Description

technical field

[0001] The invention belongs to a welding machine, and particularly designs an automatic circular welding machine for excavator arm and loader rocker arm. Background technique

[0002] Both the excavator arm and the loader rocker arm are of circular structure, which requires uniform welding, good quality, and good appearance. The original production is manual welding, the quality cannot be guaranteed, and the uniformity and appearance are not ideal. Low efficiency and high labor intensity. With the advancement of science and technology, there have been a variety of welding machines, which have complex structures and high costs, and are especially unsuitable for welding the circumference of parts of large-scale machinery such as excavator arms and loader rocker arms with a diameter of 200 to 2000 mm. Contents of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, and provide a welding machin...
