Overview
Our Steel Strip End Welder is an essential auxiliary welding unit for ERW tube mill lines. It is engineered to continuously splice the tail end of the running steel coil to the head end of the next incoming coil during pipe production. This equipment maintains non-stop operation of the ERW pipe mill, greatly cutting downtime, improving production efficiency and lowering scrap rates for carbon steel, galvanized steel and alloy steel pipe fabrication.
Featuring an integrated shearing and welding design, our strip end welder automatically trims irregular steel strip ends, precisely aligns strip edges and completes butt welding within one working cycle. Equipped with a dependable resistance welding system, it generates flat, robust and crack-free weld seams. The spliced steel strip can pass smoothly through the forming stands, sizing stands and high-frequency welding unit of the ERW tube production line without strip breakage during continuous pipe forming.
Custom configurations are available to suit a wide range of strip widths and thicknesses for ERW steel pipe mills, supporting both round tube and square tube manufacturing. Key highlights include hydraulic clamping, fast strip end shearing, automatic edge alignment, intuitive operation and low maintenance requirements. Its heavy-duty rigid frame promises a long service life under sustained high-load operating conditions.
As the core equipment for seamless coil connection in electric resistance welding tube mills, this strip end welder is ideal for steel pipe manufacturers producing ERW tubes, hollow sections, scaffolding tubes and structural pipes. It enables continuous strip feeding, removes frequent mill shutdowns caused by coil change and maximizes throughput of your ERW tube making machine.

Our Advantages
- Spiral weld seams are formed via angular shearing, delivering superior structural strength while effectively protecting the tube mill.
- Consistent welding speed ensures full wire penetration and excellent weld quality. The equipment also features simple operation and low maintenance requirements.
- Integrated automatic shearing, seam alignment and welding functions greatly boost overall production efficiency.
- An optional dual welding gun configuration is available for automatic CO₂ gas-shielded welding. It enables faster welding with higher current density, creating robust and reliable weld seams.
