KHYB Circumferential Seam Welder for Prefabricated Pipe

The KHYB circumferential seam welder is a high-precision automatic welding machine designed specifically for circumferential seam welding of prefabricated pipes, suitable for pipes with an outer diameter of 50mm or greater. Equipped with a highly stable roller positioner, an adjustable pipe centering bracket, and a high-response welding actuator, the machine ensures consistent weld formation and high welding accuracy. The KHYB circumferential seam welder utilizes advanced PLC control technology and can store up to 100 welding programs, each of which can be divided into 1 to 12 sections, enabling intelligent control of multi-layer and multi-pass welding parameters.

Application:

The KHYB circumferential seam welder is widely used in petrochemical pipelines, boiler and pressure vessels, and food and pharmaceutical equipment manufacturing. It is particularly suitable for automatic circumferential seam welding of stainless steel, carbon steel, and alloy steel pipes.

Advantage

1. PLC control system, can store up to 100 groups welding programs, each group of welding program can be divided into 1-12 paragraphs. The operating interface uses the LCD10.1 touch screen, easy to setting the programs.

2. Adopting OTC brand DT300PⅡmodel DC inverter pulse power source, high welding efficiency, stable arc, finished welding effects will be beautiful and strong.

3. Water cooling system, ensure the machine can keep working with long time.

4. The trolley type designing, easy to move.

5. Water, electric, gas connect joints are connected conveniently, the machine has engine start function.

Structure

a) Equipment structure:
The equipment includes roller positioners, pipe centering support, welding actuator, welding system, and control system.

b) Operating Principle:
Cleaning the pipe end, beveling the pipe end with standard technology, ensure the unfitness of pipe butt joint is no more than 1mm, and it needs spot welding firstly.
