First, replace the girder: in the process of replacement, we should pay attention to matching our own models. Although the replacement cost is high, life is priceless.

2. Reset: The welding process should be carried out directly at the broken or bent part of the beam, but the stains on the broken part should be cleaned up in advance to prevent more serious damage after repair.

Causes of automobile girder fracture;

1. material: the automobile cross beam will break due to unqualified material, and the treatment of this reason can only start from the root cause.

2. Overloading and speeding: This reason often happens. Some drivers are overloaded and speeding regardless of their own lives.

The longitudinal beams for extending data are usually stamped from low alloy steel plates, and the cross section is generally trough-shaped, and some are made into Z-shaped or box-shaped. According to the different automobile forms and the requirements of structural arrangement, the longitudinal beam can be bent in the horizontal plane or the longitudinal plane, and the cross section can be equal or unequal.

The cross beam is not only used to ensure the torsional rigidity of the frame and bear the longitudinal load, but also to support the main parts of the car. Usually trucks have 5-6 beams, sometimes more. The structural feature of side beam frame is that it is convenient to install cab, carriage, some special equipment and arrange other assemblies, which is conducive to refitting variant cars and developing various models, so it is widely used in trucks and most special vehicles.
