Description

Technical Field

[0001] This utility model relates to the field of welding operation technology for aluminum alloy car bodies of rail vehicles, and in particular to a mobile welding auxiliary device. Background Technology

[0002] The aluminum alloy body of rail vehicles involves a large amount of welding, with the longest weld exceeding 22 meters, and over 90% of the welds require manual welding. To facilitate welder operations and ensure welding quality, most body welds are located in PA and PC positions. Because of the relatively low position of these welds, welders must kneel or squat to observe the molten pool, resulting in high labor intensity and significant physical injury.

[0003] In actual welding operations, welders must kneel or squat to complete the welding process and joint grinding. Maintaining this kneeling or squatting posture for long periods every day causes the body's weight to be concentrated on the knees and lumbar spine. As a result, many welders suffer from knee injuries and herniated discs.

[0004] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a mobile welding auxiliary device. Utility Model Content
