- Bata Interface Thermal Resistance Management
Quantified Influencing Factors: Surface roughness Ra ↑0.1μm inowedzera kupisa kwekushisa +8%; Oxide layer ukobvu ↑1μm inowedzera +15%; Kudzvanywa kwekubata ↓10% kunowedzera +12%.
III. Welding Process Parameter Settings
- Precise Energy Input Control
Maitiro Ekuisa Heat: Q=0.5 × C × V² × η (C=kugona, V=voltage, η{4}kugona).
Mienzaniso Inofananidzwa Copper-Nickel (60-80 J / mm², 15-20ms); Titanium-Stainless Simbi (85-110 J/mm², 25-30ms).
- Dynamic Pressure Adjustment Technology
Dzvinyiriro-Tembiricha Yekubatanidza Modhi: Kudzvanywa kwekutanga 800-1200N (inovimbisa kugadzikana kwekuramba); Bata kudzvanywa 400-600N (inokurudzira nugget solidification).

IV. Kutonhodza System Kubudirira
- Mvura Inotonhorera Circuit Heat Exchange Efficiency
Key Parameter Standards: Inotonhorera Inoyerera Mwero (6-8 L / min, ± 0.5 L / min kutsauka); Inlet/Outlet Temp Difference (<5°C); Conductivity (<50 μS/cm, +10μS/cm alarm).
Yambiro nyaya: Inotonhorera inosvibisa yakakonzera kudonha kwe60% mukutsinhana kwekushisa pafekitori yemudziyo, zvichikonzera kukwira kwetembiricha ye electrode uye spatter yewelding.
- Mhepo Inotonhorera System Optimization
Yakamanikidzwa Convection Dhizaini: Mhepo inomhanya ≥8m/s (inowedzera散热功率 ne55%); Deflector angle 15 ° ± 2 ° (inoderedza mhirizhonga 30%).
V. Material Thermophysical Properties
- Resistivity Difference Muripo
Matanho Akasiyana Ezvinhu: Mhangura-Aluminium (Resistivity ratio ~1:1.6, shandisa pre-mabhampa mabump structures); Simbi-Nickel (~1:5.2, shandisa kaviri-kupinza simba remhepo).
- Phase Shandura Latent Heat Management
Nugget Formation Thermodynamic Model: Hunoshanda kupisa Q_eff=Q_input - (Q_conduction + Q_phase), apo Q_phase chinhu chenyama chinochinja kupisa kwakadzikama.
Aerospace Dzidzira: Yakagadziridzwa iyoEnergy Storage Spot Welderpulse profile yetitanium alloy's β-phase shanduko maitiro (latent heat 650 J/g), kunatsa nugget saizi yezviyo kusvika 8μm.
VI. Environmental Factor Interference
