Brazing Processing Technology

2026-02-02

1. Core Mechanism Brazing is a metal joining process that uses a filler metal (braze alloy) with a melting point lower than that of the base metals but higher than 450℃. The process heats the assembly to a temperature where the braze alloy melts completely while the base metals remain in a solid state. Driven by capillary action, the molten braze alloy flows into the narrow gap between the faying surfaces of the base metals, then undergoes wetting and spreading to form a metallurgical bond with the base metals after cooling and solidification. 2. Key Pre-processing Steps - Surface Cleaning: Oxide films, grease, and contaminants on the base metal surfaces severely impair the wetting ability of molten braze alloy and capillary penetration. Mechanical cleaning methods include grinding, sandblasting, and wire brushing to remove surface oxides and roughness; chemical cleaning uses acidic or alkaline solutions to dissolve oxides and degrease, followed by thorough rinsing and drying to avoid residual corrosives. - Assembly and Gap Control: Joint clearance is a critical factor affecting brazing quality, typically controlled within the range of 0.02–0.2 mm. Too narrow a gap restricts capillary flow of the braze alloy, while too wide a gap fails to maintain sufficient capilla...

1. Core Technical Components of Automatic Welding Machines 1.1 Intelligent Welding Power Supply System The welding power supply serves as the energy core of automatic welding machines, adopting inverter technology and digital control algorithms to achieve precise regulation of welding current, voltage, and waveform. Key technical features include: - Inverter control: Converts 50/60 Hz alternating current into high-frequency alternating current (10–100 kHz) through IGBT or MOSFET modules, with electro-optical conversion efficiency exceeding 85%—30% higher than traditional thyristor power supplies. It enables rapid response to dynamic load changes, with current adjustment response time less than 1 ms. - Waveform customization: Supports multi-waveform output (constant current, constant voltage, pulsed DC, AC square wave) to adapt to different welding processes. For example, pulsed MIG welding waveforms reduce heat input for thin-walled aluminum alloy components, while high-frequency square wave waveforms enhance oxide film cleaning during aluminum TIG welding. - Energy management: Integrates load monitoring and energy feedback functions, automatically adjusting power output according to weld seam position and material thickness to minimize energy consumption...

What Materials Can Be Used For Laser Cutting

2026-01-23

To contextualize the suitability of materials for laser cutting, it is first critical to establish the technical fundamentals of the process. Laser cutting—an advanced thermal ablation technology employed in Computer Numerical Control (CNC) laser cutting systems—utilizes a coherent, monochromatic laser beam (focused via optical lenses to achieve energy densities of 10^6–10^8 W/cm²) to induce material transformation through melting, vaporization, or oxidative degradation. The efficacy of laser cutting is inherently dependent on the material’s optical properties (absorptivity at the laser wavelength), thermal characteristics (thermal conductivity, melting point, specific heat capacity), and chemical composition. Three primary laser types dominate industrial applications: fiber lasers (1064 nm wavelength, optimal for metals), CO₂ lasers (10.6 μm wavelength, ideal for non-metals), and Nd:YAG lasers (1064 nm, versatile for both metals and ceramics). The non-contact nature of the process minimizes mechanical stress, ensuring minimal material deformation, narrow kerf widths (0.1–0.5 mm for precision applications), and high dimensional accuracy (±0.01–±0.1 mm), making it indispensable across aerospace, automotive, electronics, and advanced manufac...
