Laser welding machines have a wide range of automotive applications (the role of laser spot welding machines)

Laser welding machines are used in a wide range of applications in the automotive industry. For example, laser welding machines are essential in a variety of applications such as engine intake manifold welding, automotive intake manifold orifice welding, crankshaft connection tube welding and automotive crankshaft connection piece welding. An example is the laser welding machine in both powertrain and engine housing. If there is an air mixture inside the engine, the laser welding machine is able to filter out these gases very well. Inside car bodies, where air is one of the main contaminants, laser welders must be used to exchange heat with heated parts in order to eliminate harmful gases and protect the components.

1. Automotive engine intake manifold orifice welding

Automotive engine intake manifold orifice welding is one of the key components of the engine. An example is the car starter generator system. When the engine is working, the air mixture and moisture escape from the air. At the same time, the presence of water inside the engine requires an air cooler to cool the air and expel it from the engine in time. In this case, the laser welding machine enables the protection and sealing of the gas between the engine intake manifold nozzles. This is because the gas must not only pass through the air cooler, but must also be treated by the laser before it can be used. If harmful gases are present, they can have a serious effect on the engine parts. It is therefore very important to protect the parts in the air.

2. Welding of sheet metal joints

The advantage of welding sheet metal joints is the good mechanical properties of the weld. Laser welding machines are characterised by high energy, low heat input, high welding speed and a small heat affected zone in the weld. Laser welding machines can also be used to weld between the seam and the plate in the automotive manufacturing process. The method is completed by processing the welded joint and welding it according to the design requirements of the welded structure. The method has high welding efficiency and good weld quality, which can greatly reduce the processing time and the disadvantages of poor quality.

3. Automotive crankshaft joint welding

In engine crankshaft joint welding, the welding current is used to exchange heat with the heating material to melt the welded joint. This method has a high efficiency. In engine operation, the power factor is 0.9 or less and the heating temperature is 200-600°C. By laser welding to the engine crankshaft, exhaust gases can be effectively eliminated or reduced where they pose a safety hazard to the inside of the engine cylinder and prevent situations such as ruptured piston rings, valve covers or exhaust pipes. In this process, when the laser beam in laser welding is in full contact with the heat input material of the welded part, the heat barely diffuses to the workpiece, allowing the heat input material to melt. The laser welding machine can also be heated or cooled at the same time as the surface of the welded workpiece, resulting in uniform and rapid heating and cooling of the workpiece surface. Over time, the laser welding machine gets better mechanical and thermal properties compared to welding equipment, making it a great alternative to manual processing in which high-cost parts have to be manually processed to produce new products, thus reducing production costs, increasing productivity and reducing scrap rates; it can also provide favourable conditions for the final delivery of good product quality or extended service life: the advantages are Laser welding is a simple, cost effective and efficient process that meets the requirements of a wide range of components.
