Track Transportation is an important part of urban transportation, which has long appeared in cities and plays an increasingly important role. It is an effective way to improve the urban public transportation condition fundamentally. The high speed of trains, on the one hand, requires improving the traction power of locomotives, on the other hand, it requires realizing the lightweight of the trains and adopting the external design with less resistance. The effective solution is one of the most important key technologies for the development of high-speed trains.

Metal dynamic composite provides superior connection performance and is the only high strength heterologous metal welding solution widely used in industry. The metal clad materials produced by Gallianz can be made into metal clad plates, clad tube sheets, clad pipes, head and other forms according to the applications, which have good mechanical properties, strong fatigue resistance and corrosion resistance. These clad materials can extend the effective life of the manufactured ships and vehicles.

In order to reduce the weight of the car body and improve the carrying capacity, the car part of the high-speed will be made of aluminum alloy structure. The aluminum steel joint produced can realize the direct welding between the upper stainless steel sheet metal and the lower steel structure of the high-speed train. Compared with the traditional screw connection, it has the characteristics of high connection strength, strong corrosion resistance and easy installation. Gallianz can manufacture the aluminum steel clad plates for your track transportation components use. In order to realize the sensitive induction under the stability, Gallianz produces the copper steel clad plate and aluminum clad steel plate for the induction board. These two clad materials are metallurgically bonded, which are with good electrical conductivity, and high strength, lower thickness, and greatly lower-cost.

There are many stainless steel sheet manufacturers, but we are the best choice for you.

Welding processes

Gallianz is noted for its long-standing experience in welding special clad materials. Improving welding processes is considered as a core task of our welding technology. We have some advanced innovation patents of welding actually, meanwhile, we have been developing welding technologies and testing with samples all the time. We deeply know that welding is one of key processes.

At Gallianz, submerged arc welding (SAW), electrogas welding (EGW) and Gas metal arc welding (GMAW) are used professionally during the whole manufacturing processes. It is ultimately the customer's specification which prescribes the welding processes to be applied. There are many experienced welders and latest welding machines to make sure the cladding welding quality and process improvements in efficiency at the factory.

Basic knowledge of welding:

1. Welding method: there are three elements: accurately clean, heating and welding, which is the most basic and the most important condition of electricity. If one of three elements is not full and accurate implementation, it will cause poor welding, become a hidden danger of failure.

2. Three elements of clad pipe welding:

Cleaning: clean metal surface, clean welding equipment, clean welding accessories equipment;

Heating: the contact method of the iron head;

Welding: the amount of solder, the evacuation method of the iron head, the difficulty of welding;

3. Rosin features: cleaning, insulation, welding

4. Rosin function:

Remove oxide

Prevent oxidation during the welding process

Reduce the surface tension of the solder (outward expansion

copper clad aluminum have good electrical and thermal conductivity, and they are the basic materials in power transmission and heat transfer engineering. A layer of copper is cladding directly on the aluminum surface, the copper-aluminum clad material can improve the contact resistance of the aluminum surface, and improve the welding performance of aluminum, with the advantages of low price and light weight. It is many important parts of heat exchanger, power transmission and electrical equipment, such as heat sink, heat collector pipe, transition board, etc.

The aluminum steel explosive welding material and the aluminum titanium steel explosive welding block are mainly used in the cathode, anode materials, transition joint, for connecting the steel claw and aluminum guide rod. They solve the problem of heterogeneous metal connection, small resistance, good conductivity, while they are saving energy consumption, enhancing the life of the equipment.

In the metallurgical industry, copper clad steel plate materials are used as the electrode for electroplating and electrolysis technology, discharge processing electrode, grounding rod, conductive transverse arm body, electrode clamp head, electrode clamping and relaxation mechanism, etc. Bimetallic bearings, and linings can be manufactured with copper-steel and aluminum-steel clad materials. Make double water cooling shell and double crystallization of electrometallurgical furnace and melting furnace by copper-steel clad plates.

There are many clad plate suppliers, but we are the best choice for you.
