Select welding equipment currently on the market more types of welding products, under normal circumstances should AC GTAW (TIG welding that is). It is under the protection of argon, the use of tungsten electrode and the workpiece mother asked the arc generated hot melt A welding material and filler wire method. When the welding work, due to the polarity of the alternating current in periodic transformation in each half wave cycle DCSP, half-wave DC reverse. are connected in half Tungsten can emit enough electrons during a wave of overheating but Buzhi Yu electronic aluminum foil Which is good, conducive to the stability of the arc. oxide film reverse surface of the workpiece during the half-wave generated can easily be cleaned up and get beautiful bright surface, forming good weld. 1, pretreatment, prior to use of the surface cleaning, using physical and chemical methods are the most important is the aluminum coil is exposed substrate. Thus, it helps complete the oxidation of the formed oxide film will be dense. pretreatment can also use some mechanical handling equipment. 2. anodized aluminum after processing through the coil, the matrix anodic oxidation occurs, then that will generate a dense oxide film. 3. Electronic sealing foil, after anodizing supply electronic foil manufacturers, will be a lot of membrane pores on the oxide film, sealing films is to make these holes closed to prevent contamination of the oxide film. This oxide film is transparent electronic foil manufacturers , but with adsorption, so that some metal will be deposited in the hole, so that we can reveal the appearance of some of the original silver-white, color or a lot of outside electronic aluminum foil |. Electronic foil spot Manufacturers | rolls of aluminum Aluminum Industry Co., Ltd. is provided by Jinan rolls. Jinan Heshun Aluminum Co. (www.jnhsly.com) in the field of aluminum products devoted boundless enthusiasm and passion, rolls Alcoa has been customer-centric, for customers to create the concept of value, quality and service to win market share sincerely hope to cooperate with the community to create success, create brilliant.
