Product Introduction

Overview

Our Hydraulic Steel Strip Butt Welding Equipment serves as an essential auxiliary welding unit for ERW tube mill lines. It is engineered to continuously splice the tail end of the active steel coil to the head end of the subsequent incoming coil during pipe manufacturing. This equipment sustains non-stop operation of the ERW pipe mill, substantially reducing downtime, lifting production efficiency and cutting scrap rates for carbon steel, galvanized steel and alloy steel pipe fabrication.
Adopting 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 a single working cycle. Fitted with a reliable resistance welding system, it produces flat, robust and crack-free weld seams. The spliced steel strip can travel smoothly through forming stands, sizing stands and the high-frequency welding unit of the ERW tube production line, with zero strip breakage during continuous pipe forming.
Custom configurations are offered to accommodate a broad range of strip widths and thicknesses for ERW steel pipe mills, supporting production of both round tubes and square tubes. Key features include hydraulic clamping, rapid strip end shearing, automatic edge alignment, user-friendly operation and low maintenance. Its heavy-duty rigid frame guarantees extended service life under continuous high-load working conditions.
As core equipment for seamless coil joining in electric resistance welding tube mills, this strip end welder is perfect for steel pipe manufacturers producing ERW tubes, hollow sections, scaffolding tubes and structural pipes. It enables continuous strip feeding, eliminates frequent mill shutdowns during coil changeover and maximizes throughput for 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.
