Automatic U-Type Stainless Steel Orbital Pipe Welder for Heat Exchanger Tube. Specialized U-Tube Welding: Engineered for heat exchanger U-tube fabrication, handling tight radii and variable access challenges. Compact Low-Profile Design: Compact weld head navigates congested tube sheets of shell-and-tube heat exchangers easily. High-Quality Weld Finish: Minimal heat-affected zone and zero spatter ensure uniform, beautiful, and clean weld beads. Optional Integrated Wire Feeder: Supports optional cold/hot wire feeding for smooth filler deposition on thicker wall sections. Water Cooling System: Equipped with torch water cooling to maintain performance during continuous orbital welding operations. Reduced Rework & Extended Life: Eliminates manual TIG inconsistencies, dramatically reducing rework and extending heat exchanger service life.
