Aluminum Alloy Car Body for MIG Welding 200EMU

1. Introduction

Lightness, high speed, safety, energy efficiency, comfort and long service life are the symbols of modern railway vehicles.

The key to achieving the train's speed is to solve the train's lightness and sealing problems. Lightness is essential for reducing energy consumption, reducing train traction and braking forces, reducing wheel-rail wear and increasing train circulation speed.

Sealing directly affects the train's operational performance and passenger comfort. The use of aluminum alloy materials is an effective measure to reduce the weight of the car body.

The 200EMU car body mainly uses three types of aluminum alloys: 5000 series, 6000 series and 7000 series.
