6 factors will influence the effect of laser deep penetration welding

Deep penetration, or deep penetration welding.Common for welding thicker materials with high laser power.

In deep penetration welding, the lasers are focused together to create a very high power density on the workpiece.

In fact, the spot where the laser beam is focused will vaporize the metal, causing a blind hole (ie, deep penetration) to appear in the molten metal pool. The metal vapor pressure will block the surrounding molten metal, so that the blind hole is always open during the welding process.

The melt at the vapor-melt boundary and deep-melt hole walls will absorbed laser power.

The focused laser beam and deep penetration holes move continuously along the welding trajectory.

The welding material melts in front of the deep penetration hole and solidifies again at the back to form a weld.

so laser welding machine .
The factors that affect the effect of laser deep penetration welding are:

1.Laser power density

so laser welding machine .
The premise of deep penetration welding is to focus the laser spot so that it has a sufficiently high power density, so the laser power density has a decisive influence on the weld formation. Laser power controls both penetration depth and welding speed. For a laser beam of a certain diameter, when increase the laser power, the penetration get more  deep and the welding speed get more accelerate.

There is generally a critical value for the laser power to reach a certain welding penetration. When it is reach critical value, the molten pool boils violently, and when exceed it , the penetration depth will decrease sharply. In addition, due to the action of metal vapor, small holes will form in the molten pool, and the small holes are the key to the realization of deep penetration welding.

The focal spot power density is not only proportional to the laser power, but also related to the laser beam and focusing optical path parameters.

2. Welding speed

so laser welding machine .
During deep penetration welding, the welding speed is inversely proportional to the penetration. and when maintain  laser power , if  increase the welding speed, it will reduce the heat input  and the penetration depth.

so laser welding machine .
3. Focus position

so laser welding machine .
In deep penetration welding, to maintain sufficient power density , the focus position is critical.so laser welding machine .

The change of the relative position of the focal point and the workpiece surface directly affects the width and depth of the weld.

Only when the focal point is located at a suitable position in the workpiece surface can the obtained weld be formed into a parallel section and obtain the maximum penetration depth.

Spatter-free welding, we are serious!—Winnie

Spatter-free welding, we are serious!

In recent years, fiber lasers have been more and more widely used in the field of metal welding and cutting. However, in some welding applications, there are still unsatisfactory effects, for example, splashes are easy to occur during welding …

01, What effect does splashing have?

After the laser welding is completed, so there are many metal particles on the surface of the material or workpiece, which are attached to the surface of the material or workpiece. This is the particulate matter generated by the splash. These particles not only easily scratch the base material, pollute the protective glasses of the welding helmet, but also contaminate the filter and frosted glass of the camera of the equipment, resulting in rework of components, damage to components, and even more serious downtime.

In particular, the automotive industry requires a large amount of welding of specific materials such as galvanized steel, copper and aluminum. In the past, the way to eliminate splashes was to sacrifice the inherent advantages of fiber lasers, so which greatly reduced processing capacity and efficiency.

Until its appearance …

02, Small splash welding tool

YLS－6000 ／ 9000－AMB Beam Mode Tunable Fiber Laser

AMB laser welding with low spatter

AMB can produce a larger and more stable keyhole, so making it easier for metal vapors to escape; the ring beam minimizes the kinetic energy of the vapors that escape, thereby minimizing splashing.

On the other hand, AMB can make the molten pool more stable, and no further melting occurs after the formation of a more stable keyhole. The ring beam softens the material and deflects towards the bottom of the bath, significantly reducing splashing.

03, Industry application cases

Minimum spatter welding of copper

Ordinary high spatter welding AMB less spatter welding

Process: 3 mm overlap weld

Material: 0.2mm nickel-plated copper + 0.2mm nickel-plated copper + 2.0mm copper

Welding speed = 120 mm / s

Minimum spatter welding of aluminum

So ordinary high spatter welding AMB less spatter welding

3 mm overlap weld

So material: 0.2mm aluminum + 0.2mm aluminum + 2.0mm nickel-plated copper

Welding speed = 45 mm / s

Beam mode adjustable for minimal splash

Benefiting automakers a lot

Advantages for traditional car manufacturing

Improve welding speed of auto parts

So reduced porosity and zero-gap welding of galvanized steel

Eliminate controlled gaps that may add extra cost

Improve the post-weld mechanical properties of the blank material

Low spatter reduces surface roughness and improves formability

Spatter-free welding, we are serious!

Battery copper and aluminum welding

So advantages for electric vehicle manufacturing

For welding copper and aluminum cells

Improve welding speed and welding stability

Improve welding aesthetics and air tightness of aluminum battery case

High-speed welding of deep-drawn thin-walled lithium battery cases

Non-spatter welding of hot-dipped aluminum steel plate

Mainly used in automotive parts, so thermal equipment, building materials, etc. Welding beauty is enhanced, 12m / min is completely penetrated and the weld has no pores.

welding ability of handheld welding machine

Most of customers choose welding machine to weld metal.Such as stainless steel,carbon steel,aluminum,etc,.But customers always are confused on the welding ability.How to choose the suitable machine watt?Here we would like to share more with u.

