Description

Technical Field

[0001] This utility model relates to the field of automobile longitudinal beam production technology, specifically to a welding equipment for automobile longitudinal beam production. Background Technology

[0002] The chassis is the most important load-bearing component in a car, and the longitudinal beams are one of the key parts within it. Therefore, longitudinal beams play a crucial role in the load-bearing capacity of a car, and both side-beam and center-beam chassis types contain longitudinal beams. Longitudinal beams are usually stamped from low-alloy steel sheets, and their cross-sectional shape is generally channel-shaped, although some are made into Z-shaped or box-shaped sections.

[0003] According to a patent application published on the Internet (authorization announcement number: CN219234370U), "This utility model relates to the field of component welding technology, and in particular to a welding device for automotive parts. The movable clamping frame enables the movement of parts, thereby enabling welding between parts of various lengths. The device allows the operator to place one part to be welded in the groove on the upper side of the part fixing plate, and another part to be welded in the groove on the upper surface of the right limiting frame and the movable clamping frame, eliminating the need for positioning between parts and making the device highly efficient. Due to the adjustable spacing design, this device can meet the welding needs of parts of various shapes and lengths. The welding slag produced will slide down into the welding slag collection box through the inclined design of the inclined side wall, thus eliminating the need for welding slag removal."

[0004] Based on the above, the applicant believes the following deficiencies exist:

[0005] This automotive parts welding device features an adjustable spacing design, enabling it to meet the welding needs of parts of various shapes and lengths. The welding slag produced is collected in a slag collection box by sliding down the inclined sidewall, eliminating the need for slag removal. However, during metal welding, the weld joint often comes into contact with a large amount of air. Prolonged exposure to air can cause the weld to oxidize due to oxygen, and dust may also enter the weld. All of these factors can affect the quality of the weld and the strength of the metal weld.
