Why does winter welding cause the clean pipe to change color and deform

I. Why does winter welding cause the deformation of the clean pipe?

During winter, the low temperature leads to uneven heating of the clean pipe, which easily causes deformation. Additionally, during winter welding, the temperature difference between the ambient air and the high temperature of the welding flame is significant. Therefore, a longer welding time is required during winter welding to ensure more uniform heating of the clean pipe, thereby reducing the risk of deformation.

If the clean pipe deforms, it will cause unpredictable damage to the installation and normal use of the pipeline. Therefore, when welding the clean pipe, it is necessary to operate under the premise of fully considering this issue and take corresponding preventive measures to prevent deformation from occurring.

II. Why does winter welding cause the clean pipe to change color?

The high temperature generated during winter welding is the main reason for the color change of the clean pipe. Due to the different materials used in the manufacturing of the clean pipe, it is prone to change color under high temperature. Therefore, during winter welding of the clean pipe, the temperature of the welding flame must be controlled, and an appropriate welding temperature should be maintained. In addition, during the welding process, attention should be paid to the cleaning and protection of the pipeline surface to prevent surface contamination and material changes.

The color change of the clean pipe not only affects the appearance of the pipeline but may also have adverse effects on the material flow inside the pipeline. Therefore, when welding the clean pipe in winter, the welding temperature must be strictly controlled to avoid the occurrence of color change, thus ensuring the safe and stable operation of the pipeline.

III. How to prevent the color change and deformation of the clean pipe during winter welding?

1. Control the temperature of the welding flame. During winter welding of the clean pipe, a longer welding time should be selected to ensure more uniform heating of the pipeline. While controlling the welding temperature, avoid drastic temperature changes that may cause deformation of the pipeline.

2. Maintain the cleanliness and protection of the pipeline surface. During the welding process, it is necessary to insist on cleaning and protecting the pipeline surface to avoid surface contamination and material changes.

3. Adopt corresponding pipeline fixation devices. During the welding process, pipeline fixation devices can be used to ensure that the pipeline does not deform or change color under high temperature.

In summary, the clean pipe is prone to color change and deformation during winter welding. Therefore, when operating, it is necessary to control the temperature of the welding flame, maintain the cleanliness and protection of the pipeline surface, and adopt corresponding pipeline fixation devices to prevent the clean pipe from undergoing adverse changes, ensuring the safe and stable operation of the pipeline.
