NISSAN Cabstar 3.3L ED33 1983-1990

This product, as one of the company's oldest product lines, has always provided stable and reliable services for the NISSAN ED33 engine.

We will talk about two main welding methods currently used in the industry.

Resistance welding: This is a method of welding that applies pressure through electrodes and utilizes the resistance heat generated by the current passing through the contact surface and adjacent areas of the joint after the welding components are assembled. Resistance welding has been widely used in industrial production due to its high efficiency and simplicity. However, due to the high temperature generated by resistance welding through high current, it is easy to cause minor cracks, deformation, and virtual soldering problems in the armature commutator, which affects the quality stability of the armature,

Argon arc welding: Argon arc welding uses inert gas argon as the shielding gas, effectively avoiding damage caused by high temperature and high pressure, and also solving problems such as virtual welding. Meanwhile, argon arc welding can also make the armature more stable during use, improving the overall performance of the product. However, the processing speed of argon arc welding is relatively slow, which to some extent affects production efficiency.

With the continuous progress of technology, we have not stopped at argon arc welding. In 2023, we began to study ion welding and laser welding methods again. Ion welding, with its high energy density and low heat input, can reduce the heat affected zone, reduce deformation risks, and improve welding quality during the welding process. Laser welding, with its advantages of high speed, high precision, and low heat input, has brought revolutionary changes to the welding industry. Although these two new technologies still face some challenges in application, such as equipment cost and process stability, we believe that with the continuous maturity and optimization of technology, they will become the mainstream way of armature welding in the future.

From resistance welding to argon arc welding, to ion welding and laser welding, the armature welding method of this product is constantly upgraded and improved, aiming to improve product quality and stability, and meet the constantly changing market demand. We firmly believe that through continuous technological innovation and process optimization, we will provide higher quality and efficient products.
