What is the application of orbital welding machines?

At present, the development of railways is mainly towards high-speed passenger cars, subway passenger cars, light rail cars, high-speed heavy trucks, etc. To meet these requirements, it is necessary to adjust the weight of the trains. Nowadays, it is common practice to use aluminum alloy materials in the manufacturing process of passenger cars. Because aluminum alloy materials have the characteristics of light weight, corrosion resistance, smooth appearance, complex curved surfaces and high specific strength, they can effectively reduce the resistance and quality of passenger cars. Increased overload. In order to effectively improve the processing efficiency of aluminum alloy materials, it is necessary to change the traditional processing method and use the welding technology of orbital welding machine for processing and manufacturing.

How is the orbital welding machine used?

(1) Welded parts preparation: Given the high hardness of rail steel, it is difficult to process the groove on site. Therefore, the orbital welding machine adopts the docking method and uses the existing end surface of the rail as the working surface. If the end face is heavily corroded, the angle grinder must be used to polish the surface bare.

(2) Determination of the impact gap: Given the height of the rail itself, the gap must not be too small, otherwise the welding wire for welding work cannot penetrate it, so it is necessary to reserve enough gap.

(3) Welding preheating: In the preheating process of orbital welding machine, a gas welding torch is used for preheating, and an infrared temperature measuring gun is used to ensure that the preheating reaches the specified temperature.

(4) Shock surface process: The entire welding process adopts the multi-layer multi-pass welding process. Although this process is relatively inefficient, it can ensure the weld strength and temperature between the layers.

(5) Heat treatment after welding: The heating process of the orbital welding machine uses a gas welding torch. After heating to the specified temperature, asbestos felt is used for heat preservation to prevent the appearance of cracks after welding.

(6) Grinding the workpiece after welding: The orbital welding machine keeps the weld seam and the base metal of the rail smooth.

What are the features of the orbital welding machine?

The biggest feature of orbital welding machine is small-scale local heating, high heating efficiency, easy operation, which is very suitable for fast heating and cooling of high manganese steel welding, and also suitable for welding repairs of local defects on rails. It is currently the most widely used method for welding rails and track grooves. Methods. However, it must be noted that the orbital welding machine for rail welding must be properly preheated. Due to local heating and rapid cooling of the rail, slightly abnormal brittle structures such as martensite and bainite can be generated, which increases the brittleness of the rail. Preheating prevents abnormal tissue formation.

Wincoo Engineering Co., Ltd strives to offer high quality products at reasonable prices, efficient production times and the most professional customer service.

The orbital welding machine uses the arc to burn between the electrode and the workpiece as a heat source to heat the electrode and the base metal. Under the action of the arc heat source, the molten electrode metal and the partially molten base metal form a molten pool, and the molten pool solidifies to form a weld.

How does an orbital welding machine work?

The orbital welding machine uses the heat energy generated by the combustion of the oxygen-acetylene flame to heat the ends of the butt-welded rails to a molten state, and then applies a certain upsetting pressure to weld the rail ends. There are two existing methods: factory welding and mobile welding. Factory welding is the same as contact welding. The mobile welding method, also known as small air pressure welding, is mainly used to weld the joint joints of the long rails on the construction site. The quality of air pressure welding is also better. Aluminothermic welding. Put the prepared aluminothermic flux (made of metal aluminum, iron oxide, iron alloy and iron nail head, etc.) into a special crucible, ignite the flux with a high-temperature match, and produce a strong chemical reduction reaction to obtain high-temperature molten steel and molten steel. Slag, after the reaction is calm, inject it into the preheated sand mold tightly fastened to the ends of the two rails, melt both ends of the butt joints, remove the sand mold after cooling, and reshape the welded joint in time. Welded into one. The quality of aluminothermic welding is poor, and the fatigue strength is even worse, only reaching 45% to 70% of the base metal.

What are the economic benefits of using an orbital welding machine?

(1) Orbital welding machine can run smoothly, safely and reliably.

(2) Orbital welding machine prolongs the service life of running vehicles and rails and reduces maintenance costs.

(3) Practice has proved that the running speed of vehicles running on seamless tracks can be increased by 20% to 40%, which can improve productivity for factories with busy vehicles and large distances, and its economic benefits are very obvious.

(4) The use of the orbital welding machine eliminates the vibration noise of the joint to a certain extent and improves the working environment. The drivers of the vehicles running on the seamless track generally report that the operation is smooth and comfortable. After testing, the driver's indoor noise has been reduced by more than 10dB, and the outdoor noise has been reduced by more than 35dB.
