U对焊机N系列闪光闪光对焊的主要焊接工艺及原理：1・焊接电极加紧工件，在工件尚未完全接触时，开始闪光2. 接下来，焊接电极夹紧的工件缓慢接近，随者电流密度的增加，1：件间接触处开始胳化，同时有部分金 属胳液溢出，形成初始的对焊节点3. 焊接区域变得越来越热，对焊的速度也随若加速4 .闪光和飞溅使两个接触面完全焊接在一起5.最后再利用高压进行顶锻，切断电流，焊接完成主要应用领域：1 .各种餐具，厨房和餐具刀具的焊接；2. 自行车，摩托车，汽车车圈，及其他金属环的对焊；3. 各种金属幺幻金属带，铁棒，建筑用钢筋对焊：4. 各种圆管，方管的形与T形焊接:5 .窗框与门框的对角焊接主要技术参数:参数额度额度电压额定频率最大 短路 电流负载持续率最大加紧力最大 顶锻 力冷却水流M：：平均重量外形尺寸型号UN-5050KVA380V/420V50/60Hz19000A50%4000N2000N150L/H35OKg100*90* 150CMUN-7575KVA380V/420 V50/60Hz24000A50%6500N3000N150L/H450Kg100*90* 150CMUN-100100Kv.\380V/420V50/60Hz28000A50%6500N3000N150LZH55OKg100*90* 150CMUN-150150KVA380V/420 V50/60Hz32000A50%85OON4000N300UH1200K g140*100*170CMUN-200200KVA380V/420 V50/60Hz37000A50%85OON4000N300UHHOOK g140*100*170CMUN-250250KVA380V/420 V50/60Hz45000A50%12000N6000N600L/H1600K g180*120*190CMUN-300300KVA380V/420V50/60Hz52000A50%12000N6000N600L/H1800K g180*120*190CMUN Series Pneumatic Flash Butt WelderThe Main Principle of UN Series Pneumatic Flash Butt Welder:1 .The flash butt process starts when the two workpieces to be welded which are clamped by welding jams still not meet each other.2. During the subsequence,move the welding jaws together slowlyjhe welding current density will increase,then the metal material in the gap between the jaws becomes molten,at the same time a shower of sparks also being emitted.3. As the cross-sectional area in the welding becomes extremely hot^the motion is accelerated.4. The flashing also makes the surfaces to welded together totally.5. Finally the upset occurs at high pressureJhe welding current is cut off.Typical Applications:1. A11 kinds of dinnerware,cooking knives and table knives;2. Bicycle rimjnotorbike rim,car rim,or similar strip rings;3. Various metal wire and steel strip,construction steel bar and rebar;4. Round.Sqiiare and Rectangular tubes welding into "L" or "T" shape;5. Mitre welding of door and window frames.Main Technical Parameter:Para meterRate d Pow erRated Voltag eRatedFrequ encyMaxShor tCur rentRatedDutyCy cleMaxClam pingForceMax Upse tting Fore eCool ing WaterRequ iredWei ghtOverDimensio nsL*W*HModeINo.UN-7 575KVA380V/420V50/60Hz24000A50%6500N3000N150L/H450 Kg100*90*150CMUN-100100KVA380V/420V50/60Hz28000A50%6500N3000N150L/H550Kg100*90*150CMUN-1150380V/50/603205()85004000300L120140*100*50KVA420VHz00A%NNZHOKg170CMUN-200200KVA380V/420V50/60Hz37000A50%8500N4000N300L/H140OKg140*100*170CM。
