CONSTITUTION:In the DC TIG welding method, a filler 6 is on the side backward of the welding advance direction W and while it is being supplied in the arrow Y direction, its end is held dipped in molten pool 7. Here, the welding base metal 1 is made positive pole and a non-...
The process may employ direct current with positive or negative electrode or alternating current. In gerenal, AC is preferred for welding aluminum and magnesium. Direct current electrode negative is preferred for Welding most other materials and for automatic welding of thick aluminum. Thin magnesiu...
3.1 直流焊接与交流焊接 —直流TIG焊接 直流反接(DCRP/DCEP/DC+) :母材接负极 DCEP:direct current positive eletorde (ASME 美国机械工程师学会) DCRP:direct current reversed polarity (欧洲) DC+:不常见,多见于老企业内部、老教材 母材接负极,发射电子能力差,发热量小,焊道浅而宽,效率低,只用于焊接薄板?
(negative) and two-thirds at the anode (positive), the electrode is always negative polarity to prevent overheating and melting. However, the alternative power source connection of DC electrode positive polarity has the advantage in that when the cathode is on the workpiece, the surface is ...
DC reverse connection method: the weldment is connected to the negative electrode, and the tungsten electrode is connected to the positive electrode. When welding, the electrons rush to the tungsten electrode at high speed. The tungsten electrode has high heat and fast consumption, so it is gener...
TIG welding in AC (Figure 2B) allows the electrode positive (EP) portion of the cycle to blast away the aluminum oxide while the electrode negative (EN) portion melts the base metal. A feature called AC balance control allows operators to tailor the EP to EN ratio. If you notice a brown...
