ERW pipe terminology analysis: Understand commonly used ERW pipe related terms

1. What is ERW tube?

ERW pipe, the full name of Electric Resistance Welded Pipe, is a seamless steel pipe that uses high-frequency current to preheat through the edges and connect steel plates to form a pipe. It has the advantages of high production efficiency and stable quality, and is widely used in many fields.

2. Common ERW pipe terms
2.1 Electric Resistance Welding
Resistance welding works by applying resistance to a heated area to heat the edges, and then using pressure to join the two edges to form a pipe. This welding method is suitable for thinner wall pipes.

2.2 High Frequency Induction Heating
High-frequency induction heating uses high-frequency current to generate eddy current heat inside the steel pipe to heat the steel pipe to the welding temperature. This heating method is fast and even, ensuring welding quality.

2.3 Welding Coil
Welding coils are coils used to generate high-frequency electromagnetic fields, which convert electrical energy into thermal energy and are used to heat the edges of steel pipes.

2.4 Weld
The weld refers to the connection formed by the ERW pipe during the welding process. It is formed by the fusion of two heated edges under the action of high-frequency current and pressure.

2.5 Fusion Zone
The fusion zone refers to the area that is heated to a molten state during the welding process. It is formed by the fusion of two edges, and the quality of the welding depends on the formation of the fusion zone.

2.6 Non-Fusion Zone
The non-fusion zone refers to the area that is not completely fused during the welding process. This area may be affected by some external factors (such as welding speed, temperature, etc.), resulting in changes in welding quality.

2.7 Weld Strength
Welding strength refers to the strength index of the welded joint, which depends on the quality of the weld and the properties of the material.

2.8 Weld Quality Testing
Welding quality inspection is the process of inspecting and evaluating welded joints. Common testing methods include ultrasonic testing, X-ray testing, etc. to ensure that the welding quality meets standard requirements.

3. The importance of ERW terminology
Understanding and mastering common ERW management terminology is very important for those engaged in related industries. It can help us gain a deeper understanding of the production process, quality assessment and application scope of ERW pipes, thereby improving work efficiency and accuracy. At the same time, during the procurement and use process, being familiar with these terms can also help us choose appropriate products and communicate effectively with suppliers.
