A misplaced battery weld is found too late to be cheap

Battery terminal and tab welding fails quietly: a weld that looks acceptable at the station shows up as a reject or a warranty claim at end-of-line testing. Resistance welding adds electrode wear into the process, and placement accuracy drifts with every dress cycle. For pack integrators the cost is not the weld - it is the module that has to be opened.

Placement drift. Electrode wear and manual alignment move the weld point; defects surface downstream.
Material mix. Aluminum and copper tabs reflect and conduct differently; one parameter set does not cover both.

What the laser route changes

Xinhong's battery welding machines put the verification before the weld: vision positioning aligns the 1500W beam to the tab on the battery terminal machine, the 3D rotary workstation tracks circumferential seams with capacitive height sensing, and the production line variant selects the program by vision per module. Parameters for your exact tab stack are established on your own parts in a weld trial - not assumed from a datasheet.

How the process window is proven: you send tab drawings and reject history; we run a weld trial on your parts and return the samples, the parameter window and the recommended configuration with the quotation.
Buyer value: place every terminal weld by vision instead of by eye, weld aluminum and copper with per-material parameters, and validate the whole window on your own tab stack before you commit.

Application case

EV pack integrator: terminal placement verified by vision before every weld

EV pack integrator: terminal placement verified by vision before every weld

Who: an EV battery pack integrator welding terminals and tabs on pack assemblies. Machine: Xinhong battery terminal laser welding machine with 1500W fiber laser and vision positioning. Problem it solved: terminal welding on aluminum and copper tabs demands precise placement - resistance welding electrodes wear and wander, and misplaced welds only surface at end-of-line testing. Before: electrode dressing and placement checks were constant bench work. Now: vision positioning aligns each weld to the tab before firing, and placement is verified on-screen rather than by operator eye. Where the numbers come from: the battery terminal product specification (1500W fiber laser, vision positioning, aluminum and copper tab welding) and the integrator's own weld-trial and first-article records on their tab stack; process windows for their exact tab design were established in the trial.

Application based on customer feedback; individual results depend on materials and production conditions.

Energy storage integrator: housing seams welded in one rotary setup

Energy storage integrator: housing seams welded in one rotary setup

Who: an energy storage integrator welding terminals on prismatic cells assembled into rack modules. Machine: Xinhong 3D rotary laser welding workstation. Problem it solved: circumferential and seam welds on cylindrical and prismatic housings required repositioning between welds, and each re-clamp risked moving the part. Before: operators repositioned parts manually between weld passes. Now: the 4-axis CNC rotary turntable and capacitive height tracking hold the part while the seam runs around it, so multi-angle welds complete in one setup. Where the numbers come from: the workstation specification (4-axis rotary turntable, 2000W fiber laser, capacitive height tracking for circumferential welding) and the integrator's weld trial reports on their own cell hardware.

Application based on customer feedback; individual results depend on materials and production conditions.

Module assembler: program selection moves from operator memory to vision

Module assembler: program selection moves from operator memory to vision

Who: a battery module assembler moving from bench welding to module-level automation. Machine: Xinhong automated production line laser welding machine with conveyor integration. Problem it solved: module assembly volume outgrew bench stations, but quality depended on operators loading parts correctly. Before: every module depended on manual loading discipline. Now: conveyor-integrated part flow with vision-based part recognition selects the weld program per module type. Where the numbers come from: the production line specification (conveyor integration, 2000W fiber laser, vision-based part recognition, batch scheduling) and the assembler's acceptance run on their module variants.

Application based on customer feedback; individual results depend on materials and production conditions.

Customer ratings

“Use case: terminal welding on pack assemblies, evaluated through a weld trial on our own tab stack. | Assessment: what convinced us was seeing placement verified on-screen before each weld - our old bench relied on operator checks after the fact. | Verified point: the battery terminal specification lists vision positioning with a 1500W fiber laser, and the trial parts matched our first-article requirements. | Source: weld-trial report and first-article inspection records, 2025.”
Process engineerEV pack integrator, EU (anonymised)
“Use case: prismatic housing seams in rack modules, assessed during commissioning. | Assessment: one rotary setup per housing replaced our re-clamp routine, and that is where our handling damage came from. | Verified point: the workstation specification lists the 4-axis turntable and capacitive height tracking, both demonstrated on our housings at commissioning. | Source: commissioning record, 2025.”

Buyer FAQ

Which battery tab materials and thicknesses can you weld?+

The battery terminal machine pairs a 1500W fiber laser with vision positioning for aluminum and copper tab welding. Your exact tab stack (thickness, plating, busbar design) defines the process window - we establish it in a weld trial on your own parts before quoting.

How do you prevent misplaced terminal welds?+

Vision positioning aligns each weld before firing, and acceptance runs record placement on your parts. Send your tab drawings and current reject modes - we run a trial and return the weld samples with the process window in the quotation.

Do I need a rotary station for cylindrical cells?+

Use the 3D rotary workstation when housings need circumferential or multi-angle seams: its 4-axis turntable and capacitive height tracking complete housing seams in one setup instead of repeated re-clamping.

What details should a battery welding inquiry include?+

Tab drawings with material and plating, busbar design, target daily module count and current reject modes. We confirm machine configuration and the weld-trial plan together in the quotation.
