In heat exchangers, header pipe systems refer to the piping network used to distribute cooling water or heating medium to individual heat exchange tube bundles. The cooling/heating medium enters the heat exchanger through the main pipeline, is distributed via branch pipelines to each tube bundle for heat exchange, and then exits the heat exchanger through the header pipes.
Pipe welding in heat exchangers is a critical manufacturing process. High-quality welding ensures hermetic sealing, strengthens structural integrity, guarantees safety, extends product lifespan, and reduces accident risks.
In actual production, heat exchanger pipe welding processes receive extensive attention. Through strict welding management, defect-free and high-quality outputs are ensured during mass production, improving both product appearance and internal quality. As specialized industry equipment, header pipe welders provide low-cost, high-quality welding solutions with broad applications.
Unlike common horizontal U-tube configurations, heat exchanger header pipes require vertical welding at unique angles unsuitable for standard equipment. Mwelding's R&D team developed the MWH-16AJSG header pipe welder to address this challenge.
Compact and lightweight for single-hand operation, this equipment uses argon arc autogenous welding (no filler wire) to achieve excellent stainless steel socket welds with smooth bead formation. Continuous operation reduces waiting time, improving first-pass合格率 and shortening project duration. The integrated clamping system, automatic controls, and expert parameter support enhance usability, allowing unskilled operators to produce high-quality welds after minimal training—ideal for lean manufacturing and cost reduction.
The automatic welding control system includes an expert parameter database. Simply input tube diameter and wall thickness to generate optimized welding parameters, simplifying operation for beginners and accelerating process optimization.
Featuring a compact modular design, this U-tube welder accesses dense tube bundles with ease. Full digital control ensures high-quality welds, while intuitive button operation enables quick mastery by non-specialists. Parameter recording supports production management without relying on skilled welders.
Mwelding's proprietary U-tube welders (MWH series) are custom-engineered for heat exchanger applications using argon arc autogenous welding. They deliver reliable, pressure-resistant welds that enhance product quality and competitiveness.
Constructed with imported components, these lightweight welders offer precision, durability, and safety. Full-body water cooling extends duty cycle for continuous operation. Easy to operate, even unskilled workers can manage two machines simultaneously after training, reducing labor costs. Multi-gas protection ensures weld quality meeting HVAC industry standards. Customizable solutions available with full technical support, serving heat exchanger, refrigeration, aerospace, and instrumentation sectors.
