Tube to tube sheet header box welding machine set is an automated welding system designed for heat exchangers, boilers and pressure vessels. This equipment set achieves high-quality connection between tubes and tube sheets through precision control, meeting the stringent standards of nuclear power, chemical and other industries.
Core components of tube to tube sheet welding machine set
1. Welding machine: Adopting servo drive system, positioning accuracy reaches ±0.02mm Equipped with dual pulse welding power supply (200-400A) Integrated visual centering system, automatic compensation of assembly deviation
2. Tube sheet positioning device: Hydraulic clamping mechanism (maximum clamping force 10 tons) 360° rotating worktable (load-bearing 5 tons) Adaptive to different tube sheet thicknesses (20-200mm)
3. Control system: 10-inch industrial touch screen Pre-store 50 sets of welding process parameters Real-time monitoring of welding current/voltage curve
Typical applications of tube to tube sheet welding machine set
1. Power industry: Boiler superheater tube sheet welding Nuclear power steam generator maintenance
3. Refrigeration equipment: Condenser tube sheet assembly Evaporator unit welding
Purchase suggestions
1. Selection points: Select welding head specifications according to the tube diameter (Φ10-80mm) Confirm the matching of tube sheet material (carbon steel/stainless steel/nickel-based alloy) Evaluate the workshop space (equipment covers an area of ??about 6×4m)
2. Cost analysis: European and American equipment: 400,000-700,000 yuan Chinese equipment: 120,000-400,000 yuan Investment payback period: usually 1.5-3 years
3. Supplier evaluation: Require customer cases Confirm service capabilities Prefer manufacturers that provide trial welding services
The header box tube to tube sheet welding set combines flexibility and reliability through modular design, which is particularly suitable for mass production scenarios. It is recommended to arrange on-site trial welding before purchasing, focusing on verifying the forming consistency of welds in different positions.
