Product Introduction

Overview

Entry Section Strip End Welding Machine is an essential auxiliary welding unit for ERW tube mill lines. It is designed to continuously join the tail end of the active steel coil with the head end of the incoming coil during pipe production. The equipment enables non-stop operation of the ERW pipe mill, significantly cutting downtime, boosting production efficiency and reducing scrap rates for carbon steel, galvanized steel and alloy steel pipe fabrication.
Adopting an integrated shearing and welding design, our shear end welder automatically trims uneven steel strip ends, precisely aligns strip edges and finishes butt welding in a single cycle. Fitted with a reliable resistance welding system, it produces flat, strong and crack-free weld seams. The spliced steel strip can travel 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 offered to accommodate various strip widths and thicknesses for ERW steel pipe mills, supporting round tube and square tube manufacturing. Key features include hydraulic clamping, rapid strip end shearing, automatic edge alignment, user-friendly operation and low maintenance. Its heavy-duty rigid frame ensures a long service life under continuous high-load working conditions.
As core equipment for seamless coil joining in electric resistance welding tube mills, this shear end welder is well suited for steel pipe manufacturers producing ERW tubes, hollow sections, scaffolding tubes and structural pipes. It allows continuous strip feeding, eliminates frequent mill shutdowns for coil changes and maximizes the 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.
