Automatic Gantry Five-Axis Fiber Laser Welding Machine
A gantry table with five interpolated axes and a 1500-6000 W CW fibre source: X, Y, and Z carry the torch, Rotary and Tilting set its angle, RTCP holds focus through the turn, and wire feeding runs 0.8-2.0 mm on 0.4 MPa air or argon.
Offers 1500–6000 W CW laser power at 1080 ±5 nm, with 0.8–2.0 mm filler wire and single, dual, or triple-wire feeding at 30–600 mm/s. Power and wire options adapt to joint thickness and gap requirements.
Supports compressed air, argon, or nitrogen at 0.4 MPa, with coaxial, side, or combined gas delivery. Select the shielding method based on material and joint type to reduce oxidation, porosity, and zinc fume interference.
Features a built-in water-cooling circuit with simple inlet and outlet connections, eliminating the need for a separate floor-standing chiller and supporting stable, continuous welding at rated power.
An 800 x 400 x 400 mm gantry with five interpolated axes: X, Y and Z carry a 1500-6000 W CW fibre source at 1080 nm, while a rotary axis and a tilting head set the angle of the joint. Rails and beam are dual-drive servo on linear guides, the moving modules hold +/-0.005 mm, and RTCP keeps the focal point on the seam while the axes turn, so defocus and incidence stay constant through a curve. Filler runs 0.8-2.0 mm through single, dual or triple feeders; shielding is 0.4 MPa air, argon or nitrogen, coaxial, side or mixed. Water cooling sits inside the cabinet and the controller takes CAD geometry directly, so a new part is programmed while the table keeps welding. Travel is 800 x 400 x 400 mm as standard and built to drawing beyond that.

The source sets the ceiling on machine life
Continuous-wave fibre source in four steps – 1500, 2000, 3000 or 6000 W at 1080 +/-5 nm – with the brand settled between MAX, Raycus and BWT by lead time. It sits inside the base, and it is the one part that stops the whole machine when it fails, which makes it the last part to buy at the bottom of the price list. Power is sized against the thickest joint in the drawing: 1500 W covers thin sheet, but pointed at 5 mm structural steel it produces for three months and then shortens its own life.
The chiller states its own nameplate
The unit fitted is the S&A CWFL-2000, matched to a 2000 W source, with a temperature display (24.0 C in this shot), an alarm-code chart and its own power switch on the front panel. A one-degree drift in water temperature is enough to move the operating point of the source and the collimating lens: on thin sheet it shows as penetration that wanders, and over a year as condensation on the optics. It stands outside the cabinet, so servicing needs no strip-down – and of the same-price machines we sampled, zero named a chiller brand.
Column and linear guide: the stiffness is in the rail, not in a wrist
The torch rides a linear guide on a single column and is lifted by the carriage, with a cantilever arm reaching the work position; the column is an aluminium profile with a steel rail, and the whole cable set runs in a drag chain instead of hanging across the beam path. Moving modules hold +/-0.005 mm over an 800 x 400 x 400 mm travel, larger than built to drawing. Against an articulated robot, error here does not grow with reach: a longer machine means a longer rail, not a softer posture.
The electrical cabinet: where most failures start, and the last thing anyone photographs
The cabinet is laid out by circuit: breakers and the main switch on one rail, safety relay and contactors on the next, numbered terminals, ferrules on every core, a copper earth bar along the bottom. Around eighty percent of welding-cell faults are electrical – a loose terminal, a welded contactor, a poor earth. Cables dressed and numbered turn diagnosis into ten minutes; a loom turns it into half a day. Of ten same-price machines sampled, exactly one showed the inside of its cabinet.
Rotary fixture: servo, planetary gearbox, three-jaw chuck
A servo drives a planetary gearbox through a coupling, and the gearbox turns a three-jaw chuck; the work is clamped in the chuck and indexed by the C axis. Circular seams on tubes, flanges and shafts come off this axis while the torch holds its attitude – roundness is set by the fixture’s rotational accuracy, not by an operator compensating. Chuck and gearbox are standard parts, so jaws or a gearbox can be replaced without waiting on the machine builder.
Torch: its own display, and only three wearing parts
The torch body carries a small display so power and process parameters are readable at the joint instead of on the main screen; below it sit the protective lens holder and the copper nozzle, with the shielding line entering from the side and the wire guide on the flank. Only three parts on the machine wear: the lens, the nozzle and the feed roll. The lens is retained by its own cap on the outside of the head, so changing it needs no strip-down and no refocusing – which buys back downtime and removes the temptation to keep welding through a dirty lens.
