What is ERW Tube Welding Machine

In modern industrial manufacturing, the ERW Tube Welding Machine is a crucial piece of equipment on steel pipe production lines, helping companies achieve efficient and stable steel pipe production. ERW stands for Electric Resistance Welding, which uses high-frequency welding to form steel strips into pipes with strong welded seams. This process is the mainstream technology for welded steel pipe production today.

Working Principle

The ERW tube welding machine can produce round and square pipes ranging from small to medium-large diameters. It features a compact structure and easy operation, meeting the diverse needs of various industries. Its core process is high-frequency resistance welding:

Steel strips pass through uncoiling, straightening, and forming to create a pipe blank;

The pipe blank generates resistance heat along the seam in the high-frequency welder, heating the steel to a molten state;

The weld seam is pressed and formed to create a strong joint;

Finally, the pipe is cooled, straightened, and cut to produce the finished product.

This process is highly efficient, produces strong welds, and ensures consistent dimensional accuracy, making it the mainstream method for welded steel pipe manufacturing.
