The HAIFEI automatic copper braid welding and processing line is developed for manufacturers producing copper braid shunts, flexible copper connectors and current-carrying components in repeat batches.
Starting with copper braid supplied in rolls, the line can be configured to complete material feeding, length positioning, clamping, resistance heating, end compacting, cutting and finished-part unloading. Additional punching, terminal welding, inspection or assembly stations can be integrated when required by the finished product.
Unlike a standard machine selected only by conductor cross-section, each copper braid welding line is configured according to the braid structure, compacted-end dimensions, finished length, production volume and downstream process. Drawings and material samples are therefore reviewed before the machine configuration and quotation are confirmed.

What Does the Automatic Copper Braid Welding Line Do?
Copper braid is flexible and can easily twist, spread or move during feeding and cutting. If the loose braid is cut directly, individual copper strands may separate at the edge, making subsequent positioning, punching and terminal assembly more difficult.
The automatic copper braid welding and processing line controls the material before cutting. Depending on the selected configuration, the production process can include:
- Feeding copper braid from a material roll;
- Guiding and aligning the braid;
- Positioning the material to the programmed length;
- Clamping the braid in a dedicated welding tool;
- Applying controlled resistance heat and pressure;
- Compacting the required section of the braid;
- Cutting the product to the programmed length;
- Unloading or transferring the finished component;
- Connecting the part to a subsequent punching, inspection or assembly station.
The required stations are selected according to the product. A customer manufacturing cut-to-length copper braid shunts may only need feeding, compacting, cutting and unloading. A switchgear component manufacturer may require additional punching, contact welding, terminal joining or dimensional inspection.
This modular structure allows HAIFEI to develop the automation around the actual production process instead of adding unnecessary functions to the machine.
A typical braided copper welding automation system includes:
Loading of braided connectors into the fixture
01
Alignment of terminal ends within positioning tolerance
02
Application of defined compression force
03
Delivery of welding current according to preset parameters
04
Release of the finished
connector

Why Copper Braid Processing Requires Dedicated Automation
The Material Can Twist During Feeding
Copper braid does not behave like a rigid metal strip. It may rotate, spread or move sideways while being pulled from the roll. If the guiding structure does not match the braid width and thickness, the material may enter the welding fixture at an angle.
The line uses adjustable guiding and clamping structures to keep the braid correctly positioned before the compacting cycle begins. The final guide design is confirmed from the customer's material sample.
01
Loose Strands Can Separate During Cutting
Cutting an uncompacted copper braid can leave loose or uneven strands at the cut edge. This increases the time required for manual correction and may make it difficult to position the part in a punching or welding fixture.
By compacting the required section before cutting, the machine creates a more stable cutting area. The result depends on the braid structure, compacting dimensions, heating parameters and blade condition.
02
Manual Length Control Creates Variation
When operators measure and cut each part separately, the finished length can vary with the positioning method and operator experience.
A servo-controlled feeding system can position the braid according to the programmed length. The achievable tolerance must be evaluated together with the material flexibility, roll tension, finished length and feeding arrangement.
03
End Dimensions Depend on More Than Pressure
Applying mechanical force alone does not always produce a stable compacted end. If the heat input is too low, the strands may remain loose. If the heat input is too high, the copper surface may discolor, the tin coating may be affected, or the braid may adhere to the electrode.
The welding current, heating time, pressure, electrode profile and cooling condition must be adjusted together. These parameters are established during sample testing and stored in the machine program for repeat production.
04
Separate Operations Increase Handling Time
When feeding, compacting, cutting and inspection are performed on separate machines, operators must repeatedly move and reposition the material. This can reduce output and introduce variation between operations.
Combining the required processes into one production sequence reduces intermediate handling. The level of automation should still be selected according to the production volume and number of product specifications; a fully automatic line is not always the most economical choice for frequent small batches.

Available Automation Configurations
Configuration |
Main production functions |
Recommended for |
| Semi-automatic copper braid welding machine | Manual material loading with automatic clamping, heating and compacting | Multiple products, sample production and smaller batches |
| Automatic compacting and cutting machine | Roll feeding, length positioning, heated compacting, cutting and unloading | Repeat production of standard copper braid shunts |
| Fully automatic copper braid processing line | Automatic processing with part transfer, monitoring and optional inspection | Higher-volume production with stable product specifications |
| Integrated connector assembly line | Copper braid preparation plus punching, terminal joining, busbar welding or assembly | Switchgear and electrical component manufacturers |
The appropriate configuration is selected from the required output, product range, available operators, workshop layout and downstream manufacturing process.
A customer producing several different braid sizes in low volumes may obtain better production flexibility from a semi-automatic machine with replaceable tooling. A customer producing one standard shunt in continuous batches may benefit from an automatic copper braid welding and cutting line.

System Advantages
Compared with conventional manual welding processes, the automated braided connector welding system improves both production consistency and operator workload.
Typical improvements observed in production include:
- Reduction in manual positioning errors
- More stable terminal compression thickness
- Lower variation in electrical resistance
- Reduced operator fatigue during long shifts
In facilities operating two or three shifts per day, automation helps maintain stable output even under continuous production conditions.
