Welding Essentials for Cars and Cargo Vehicles

The automotive engine, gearbox, axle, frame, body and comppartment are six major assemblies of cars, which are inseparable from the application of welding technology. The following section introduces common automobiles - cars and cargo vehicles welding points.

I. Car welding

1. Cars are designed to carry people, so they require high safety and ride comfort.

2. Common welding structures on cars include spot welding structures, arc welding structures, projection welding structures, bolt welding structures, laser welding structures, etc.

3. The most common welding process used in cars is spot welding, and there are about 3,000-6,000 welding spots on one car.

4. Generally speaking, increasing the number of spot welds and decreasing the length of arc welds is one of the basic ways to improve the quality of body buildin.

II. Cargo vehicles

1. Cargo vehicles are designed to carry and transport goods, so they require high load-carrying performance and safety.

2. Common welding structures on cargo vehicles include spot welding structures, arc welding structures, projection welding structures, and bolt welding structures.

3. Unlike cars, arc welding structures are most commonly used on cargo vehicles.
