Automatic Continuous Laser Welding Machine for Pillow Plates
Fiber laser welding system for single and double embossed pillow plates in stainless steel and titanium. Work areas up to 12,000 mm, configured to your plant layout.
Laser power options: 1000 W / 1500 W / 2000 W / 3000 W / 4000 W / 6000 W
What is a pillow plate laser welding machine? It is an automated fiber laser system that welds two metal sheets together along a continuous seam pattern. The sheets are then inflated into pillow-shaped channels, forming a heat-transfer plate used on tanks, chillers and ice banks.
Key features
Continuous fiber laser welding
The laser is delivered by optical fiber and runs continuously along the seam, giving a fine, uniform weld line.
Low distortion, pore-free welds
Fast welding speed, minimal deformation and no bubbles in the weld.
Six power options
1000 W to 6000 W, matched to your plate material, thickness and output.
CCD vision monitoring
External HD CCD camera for positioning and live observation of the welding process.
Non-contact welding
Reaches areas that are difficult to access with conventional welding methods.
Servo-driven motion
Servo motor drive with an optional 80 mm rotary device.
Custom work area and layout
Welding host and worktable are configured to your production site and automation needs.
Established components
Laser sources from Raycus, IPG, Max or JPT. Weld heads from WSX, Raytools or Precitec.
Long laser service life
Imported laser source, rated by the manufacturer for 10+ years of service.

Why laser welding for pillow plates
Conventional pillow plate production often relies on spot or resistance welding, where welds are made point by point. Continuous laser welding runs one uninterrupted seam. That means a more uniform weld, lower heat input, less distortion and a process suited to automated, high-volume production. When the plate is inflated, the pillow structure creates turbulent flow in the fluid, which improves heat transfer. Pillow plates are also easy to clean.

Frequently asked questions
What laser power do I need?
Maven Laser offers 1000 W, 1500 W, 2000 W, 3000 W, 4000 W and 6000 W. The right choice depends on your plate material, thickness and production volume. Send us your specifications and we will recommend a configuration.
What is the difference between single and double embossed pillow plates?
Single embossed plates combine a thick and a thin sheet, and only the thin sheet bulges. They are common as tank jackets. Double embossed plates use two identical thick sheets that both bulge. They are common in chillers, evaporator panels and ice banks.
Which materials can the machine weld?
Stainless steel and titanium are the common pillow plate materials. Contact us with your grade and thickness so we can confirm the right setup.
What is the maximum plate size?
Standard work areas are 1500 × 3000 mm, 500 × 6000 mm and 500 × 12000 mm. Custom sizes are available.
Which industries use laser welded pillow plates?
Dairy (bulk milk coolers), brewing and winemaking (fermentation tanks), chemical processing, and refrigeration (falling film chillers and ice banks).
Which laser and weld head brands are used?
Laser sources from Raycus, IPG, Max or JPT, and weld heads from WSX, Raytools or Precitec.
What power supply, gas and cooling are required?
AC 380 V ±10%, 50 Hz, 3-phase power; argon or nitrogen shielding gas; and a water chiller using distilled or pure water. Chiller capacity depends on laser power.
Can the machine be customized to my production line?
Yes. The welding host and worktable are configured to your site, including work area and level of automation.
What is the weld width range?
0.5 to 5 mm.
