as little as possible. Welding can take two wires, one wire containing deoxy elements, such as wire 20, 202; another red copper and base metal cutting, take the gas agent 301 as flux. Welding copper to be taken to a neutral flame. (2) copper manual arc welding Taken in manual arc welding of copper 107 copper electrode welding core of copper (T2, T3), The edge of the weld should be cleaned before welding. Weldment thickness greater than 4 sister before the welding necessary to preheat, the preheat temperature is about 400 ~ 500 ℃. 107 electrode with Copper Electrodes, the power should be taken to the DCRP. When they should be short-arc welding, the electrodes are not suitable for lateral oscillation. Electrode for exchanges between the straight-line activities can improve weld forming. Long weld should be taken to gradually retire welding method. Welding rate should be faster. Multi-pass welding, it is necessary to completely remove the slag layer. Welding should be carried out in well-ventilated places, to provide protection against copper poisoning. The use of flat mallet percussion weld after Welding Electrode to eliminate stress and improve weld quality.
Tonight and friends go to night market, are aimlessly looking into a shop selling clothes do not feel anything, and suddenly feeling store songs so all of a sudden very spirit of the original song of ELVA, < miss Christmas, Christmas is coming, a lot of stores sell packaged apples, slow response of friends, and asked my original Christmas ah, sweat, my teenage gap. Huh, huh.
Last night for dinner, her husband mysterious smiling wife approaching Christmas I gave you a gift, although not very good, is a meaning on the line. . . Well, although her husband most of the festivals are more consciously prepared gifts gifts, but he suddenly gave me something to feel a little excited. But when he took out to take the hat, my face is estimated must be a 180 degree shift, picked up with a photo of a mirror, and flew still side, said that does not look good, color does not like. . . . God, think of his face changed fast because my words are too sharp and broke his heart, leading to his angry hat back together, angrily said, do you think I bought you God. I am not. . . . . Although I nothing cheeky night looking for him to speak, not to mention the hat thing, but they are not comfortable heart. So ten hours later. During the day, I suddenly thought of one thing, their own sobering.
Then go to school, we did not make money, her husband is always the money deducted from the cost of living, occasionally surprise me, that time is not money to buy things I cherish, I am glad. I remember a weekend with him and come out to play from his pocket and took out several "rings", as the ring to do with colored wires, the middle of the junction with the Carbon Steel Welding Electrode together, like a gem, clung to it, he said he was on the electromechanical electronic course do nothing to me, with soldering, Welding Electrode in the integrated version of my name intentions point out, each shape is a tin solder, get out of so much have to weld the number of points , when the "ring" wear I should feel like the happiest woman in it. Many gifts that he has done now I have it, because that is our witness. I kept thinking, so back memories, yes ah, then there is no money, there is no material desire, no job, no mature, has a pure feeling, not mixed anything. Now, money, got a job, mature, but find fault with the material as part of each other to measure love, so many people are around to see the material is too important, to show off their wealth as a sign of self-confidence, suddenly afraid he could not become such a person, and this continues, it will only hurt the dearest people around, get lost, so that life has no taste.
Listen the the ELVA songs, listening to the miss Christmas, listening to the bell ringing songs, Dangdang when it is not Christmas, but this is my Christmas, baby Merry Christmas. Outside stop lying fireworks inside the house and the same warm heart.
