Introduction

In addition, modern heat exchanger manufacturers can to a certain extent require convenient and accurate production equipment. So the advanced welding technology is getting more and more important.

A state of the art Laser Fin Tube Welding Machine offers an extremely precise manufacturing process for quality fin tubes.

In contrast to traditional welding techniques, where an excessive amount of heat is generated and dissipated by a broader area, laser technology forms a concentrated source of heat. So it generates robust welds with low thermal distortion.

Furthermore, laser welding enhances fin tube quality, production consistency and service life.

In Bangwin Thermal, we have advanced fin tube production equipment & custom designed heat transfer solutions for clients worldwide.

Laser Fin Tube Welder Theory: So, what is a laser fin tube welding machine?

Les Laser Fin Tube Welding Machine is the equipment dedicated to the continuous welding of metal fins into copper – stianless steel or any other weldable material tubes with laser beams.

The machine uses focused laser energy.

Thereby also ensuring an exact coupling of the fin strip to the base tube.

The equipment can produce:

• Tubes à ailettes hélicoïdales
• Tubes à ailettes soudés
• Tubes à ailettes en acier inoxydable
• High-performance heat transfer tubes
• Customized fin tube products

Regarding fine tube welding, the laser fin tube welder has excellent control and precision than traditional welding equipment.

Operation of a Laser Fin Tube Welding Machine

A continuous process through a laser fin tube welding machine finishes the production.

The operator first works on the base tube.

The bushed fin then goes to the feeding system.

Subsequently, the laser beam heats up the contact area between fin and tube.

Next, rollers are used to press the fin onto a tube surface.

At the finish, the system turns into a constant welded fin tube.

La procédure prévoit :

• Une qualité de soudage constante
• High dimensional accuracy
• Grande résistance d'adhérence
• Low heat influence

As a result, fin tube performance gets better for manufacturers.

Laser Fin Tube Welding Machine Manufacturing Process

The multi-step production process as a whole

4.1 Préparation du tube de base

Before welding, the tube is prepared by the manufacturers.

Parmi les matériaux couramment utilisés, on trouve :

• Acier au carbone
• Acier inoxydable
• Acier allié
• Alliage de cuivre
• Alliage de nickel

Keep the surface of the tube clean

Therefore, the welding quality improves.

4.2 Alimentation en bandes de ailettes

The fin strip is automatically fed through the machine.

Le système d'alimentation contrôle :

• Tension de la nageoire
• Vitesse d'alimentation
• Alignment accuracy

Thus, the fin position stays constant.

4.3 Laser Welding Process

A laser system is very focused energy generator.

The contact area between the fin and tube is melted by laser.

The materials then bond metallurgically.

The area of the heat is very little so there is less deformation of the tube.

4.4 Formage d'ailettes hélicoïdales

Fin Strip on the Tube — Here, the machinery winds two wraps of fin strip around the plastic-covered recumbent tube.

Les opérateurs peuvent régler :

• Pas de l'aileron
• Hauteur de l'ailette
• Vitesse de soudage
• Vitesse de rotation du tube

Hence, the producers are capable of producing various fin tube varieties.

4.5 Contrôle qualité

Les fabricants vérifient :

• Résistance de la soudure
• Espacement des ailettes
• Rectitude du tube
• Qualité de surface

Thus, finished products can be released into production.

Advantages of Laser Fin Tube Welding Machines

5.1 High Welding Precision

The laser technology provides precise energy control.

As a result, the welding process does not fluctuate.

Besides that, the manufacturers ensure uniform product quality.

5.2 Low Heat Input

More heat is produced using traditional welding methods.

Nonetheless, laser welding only directs energy to a small target area.

Consequently, thermal deformation decreases.

This advantage protects sensitive materials.

5.3 Strong Fin-to-Tube Bond

The metallurgical bond created by laser welding is much higher.

Thus, fins are retained during working.

Additionally, the structural How is explicitly cold to augment vibration resistance.

5.4 Excellent Heat Transfer Performance

A well bonded fin also reduces thermal resistance.

As a result, finished tubes conduct heat more easily.

So the performance of heat exchanger is enhanced.

5.5 Large compatibilité avec les matériaux

There are various materials which laser fin tube welding machines supports.

Par exemple :

• Acier inoxydable
• Titane
• Alliages de cuivre
• Alliages de nickel
• Acier au carbone

As a result of which the manufacturers are able to manufacture & supply extended surface fin tubes.

5.6 Better Product Appearance

Laser welding is characterized by narrow and clean weld seams.

As a result, better surface finishes obtained for products.

This advantage helps premium heat exchanger applications.

5.7 Automated Production Capability

Modern machines include automation systems.

Parmi les fonctionnalités, on trouve :

• Commande par automate programmable
• Alimentation automatique
• Réglage numérique des paramètres
• Suivi de la production

This is how manufacturers improve efficiency and decrease the cost of labor.
