Handheld laser welding VS traditional welding and laser welding-Anne

/in /by

Handheld laser welding VS traditional welding and laser welding

Laser welding machine uses a high energy density laser beam as a heat source for efficient precision welding.

Since laser welding machine requires high precision for workpiece pre-machining, the position of the beam on the workpiece will not offset.

if theassembly accuracy or beam positioning accuracy of the workpiece does not meet the requirements.

So It is easy to cause welding defects, which limits the process capacity of laser welding to a certain extent. This is because the spot size is small and the weld is narrow after laser focusing.
In response to the limitations of the above laser welding technology, the market has gradually introduce a laser welding method with double wedge laser vibration, The realization method is to set a special swing vibration module on the welding head.

The application of wobble welding technology can make laser welding more widely used, and it can achieve high-efficiency laser precision welding for larger wider welds workpieces.

Advantages of handheld laser welding technology
In conventional laser vibration welding, the collimated beam is vibrated by a uniaxial galvanometer, and the spot focused by the focusing mirror is moved with the welding head to move
relative to the workpiece to form a weld having a certain amplitude, frequency and offset.
Compared to the first two vibration welding modes, the double wedge mirror rotational vibration welding produces a spiral weld seam by the vibration module mounted between the collimating mirror and the focusing mirror, so that the focusing spot moves while the welding head moves.

When the focal length is the same, the larger the torsion angle is,the larger the vibration amplitude is.

When the torsion angle is the same, the larger the focal length, the larger the vibration amplitude.

Therefore, double wedge vibration welding allows to widen the weld joint  while achieving better weld formability.

The person in charge should not only be in charge of the safety lock key and password of the welding machine, but also instruct the operator on how to use the welding machine and teach the relevant safety knowledge.

2, the establishment of a dedicated laser welding area.

The relevant responsible person is responsible for the establishment of a special laser welding area (with a fence and other similar devices separated from the other work area), while in the welding area to set up „loitering personnel prohibited near“ and other related signs.

3, the welding machine installed in a level, a solid place, not on the tilt of the place.

This welding machine uses three-phase AC 380V (50 ~ 60Hz) electricity.

4, the ambient temperature of 5 ° C-30 ° C humidity of not more than 85% of the environment in the use of the welding machine, the ambient temperature should not fluctuate too much.

Do not use the machine under the following conditions:
– There is dust, oil pollution of the environment.
– A vibrating environment.
– Corrosive environment.
– High-frequency noise environment.
– Humid environment.
(CO 2, NOx, or SOx) in atmospheres containing high concentrations of carbon, nitrogen and sulfur oxides.

5, in the winter if the ambient temperature dropped below 0 ° C, the water tank will be frozen, the water tank may crack.

Therefore, special care in the winter to ensure that the ambient temperature of the welding machine not less than 0 ° C. If the ambient temperature is below 0 ° C, drain the water from the tank and refer to the relevant section.

6, if the ambient temperature changes in the YAG laser rods and lenses will form water vapor, which will affect the use of welding machines.

Therefore, as far as possible to prevent the dramatic changes in ambient temperature. If the water vapor has been formed, then the machine must be warmed up after a while and then use the machine.

How thick can a 1000 watt handheld laser welding machine be welded?-Anne

/in /by

How thick can a 1000 watt handheld laser welding machine be welded?

Of course, the higher the power, the thicker the thickness of the welding. The laser welding is about the penetration/melting pool. The thickness of material also influence it ,so it can analysis laser welding material according to the following points.

Material

2. Thickness
3. Requirements
4. Welding angle
5. Pulling requirements

Different metal materials have different melting points:

A complicate things is The parameter setting of different kinds of materials  , the thermal properties of welding materials vary with temperature; the difference of absorption rate of laser with different kinds of metals and its variation with temperature; the formation and evolution mechanism of molten pool; the melting zone and heat affected zone of solidification process Organizational evolution; formation of laser welded joint defects, welding residual stress and deformation. However,  material properties on the microstructure and macroscopic properties of the weld is the key problems the formation and evolution mechanism of the weld pool and the formation of weld defects and residual stress during the solidification process of the weld pool.

So laser welding machine .

Is laser welding related to the thickness of the board?

The properties of the material relation to the depth of laser welding , and of course the material thickness, welded carbon steel, and titanium are certainly not possible with the same parameters.

