DOUBLE-SIDED FULLY AUTOMATIC WELDING MACHINE 8 SKXD-700L

SunkaLead SKXD-700L Double-Sided Automatic Battery Spot Welding Machine

The SunkaLead SKXD-700L is a double-sided automatic spot welding machine for qualified cylindrical battery pack assemblies. It follows programmed welding routes after an operator positions the pack fixture, making it suitable for repeat jobs with a defined cell layout and connection pattern.

The machine automates the welding sequence rather than replacing every upstream assembly task. Cells, insulation, connection strips and the fixture must first be prepared correctly. For production planning, separate this preparation time from automatic welding time so that the expected output reflects the complete station workflow.

Double-sided operation provides access to connection patterns on both sides of the supported assembly. Stored welding programs allow an approved route to be recalled for a repeat pack design, while the PLC and operator interface coordinate the programmed process. This is useful where a production team handles several established layouts and needs controlled changeovers.

A stored program does not make different strip materials or cell terminals interchangeable. Electrode contact, welding energy, pulse timing and joint geometry still determine the weld. Establish an acceptable process window with representative samples, then use the agreed inspection method to check the joints.

Define the required weld locations from the actual pack drawing. The number of cells, joint positions and operator handling steps affects cycle time; a generic machine speed cannot predict completed packs per shift without that information.

Select the SKXD-700L around the fixture dimensions, cell arrangement, terminal accessibility and connection material. The fixture must hold the assembly securely while allowing each welding head to reach its intended positions. Check clearances around insulation, protruding tabs and other conductive parts before approving a layout.

For purchasing, provide the strip grade and thickness, proposed weld pattern and representative pack samples. Discuss how recipes will be identified, approved and protected from unintended changes. Confirm the supplied welding power configuration and required site services against the ordered machine rather than treating optional configurations as standard equipment. Include loading, inspection and removal in the production acceptance trial.

Applications

• Programmed nickel-strip welding for cylindrical battery packs.

• Repeat production of approved double-sided pack layouts.

• Controlled changeovers between established welding recipes.

• Battery connection-joint development and sample qualification.

• Assembly stations with fixture-based pack handling.

Installation Guide

Have trained personnel commission the machine with the specified electrical supply, pneumatic services and guarding. Verify the fixture location and welding-head travel without exposing a live assembly to unintended contact. Follow the manufacturer's procedure for setting up and checking the approved weld program.

Validate the first assembly after each recipe, fixture or material change. Keep the accepted settings and inspection results with the production record. Maintain electrode tips and remove contamination from contact surfaces at the prescribed intervals. Isolate all energy sources before maintenance and investigate inconsistent joints before restarting the batch.

Why Choose ARB Accessories?

ARB Accessories offers welding equipment alongside battery cells, nickel strips, insulation materials and pack-assembly accessories. Share the cell terminal, strip material, thickness and pack drawing when discussing this machine. Matching the equipment and consumables as one welding application helps procurement and production teams define a meaningful sample trial before placing an order.