The welding machine is not same as the the cutting machine.we can not only say ability.
Generally we use two kinds of words to learn the welding capability.
Welding depth(melt depth) and welding ability.

 Melt depth

1.Firstly,Welding depth is not related to the welding situation.it is the melt depth.
for 400 w,steel:2.5mm .aluminum:0.25mm
and then,for 500 w,steel:3mm. aluminum:0.3mm

Welding ability

2.Secondly,Welding ability(it is related to ur welding situation,such as the Stitching welding , Penetration welding)

1)Firstly,for stitching welding

For 400 w,steel:1.5mm .aluminum:1mm
For 500 w,steel:2mm .aluminum:2mm

2)Secondly,for Penetration welding

For 400 w,steel : 1mm
For 500 w,steel: 1.5mm

As u know,aluminum is high-reflective material.so it is difficult to do penetration welding.So we do not suggest that.

 

In the end,in a word, the above ability is only our experience.Different materials and situation,different ability.

Hope this can help u to learn more about the machine ability.

Here is our handheld welding machine photo

fiber laser welding machine on gears welding industry-Max

/in /by

fiber laser welding machine on gears welding industryd

Nowadays gears are widely used in automotive manufacturing, medical equipment, machinery manufacturing, aerospace and other fields. And the welding process of the gear directly affects the performance of the product. The traditional welding process has the disadvantages of high heat input and easy deformation. So it cannot meet the high precision requirements of the gear. For now both vacuum electron beam welding and laser welding can meet the requirements of gear welding process. However, vacuum electron beam welding requires a vacuum environment. and it is with  low efficiency, expensive equipment. Therefore it is not suitable for industrial production. Therefore, laser welding is more suitable for gear welding and laser welding technology has become an important condition for gear welding applications.
After the high energy density spot of the fiber laser acts on the surface of the material, we can obtain a large aspect ratio (ratio of weld penetration to melt width). Through proper process adjustment, the amount of deformation of the gear after welding is small and no need subsequent processing. The laser welding assembly clearance requirement is one of the main reasons for limiting its application. And the gear assembly is an interference fit. So the clearance fit requirement during the welding process is basically negligible.

Gear assembly form


The fiber laser is for the welding test and the gears were pre-welded. And different welding speeds can receive the different weld penetration and melt width. It can be seen from the figure that the weld seam is obviously „nail shape“. Meanwhile there is no obvious welding heat affected zone. And the weld seam has no defects such as pores and cracks. Fiber laser welding can meet most gear welding process requirements.

Gear assembly form


Fiber laser welding has the characteristics of fast welding speed, small deformation after welding and no post-weld treatment. Now it is very popular in various industries of the national economy. China fiber laser is now specializing in fiber laser research and development and production. What’s more, provides customers with a wide range of application process technology support. So to provide customers with high-quality fiber lasers is the driving force behind the continuous efforts and progress of the company.

Laser machine application in Jewelry fields – Alex

/in , , /by

Jewelry processing is becoming more more automatic. Before people may process it by hand with knife, special screw, saw etc. Mow more and more people replace traditional tools with laser machine. as laser processing on jewelry is much more fast and precision, we can use it do many complex pattern and many hard work.

In jewelry manufacturing fields, fiber laser cutting machine, fiber laser marking machine and laser welding machine all have wide application.

  • Fiber laser cutting machine

Small size high precision fiber laser cutting machine is very expensive. But it become more and more popular for some big jewelry manufacturer. Fiber laser cutting machine have very fast cutting speed and very high cutting precision for jewelry working. For one name necklace, few seconds it can finish it. Of course, due to usually we cut thin gold and silver sheet, it need special fixture. Other wise the sheet will be deformation during cutting as cutting process need blow auxiliary gas.

Additional, gold and silver belong to high reflective material. Its cutting need special laser soruce. The laser head also need do special structure. If you need know more details about it, you can send me message by email.

  • Fiber laser marking machine

Fiber laser marking machine should be the most popular laser machine on jewelry processing, we can use it both on marking and cutting. We can use any power laser machine on gold, silver, brass and other metal marking. The marking content like picture, pattern, letter, number and so on. Otherway we can use it on deep engraving and thin gold&silver sheet cutting. Now many people use it cut necklace, especally name necelace.

Add one rotary axis for fiber laser marking machine, also we can use it mark rings both inside and outside.

  • Laser welding machine

Laser welding machine should be the earlist laser machine which used on jewelry processing. For rings welding, reparing and chain manufacturing, it have good performance. Now there is special type especially used on jewelry welding.

If you want to learn more about laser machine, we can talk more.
