Porthole irrational, unreasonable diversion bridge design and processing. Should try to make the weld to the corners or decorative surfaces on a good quality aluminum cover panel Which, using drip-shaped bridge and shunt reasonable welding angle, so that the solder joints on the welding chamber falls flat (ie, pre-forming zone inside); if using "+ yu" bridge structural arrangement shunt hole, like this case supply aluminum cover panel manufacturers, middle of the bridge can be narrower, and Shen bridge (deepen local welding chamber depth) 5-8mm equipment and tooling Unlike precision welding of carbon steel, aluminum and stainless steel pipe for welding crew and demanding precision molds, license only run in a very small axial and radial runout. Larger periodic vibrations can cause welding defects. General requirements for precision control runout 0.01-0.03mm range. 4, high-frequency welding machines and plant operation control accuracy due to the small plastic range of aluminum and stainless steel materials, must be precisely controlled heat input during welding. Any large power fluctuations can cause weld slag and porosity produced. General requirements for the power output fluctuation of 1% or less good quality aluminum cover panel Which, rolls aluminum, aluminum cover panel provided by the Aluminum Co., Ltd. Jinan rolls. Jinan Heshun Aluminum Co. (www.jnhsly.com) Shandong Jinan, aluminum products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Aluminum leadership in cis with the staff warmly welcome all inquiries negotiations to create a better future for aluminum rolls.
