â—† spot welding robot, arc welding robot Spot welding robots - The company currently uses a large number of the world's most typical robots such as COMAU, KUKA, and ABB. Regardless of the type of robot, the robot body has fewer faults, and most equipment failures are caused by the welding tongs and welding controllers installed on the robot arm. MIG welding machine - commonly known as carbon dioxide protection welding, the overall performance of this equipment is stable, the failure rate is low, one of the shortcomings is that the torch part of the MIG welding machine is vulnerable. Because the company uses the MIG welding machine supplied by Lincoln of the United States, it belongs to imported equipment and the spare parts are expensive (mainly referred to as welding torch). After Changan technicians research and years of practice, the welding torch spare parts of this welding machine have basically adopted domestic matching, which greatly saves the use cost and maintenance cost. Fixed nut projection welding machine - At present, the company mainly uses Nanjing Xiaoyuan equipment. The electrode nozzle of this equipment is made of ceramics, so it is very easy to be damaged. After the company technicians and suppliers jointly improve and improve, the electrode material is changed into copper. The overall performance of such welders is currently very stable.

There are two methods of robotic welding tongs control: servo control and pneumatic control. At present, the most used servo control tongs are used. The servo welding tongs have high requirements on the accuracy of the parts. If the accuracy of the parts is not up to standard, the failure rate of the robot servo welding tongs will be very high, and the maintenance cost is high, and the spare parts cost is also high, which is not conducive to the cost saving of the enterprise. The maintenance cost of the pneumatic welding tongs is relatively low, and the maintenance is convenient. The accuracy of the parts relative to the servo welding tongs has a low damage rate to the equipment.
Arc Welding Robots - The company currently uses two Japanese OTC brand robots. The arc welding performance is stable, easy to use and maintain, and it will not be analyzed in detail because there are too few applications.
â—†MIG welder 
Another disadvantage of the MIG welder is that the smoke and dust are relatively large during use. The company uses the equipment in the automotive welding production line. At the same time, it is equipped with the exhaust and dust removal equipment produced by the American Donaldson Company to ensure the operators on the production line. Occupational health and work environment are not polluted.
â—†Fixed nut projection welding machine, stud welding machine 
Stud welding machine - mainly manual and automatic, all imported from Germany EMHART. At present, the studs used for welding of this equipment are made in China, because the accuracy (consistency) of studs is relatively poor compared with imported products. Studs often cause automatic stud welding machine studs to stop, the main reason is that the automatic stud welding machine studs are caused by the stud size being oversized and the conveying system is stuck; the manual stud welding machine is relatively automatic snail The column welder is less affected by the accuracy of the stud and the overall failure rate is low. Due to the large investment in automatic stud welding machines, manual stud welding is suitable for the needs of the company from the perspective of long-term use.
Expectations for direct welding equipment categories:
With the advancement of society, labor costs continue to increase, robot prices are gradually reduced, and welding equipment will gradually become fully automated;
Laser welding methods will be widely applied to automotive welding production lines;
Low-energy, high-efficiency, non-toxic, non-polluting welding equipment will also be the technological advancement trend in the future automotive welding line.
