Laser welding of metal

The essence of the method

Laser welding provides the highest precision of non-detachable connections of thin sheet parts. The welding energy required for the process is provided by a laser beam generated in the laser system. In this case, the energy that is absorbed by the metal causes its heating, but the time when the reflected part of the energy is lost. Sometimes the surface to be treated must be prepared by sandblasting or abrasive grinding.

An important role in the implementation of laser welding plays the thermal conductivity of the alloy. In particular, titanium can be welded at a much lower laser energy than gold.

The energy required for laser welding increases:

with increasing thermal conductivity of the processed material;

at a higher value of the reflection coefficient (for the workpiece);

with an increase in the penetration depth of the laser beam;

with an increase in the diameter of the laser beam.

To protect the welded workpiece from the workpiece from oxidation, it is preliminarily exposed to a stream of high-purity argon gas during the entire welding process.

Laser welding is a modern production method that offers many benefits and is applicable in many sectors for a variety of applications.

Supplier — AvekGlob Company — offers at affordable prices from the manufacturer various metals and alloys, in the quantity and assortment that are required by the customer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Laser welding equipment

Laser welding requires three components that should ideally be selected to produce convincing results: a control computer, a laser radiation source and a laser processing unit.

The laser source LSP includes a laser unit together with a power supply and water cooling. From here, the emitted light energy passes through the fiber optic cable to the processing unit, where all the necessary information from the control unit is also processed. Fiber-optic cable can have a maximum length of up to 80 m. The laser processing unit can work in two versions — with hard optics or with scanning optics.

Urgency of application

Laser processing, other than welding, is used in the following cases:

for the assembly or manufacture of jewelry;

for the production of laser marking and engraving of surface reliefs.

Laser welding is applicable to all materials and to any joint surfaces. In particular, when welding deep layers, high efficiency and high process speed are ensured, with an insignificant length of the thermal effect zone and in the absence of thermal deformation in parts. The depth of laser welding can be 10 times greater than the width of the weld.

Supplier — AvekGlob Company — offers to purchase various metals, alloys, welded structures in any quantity and range of sizes. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
