I. Truck Axles: Characteristics and Advantages

In the realm of truck dynamics—engines, gearboxes, and axles—the latter serves as the linchpin, facilitating the transfer of power and playing a pivotal role in ensuring the vehicle's stability and overall power transmission.

Functionally connecting suspension to the chassis while hosting truck wheels at either end, axles serve to transmit directional forces and torque between the chassis and wheels. They are broadly categorized as integral or detachable structures. Integral axles, resembling colossal barbells, are supported by the suspension system at both ends, often in conjunction with non-independent suspensions. On the other hand, detachable axles are akin to twin umbrellas attached to each side of the vehicle, individually supported by the suspension system, and typically used with independent suspensions.

Segmented by driving mechanisms, axles branch into four types: steering, driving, steering-drive, and support axles, with steering and support axles classified as non-driving axles. Most trucks adopt front-engine rear-wheel drive (FR), utilizing the front axle for steering and the rear for propulsion. In contrast, front-engine front-wheel drive (FF) trucks utilize the front axle for both steering and propulsion, with the rear axle serving as support.

III. Challenges at Axle Welding Sites

Constructing axles primarily involves welding several parts—semi-axle casings, fixed plates, rear covers, flanges, and semi-shaft sleeves. The welding process involves overlapping welds for reinforcement rings, rear covers, and axle casings. Employing positioners to rotate axle casings, the angle set at 45 degrees, with the welding torch held vertically, synchronized with dedicated machinery for welding. The specifications entail flawless weld seams, minimal spatter, complete fusion, and a fusion depth exceeding 1mm, culminating in impeccable, leak-free, and aesthetically appealing welds.