For example, welding: 2mm thick stainless steel plate, requires penetration, the finer the weld, the better.We recommend to use 1000W fiber laser welding, the speed can reach more than 1 m / min

For example, welding: welding 3mm stainless steel plate with 500W laser welding, one-sided welding can penetrate 1.5mm thick material, if both sides are welded, each 1.5mm, the material of 3mm thickness will be penetrated;

So laser welding machine .

For example, welding: 1000W welding 5mm stainless steel plate can also be welded, one side can be molten pool 3mm, some production port tension requirements are not high, can also meet the requirements, if slow down, slowly walking welding may also be deep 5mm

Thickness of different power welding of handheld laser welding machine.So laser welding machine .

The hand-held laser welding machine wide application on the market. Due to its cost performance,public recognize its in  life application.

What protective gas should I use for laser welding?（II)-Anne

/in , /by

What protective gas should I use for laser welding?

Type of protective gas

Commonly used laser welding protective gases are mainly N2, Ar, He, and their physicochemical properties are different, so the effect on the weld is also different.

1. Nitrogen N2—a welding protective gas of stainless steel

The ionization energy of N2 is moderate, higher than that of Ar, lower than that of He, and the degree of ionization is generally under the action of laser, which can better reduce the formation of plasma cloud, thereby increasing the effective utilization of laser. Nitrogen can react with aluminum alloy and carbon steel at a certain temperature to produce nitrides, which will improve the brittleness of welds and reduce the toughness, which will have a great adverse effect on the mechanical properties of welded joints.

Therefore, it is not recommend to use nitrogen.Protective Aluminum and carbon steel welds.The nitride produced by the chemical reaction between nitrogen and stainless steel can improve the strength of the welded joint and improve the mechanical properties of the weld.

Therefore, when welding stainless steel can use nitrogen as a shielding gas

2. Argon Ar—-high cost performance, the most conventional protective gas

The ionization energy of Ar is relatively low, and the degree of ionization is high under the action of laser, which is not conducive to controlling the formation of plasma cloud, which will have certain influence on the effective utilization of laser, but the activity of Ar is very low, and it is difficult to chemicalize with common metals.The reaction, and the cost of Ar is not high, in addition, the density of Ar is larger, which is favorable for sinking above the weld pool, and can better protect the weld pool.so it is a conventional shielding gas.

3. Helium He—the best but also the most expensive protective gas

He has the highest ionization energy and low ionization under the action of laser. It can control the formation of plasma cloud very well.So The laser can work well on metal, and the activity of He is very low, and it does not chemically react with metal.Very good weld protection gas, but the cost of He is too high, generally not used in mass production products, He is generally used for scientific research or products with very high added value.

What protective gas should I use for laser welding?

The role of shielding gas in laser welding

In laser welding, the protective gas will affect the weld formation, the weld quality, the weld penetration and the width of the weld. In most cases, the blowing of the shielding gas will have a beneficial effect on the weld, but it will not be used.  Good may also have an adverse effect.

The positive effect of shielding gas on laser welding

1) Proper blowing of protective gas will effectively protect the weld pool from oxidation and even avoid oxidation.

2) Proper blowing of the shielding gas can effectively reduce the splash generated during the welding process and protect the focusing mirror or the protective mirror.

3) Proper blowing of the protective gas can promote uniform spreading of the weld pool during solidification, so that the weld bead is formed evenly and beautifully.

4) Proper blowing of the shielding gas can effectively reduce the shielding effect of the metal vapor plume or the plasma cloud on the laser , increase the laser energy reaching the surface of the workpiece, and increase the effective utilization of the laser.

5) Proper blowing of protective gas can effectively reduce weld porosity.

As long as the gas type, gas flow rate, and  select correct blowing method , you can get desire effect. However, incorrect use of shielding gas can also adversely affect welding.

Adverse effects of improper use of shielding gas on laser welding

1) Incorrect blowing of shielding gas may cause the weld to deteriorate:

2) Choosing the wrong type of gas may cause cracks in the weld and may also result in a decrease in the mechanical properties of the weld;

3) Choosing the wrong gas blowing flow rate may cause the weld to be more oxidized. (whether the flow rate is too large or too small)

4) Choosing the wrong gas blowing method will result in the weld not achieving the protective effect or even the basic protection effect or negatively affecting the weld formation;

5) Insufflation of the shielding gas will have a certain influence on the weld penetration, especially when the thin plate is welded, the weld penetration will be reduced.

Hope it is helpful for you,we will share you the gas type in the next article.
