PROCESSING TECHNOLOGY

--

• Material Selection: High-quality materials are selected for both the contact caps and the fuse bodies. These materials are chosen for their electrical conductivity, mechanical strength, and compatibility with the laser welding process.
• Stamping of Contact Caps: The process begins with stamping the contact caps from sheet metal. Stamping involves the precise cutting and shaping of the metal to form the contact caps' required geometry and features.
• Preparation of Fuse Bodies: The fuse bodies are prepared through machining or stamping processes, creating the appropriate shapes and dimensions to accommodate the contact caps.
• Contact Cap Placement: The stamped contact caps are positioned over the designated areas on the fuse bodies. Proper alignment is crucial for achieving accurate laser welds.
• Laser Welding Setup:

    a. Laser System Calibration: The laser welding system is calibrated to ensure accurate energy delivery and focus during the welding process.

    b. Laser Parameters Selection: Optimal laser parameters, including power, pulse duration, and beam intensity, are chosen based on the materials and joint geometry to achieve strong welds.

• Laser Welding Process:

    a. Energy Application: The laser beam is precisely directed onto the joint area where the contact cap and the fuse body meet.

    b. Fusion of Materials: The focused laser energy generates localized heat, causing the materials to melt and fuse together.

    c. Solidification: As the laser beam is moved along the joint, the melted materials solidify, creating a strong welded connection between the contact cap and the fuse body.

• Stamping Verification: After laser welding, the stamped contact caps' position and alignment are verified to ensure that they are correctly attached to the fuse bodies.
• Quality Control and Inspection:

   a. Visual Inspection: The welded joints are visually inspected for any defects, irregularities, or inconsistencies.

   b. Dimensional Verification: Precise measurements using calibrated tools are taken to ensure that the contact caps are aligned accurately and that the overall dimensions meet specifications.

   c. Weld Integrity Testing: Non-destructive tests such as ultrasonic testing or X-ray inspection may be conducted to assess the quality and integrity of the welds.

   d. Electrical Conductivity Testing: The electrical conductivity of the welded joint is measured to ensure optimal electrical performance.

• Surface Treatment: If necessary, surface treatments like plating or coating can be applied to enhance corrosion resistance and overall durability.
• Documentation and Records: Comprehensive records of the welding process, inspection results, and quality control steps are maintained for traceability and quality assurance.
