FAQ
Q1: How can I produce high-precision stainless steel heat exchanger tubes?
A1: High-precision heat exchanger tubes require accurate strip thickness, forming, welding, sizing, and annealing control, combined with reliable inspection. Hangao provides heat exchanger tube production lines integrating welding, sizing, annealing, and inspection systems.
Q2: How can I improve weld consistency in stainless steel tube production?
A2: Weld consistency depends on strip-edge condition, forming accuracy, welding current, heat input, travel speed, shielding gas, and torch alignment. Hangao's three-cathode TIG system uses sequential edge cleaning, preheating, and deep welding with electromagnetic control to improve welding stability.
Q3：Why do stainless steel tubes have uneven weld beads?
A3: Uneven weld beads can result from poor strip-edge preparation, unstable forming, welding-current fluctuations, travel-speed variation, insufficient shielding gas, or torch misalignment. The problem should be investigated across forming, welding, and process-control systems rather than adjusting welding current alone.
Q4: How can I reduce undercut defects in stainless steel tube welding?
A4: Undercut can be reduced by controlling welding current, travel speed, strip-edge gap, torch angle, and shielding gas while keeping the strip edges clean. Hangao's three-cathode TIG system uses the first torch for edge cleaning followed by preheating and deep welding, helping reduce common defects such as undercut.
Q5: How can heat input be controlled during stainless steel tube welding?
A5: Heat input can be controlled through welding current, voltage, travel speed, laser power, and multi-stage welding strategies. For precision thin-wall tubes, optimized heat input helps reduce the heat-affected zone and deformation risk.
