Electric resistance welding uses electrical current and pressure to join metals by generating heat through resistance. This method is highly efficient and is used in industries such as pipe welding, automotive and aerospace. This article explains its principles, types, and applications. Table of Contents What is Electric Resistance Welding? Electric resistance welding is a process […]

This is a detailed guide to the use of high frequency welding that will help you understand how HF welding equipment works in a welded pipe production line. Unlike other welding methods, High Frequency Welding (HFW) is a method of joining materials using electromagnetic energy (high frequency electromagnetic waves) to produce a strong, reliable weld,

Cold rolling vs hot rolling: two key steel processing techniques with distinct advantages. Cold rolling, done at room temperature, offers superior surface finish and precision. Hot rolling, performed at high temperatures, is more cost-effective. This article will explain their differences, benefits, and applications to help you choose the right process for your needs. Table of

Understanding the application of high strength steel pipe in new energy vehicles is key to appreciating their role in enhancing safety, efficiency, and performance. This article explores why these steel pipes are indispensable in components like battery systems, fuel systems, and chassis, and how they help meet the stringent demands of modern automotive engineering. Table

The difference between threaded pipe and welded pipe lies primarily in their connection methods. Threaded pipes use threads for easy assembly and disassembly, while welded pipes are fused for a strong, permanent bond. This article explores these methods, their strengths, applications, materials, installation, and costs to help you choose the right one for your project.

High frequency welding, or HF welding, is a process used to join thermoplastic materials using electromagnetic waves. This technique generates heat within the materials, causing them to melt and fuse. Unlike other methods that use external heat, HF welding heats the material internally through molecular friction. This article explores what is high frequency welding, how

Cold rolling steel is a process where steel is compressed at or near room temperature to increase its strength, improve its surface quality, and ensure tighter thickness tolerances. Unlike hot rolling, which uses high temperatures, cold rolling is done without heat, resulting in a harder and more precise material. This article will explain what cold

Many users want to understand the difference between ERW and EFW to determine which welding method is better for their projects. ERW (Electric Resistance Welding) joins steel plates using high-frequency electrical currents and pressure, making it efficient and clean. EFW (Electric Fusion Welding), on the other hand, uses consumable electrodes to melt the metal, creating

Carbon steel vs galvanized steel, what’s the difference? They are widely used in steel pipe production line or profile production line, how should we choose? In this article, we’ll break down the key differences between galvanized steel vs carbon steel to help you make an informed decision. Expect to learn about their properties, costs, and
