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 material and a filler wire welding method when the welder working color coated aluminum coil Which is good, because the polarity of the alternating current in periodic transformation in each half wave cycle DCSP, half-wave DCRP. during the positive half wave pick of tungsten can emit enough electrons but Buzhi Yu overheating, 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 the surface bright and beautiful forming a good weld aluminum production and processing methods belong to the rolling process, also known as "rolling" process commonly used in two ways: the characteristics of hot-rolled and hot rolled casting method: In a large plastic deformation process, internal organization experienced a number of recovery and recrystallization of pre-painted aluminum coil manufacturers, will cast the state's crushing coarse grains, microscopic cracks healing color coated aluminum coil, the blank in uniform, grain size and shape of the internal organization, changes in the concentration of point defects and other casting defects and line defects are significantly improved, so that deformation cast organization into tissue, greatly improving the processing properties of the metal, especially in deep-drawing performance pre-painted aluminum coil manufacturer, Hot-rolled material has incomparable advantages casting material characteristics casting method: the internal organization of casting plate semi-cast structure, compared with a strong directional crystal hot-rolled, with less investment, low cost. high efficiency. color coated aluminum coil coated aluminum coil manufacturer _ _ cis Aluminum (View) provided by Jinan Heshun Aluminium Limited. Jinan Heshun Aluminum Co. (www.jnhsly.com) is a professional, "aluminum, aluminum, aluminum, aluminum rod, aluminum row, aluminum, aluminum, aluminum elbow" of the company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "aluminum, aluminum, aluminum, aluminum coil, aluminum rod" brand has a good reputation. We adhere to the "service first, customers first" principle, so that cis Alcoa won the trust of customers in all aluminum products, and establish a good corporate image.
