Design Of Welded Joints
Products Description
In the electrical and industrial equipment sectors, the Design of Welded Joints directly determines the stability, conductivity, and service life of metal components. With nearly 35 years of expertise in electric metal solutions, Apollo service focuses on conductive materials like copper and brass. Through customized structural planning and process adaptation, we deliver connection schemes tailored to real-world operating conditions. From small joints for electrical terminals to heavy-duty joints for industrial structural parts, our Fuse Contact Knife Cap adheres to international welding standards while adjusting details to fit clients' specific application scenarios, ensuring every weld balances strength, precision, and material compatibility.
Core Capabilities
Material-Adaptive Design
The End Cap and Contact at Apollo prioritizes compatibility with materials like copper (oxygen-free copper, phosphorus-deoxidized copper) and brass. For copper, we optimize joint configurations by adjusting groove gaps to reduce heat input, preventing material embrittlement. For brass, we align process parameters to minimize zinc evaporation, preserving the alloy's inherent properties. Additionally, our supports both homogeneous (copper-to-copper) and heterogeneous (copper-to-brass) connections, balancing mechanical performance and electrical conductivity for each material combination.
Scenario-Specific Joint Form Customization
Our Welding Joints for Fuse covers 5 primary joint types: butt, lap, corner, T-joint, and edge joints. We select the optimal form based on clients' load types (tensile, bending, shear): for example, lap joints are used for electrical terminals to maximize conductive area, while T-joint corner configurations enhance torsion resistance for heavy-duty structural parts. For extreme conditions (high temperature, vibration, corrosion), includes reinforced structures-such as sealed joints for corrosive environments-to reduce weld exposure to harmful media.
Synergistic Optimization of Process and Design
The Fuse Cap and Contact Resistance Brazing integrates TIG and MIG welding process characteristics into groove and joint design. For thin-walled copper parts (TIG-welded), we use small grooves and narrow gaps to minimize welding deformation. For thick components (MIG-welded), we design multi-layer, multi-pass joint structures. Beyond welding, also accounts for post-processing and assembly needs-for instance, reserving positioning datums on joint edges to simplify clients' component installation workflows.
Application Fields
| Electrical Industry | In the electrical sector, our Outer Cap and Terminal Welding Components supports copper busbar connections for high-low voltage switchgear, ensuring joint conductivity reaches over 90% of the base material while meeting thermal stability requirements under short-circuit currents. For wiring terminals, thesmall joints to fit the limited installation space of terminals, maintaining reliable electrical contact between terminals and wires. |
| Industrial Equipment Sector | For industrial fluid pipelines, the Fuse Cap and Contact High Temperature Soldering for copper pipes balances sealing and pressure resistance, matching the working pressure demands of hydraulic and cooling systems. In structural components, enhances the overall rigidity of copper alloy brackets and connectors in industrial machinery, supporting heavy operational loads. |
| New Energy Sector | In energy storage equipment, the Copper Cap and L-Type Termial for copper busbars in battery modules optimizes heat dissipation area to handle the thermal demands of high-current operation. For photovoltaic components, copper-based junction boxes ensures weather resistance, adapting to long-term outdoor exposure. |
Our Service Process
Requirement Alignment Phase
In the initial stage, we sync with clients' engineering teams to clarify core requirements: application scenarios, load parameters, material types, and installation space constraints. We also provide preliminary technical recommendations-for example, suggesting corner joints with reinforcing plates for high-vibration conditions to improve fatigue resistance in the Copper End Caps and Fuse Contact.
Design and Validation Phase
We deliver initial Fuse Contact Knife Cap proposals, including 2D/3D drawings of joint forms, groove dimensions, and fillet parameters, with key specifications (e.g., weld strength, conductivity) clearly marked. We then produce 1-2 sets of free samples, assisting clients in testing mechanical properties (tensile, impact) and electrical conductivity to validate the End Cap and Contact.
Mass Production and Delivery Phase
Based on sample test results, we refine the Welding Joints for Fuse (e.g., adjusting groove angles to boost welding efficiency). We complete mass production within 7-15 days and provide quality inspection reports (including non-destructive weld testing records) alongside the final Design of Welded Joints components.
