Most of these problems by reducing the welding speed, weld width sufficient to ensure solution. However, when considering the efficiency and cost, this solution will not work. Solve the above problem of a high-speed welding is by adjusting the shape of the weld penetration: increasing the weld width. Increase will reduce the width of weld seam discontinuity, improved weld quality, particularly for welding sheet metal. Welding quality can be achieved by further reducing the welding slag, slag will peel because the weld coating.
In order to achieve these requirements, Kobe Steel of Japan (Kobe Stee) developed a new GMAW Welding Wires wire: SE-A50FS, can form a wide welding seam, resulting in minimal slag. The company also developed a variety of methods to control its weld pool characteristics.
GMAW welding applications using the new
GMAW welding wire manufactured shape appearance, less slag, is ideal for automotive and electronics industries sheet (2 ~ 4mm) corner of the lap joint and T-joint welding. The wire is also suitable for mixed-gas (Ar and CO2) welding.
The project focuses on analysis of the CO2 gas Aluminium Welding Wire process in the electroless copper wire drawing attachment status, before the acid wash quality plating, chemical plating solution composition, etc. on the wire surface of the copper layer adhesion, color quality, impact, and thus the corresponding gas-improved electroless copper wire production line process, so that the quality of copper wire after the national standard (GBT/41100-95) in 5.6.1 and 5.6.2 requirements.
Main features: 1. To improve the composition of electroless copper plating solution, thereby increasing the binding force of the copper layer and the surface color. (2) pre-treatment process to improve copper plating, electroless copper plating to ensure quality. 3 finishing polishing speed 160-180m/min. 4 alkali, acid wash lotion effective life of more than 30 tons Welding Wire China . 5 copper coating adhesion can not afford to scale up without peeling off layers of copper, the copper layer thickness ≤ 0.5um. 6 finishing polished surface, uniform color, has good corrosion resistance.
For field welding.
