For reasons of drinking water quality, hygienic requirements, weight reduction and quality, hot water tanks are made of enamelled steel or stainless steel. Stainless steel tanks have the advantage that they are particularly corrosion-resistant and therefore durable and do not require any further corrosion protection measures.
To participate in different markets with differing regulations, you therefore need an adaptable production solution.

Our machines and systems provide the flexibility you need, optimal production processes and high-quality work results in the production of stainless steel boilers. They do so based on two factors:

  • the use of laser welding
  • intelligent clamping technology

Thanks to the innovative use of these technologies, you can use our machines to manufacture a broad spectrum of boilers:

Advantages of laser welded boilers

Companies that use laser welding to produce stainless steel boilers benefit in several ways: In addition to high visual quality, the process ensures better profitability and numerous technical advantages.

At a glance: Advantages for better profitability

  • 3 to 5 times higher welding speed means more output in the same time.
  • Butt welds instead of overlapped connections help save material.
  • Lasers create significantly less weld spatter and, therefore, require less reworking.

Technical advantages

  • Butt welding does not prevent welded corrosion edges.
  • Less heat input during the welding process minimizes thermal distortion.
  • Laser welding reduces the risk of fusion defects.
  • Even welding creates uniform wall thicknesses and good tension distribution.
  • Butt welds simplify welded connections for bases/covers
  • Optimal conditions for coating tank interiors and outer shells

Laser welding machines and systems are our speciality. Our engineers would be happy to explain how the joining process can be optimally integrated into your production.

Intelligent clamping technology saves time in boiler manufacturing

Our clamping technology also makes boiler production more profitable. It facilitates automated, accurate welding of the stainless steel cylinder through optimal joint pressing. This automation saves a significant amount of time in the production process.

The same applies to joining bases and covers. Both elements can be pressed and welded simultaneously to the base using our clamping technology. The laser welding device first creates a connection at individual points. Then the clamping system applies pressure while the optic welds a seam around both sides of the water heater.

You are welcome to contact our technical consultants to learn more about our clamping technology.
