First, copper and steel pipe welding principle
Copper and steel pipe are both common metal materials, they have different chemical and physical properties, so they need to use different processes and methods when welding.
The melting point of copper pipe is lower than that of steel pipe, and welding requires the use of high temperature flame, such as oxyacetylene welding. The melting point of steel pipe is higher than that of copper pipe, which requires the use of high energy arc, such as arc welding.
In the welding of copper and steel pipe, because the chemical and physical properties of the two are different, so it is difficult to achieve direct welding, you need to first intervene through the copper alloy material to achieve the two joints.
Second, the copper and steel pipe can be welded together
Because the chemical and physical properties of copper and steel pipe are different, it is difficult to realize the direct welding, usually need to use intermediate materials to join.
Through the intervention of alloy materials to realize the welding of copper and steel pipe. The choice of alloy materials is more flexible and can be selected according to the specific situation, but it is necessary to ensure the robustness and corrosion resistance of the joint.
Therefore, copper pipe and steel pipe can be welded together by alloy materials, but need to choose suitable intermediate materials to realize. Theoretically, as long as you choose the right material, choose a good process, any metal can be welded together.
Third, copper and steel pipe welding method
- Before welding, use sandpaper, mop and other cleaning tools to remove grease and dirt from the surface of the copper and steel pipe in order to weld better adhesion.
- Copper and steel pipe should be selected before welding suitable welding materials to ensure the welding quality of the joints as well as corrosion resistance.
- Suitable tools and process should be used when welding to avoid too high or too low temperature, which may lead to poor welding quality or cause problems such as melting at the joints.
- After welding, the joints of copper and steel pipes should be wiped with clean cloth or paper towel, and the appearance should be checked and tested to ensure that the welding quality meets the requirements.
[Conclusion
Through the intervention of alloy materials, the welding of copper pipe and steel pipe can be realized, but it is necessary to choose suitable intermediate materials to realize it, and pay attention to the welding process and method to ensure the welding quality.
