At present, most of the anode aluminum rod and anode yoke of electrolytic aluminum enterprises mainly use explosive welding for transition connection. According to incomplete statistics, the annual cracking rate of the anode rod explosive block using traditional explosion welding method is 16-18%, because the traditional welding method is difficult to guarantee the welding quality at the welding joint, and the joint voltage drop is high, which leads to huge energy loss. Therefore, it is particularly important to introduce reliable and efficient steel and aluminum welding technology to reduce maintenance costs and electrolytic production costs.

Aiming at the current situation of the use of explosive welding block, in order to solve the above problems, Jingwei Technology, after in-depth research and a large number of experiments, has developed the JW-51A steel and aluminum welding process and the supporting steel and aluminum welding production line, which realizes the welding of  anode rod and anode beam without the need for explosive welding block, and the quality of the weld is more reliable and stable. Since the technology entered the field application in 2015, it has been put into application in many electrolytic aluminum enterprises such as Aluminum Corporation of China ,Baise Yinhai, Gansu Zhongrui, Neimeng Jinlian, Xinjiang branch of East Hope , Xinfa Group, etc. The use effect is good, and the power saving advantage is obvious.

Jingwei Technology has an independent invention patent for the direct welding method of aluminum steel with anode aluminum rod and anode yoke ( patent number: ZL 2018 1 0334065.8);

Since the aluminum steel direct welding process was put into use in Baotou Enterprise of China Aluminum Co., LTD in December 2017, more than 20 units have been used nationwide. Aluminum steel direct welding has been applied in cells including 240KA, 300KA, 400KA, 500KA, 600KA and so on. And the use of aluminum steel welding rod group structure covers all existing domestic structural forms such as: 4 claws, 6 claws and 8 claws, stub material including structural stub and cast stub. From normal anode change to the start of the new potlines, it has been applied in a variety of application scenarios of electrolytic production process, and the effect is good.

The equipment has a high degree of automation, and the transfer, processing and welding process of the workpiece can be networked and automated.

• Aluminum steel direct welding method can be used instead of explosive welding block, saving maintenance cost and reducing voltage drop of welding joint.
• Robotic automatic welding can be used instead of manual operation.
• Automatic transfer of equipment can be used instead of crane and forklift transfer to improve the automation level of equipment in the plant and reduce labor intensity.
