  1. Dfifferent fiber laser welding machine power lead to different laser welder cost

Different laser welding machine power : such as 200w laser welder / 400w laser welding machine / 600w fiber laser welding machine / 1000w laser welder /1500w laser welder /2000w laser welder /3000w laser welder etc.

The truth is the higher power, the higher the laser welding machine price.

For example, our Changtai company’s 200W jewelry laser welder price is 3500-4500 dollars: the price of the 1000W optical fiber handheld welding machine ranges from 8000-10000 US dollars. The laser is the core component of the fiber welding machine. The greater the power, the higher the laser welding machine price. In addition, the higher the power, the higher the requirements for the cooling system.

  1. Different brands of laser welding machine accessories with different laser welding machine price

There are many accessories for laser welder. Imported laser welder parts are a little more expensive than domestic ones. There are also many brands of laser welder accessories in China, and the laser welder parts prices are also uneven. For example, there are three major brands of laser welding machines: MAX / RAYCUS / JPT. Our Changtai Company chooses laser brands with good product quality and stable performance from the perspective of use cost and maintenance cost. In addition, the brands of welding heads are also different. At present, the most popular laser welder head in the market are Hanwei and Wanshunxing. We can make laser welding machines according to the needs of customers.

  1. Different customization laser welder needs, different laser welding machine price

When customers choose laser welder, they will add accessories according to their different work requirements.

Install a CCD camera monitoring system on the jewelry welding to clearly see the welding process. The handheld welding machine adds a manipulator instead of manual welding. Some laser welding processes require customized automated fixtures or modification of the workbench.

These customized laser welder requirements have caused the increase in the manufacturing cost of the laser welder, and have put forward higher requirements on the production technology, which also directly affected the sales price of the laser welding machine.

  1. After-sales service also would be a laser welder cost for a laser welding machine manufacturer

Yag welding machines:like jewelry welding machines crystals ,Xenon lamps are consumables and have a certain service life. The lasers of fiber welding machines work for about 100,000 hours. It needs to be replaced after expiration.

Our Changtai company provides laser welder consumers with a strong after-sales service guarantee and timely provision of these consumables.

When there is a problem with the laser, return to the factory for repair or send a new laser to the customer as appropriate. Solve current problems for customers in a timely manner.

In general, when customers buy laser welding machine, first they must clarify how their products need to be configured with the welding machine, pay attention to the detailed laser welder parameters :power, configuration, performance, etc., and put after-sales service in an important position.

Laser welding machine can be used for various metals, such as titanium welder, nickel, tin, zinc, copper, aluminum, chromium, bismuth, gold welder, silver, etc., as well as welding of the same materials as steel and Kovar.Laser welder laso used in various dissimilar metals, such as copper nickel, nickel titanium, copper titanium, brass copper, low carbon steel copper.

Many industries and sectors rely on laser welder. The most common ones include:

  • Automobile industry
  • Aerospace industry
  • Assembly manufacturing industry
  • Engineering and IT department
  • Construction industry
  • Sheet metal, chassis and water tank
  • Various hardware lights
  • Door and window frame
  • Kitchen and washbasin hardware
  • Billboards, advertisements, etc.

The main purpose of laser welding machine is to make a connection of sufficient strength between the two sides of the welding materials. The laser welder strength has a great relationship with the laser welding equipment power and the work speed as well as the welding material.

  1. Under the same laser welding machine power, the welding speed directly affects the welder strength. The faster the laser welders peed, the narrower the weld seam, then the welding cannot be formed quickly. In other words, the faster the laser welder speed, the weaker the laser welding strength. Besides, the faster the welding speed, the shallower the penetration, so when welding thin plates or materials with better weldability, high-speed welding can be used, but it’s better to use low-speed when laser welding machine work on thick plates or difficult-to-weld materials.
  2. When the laser welding machine speed remains the same, the higher the laser power, the better laser welder intensity. That is to say, when the laser welding machine’s power is increased from 1000W to 2000W, the penetration depth will increase and the laser welding strength will also increase.

Our Changtai company is currently doing strength experiments on handheld welding machines

1) 1000W laser welding machine can weld stainless steel within 3 mm.

2) 1500W laser welding machine can weld stainless steel within 5 mm.

3) 2000W laser welding machine can weld stainless steel within 8 mm.

If there is a relatively large weld (greater than 0.3mm) between the two materials, then we would recommend the customer to use an automatic wire feeder.

In addition, the laser welder strength is also affected by the welding material, no matter there is gas assist during welding or not. Different materials have different absorption of laser light. The surface state of the material (the degree of smoothness) has an important influence on the absorption rate of the laser; The shielding gas is assisted to prevent the workpiece from being oxidized during welding, protect the focusing lens, and dissipate the plasma shield generated during high-power laser welding. Then the welding strength will be further improved.

In summary, there is a suitable welding speed range for a certain laser power and a certain thickness of a specific material. When the relevant conditions are met, the laser welding machine strength is naturally very strong. It is definitely larger than the traditional welding process on the market.

Laser welding is different with MIG

Laser welding and MIG welding are the two most important welding forms on the market.

Compared with MIG welding, laser welding has obvious advantages and disadvantages.

The advantages of laser welding lie in the improvement of laser welder production efficiency, no pollution, and high weld quality in sheet metal welding.

  1. The laser welding machine speed and penetration ability is strong.

The laser welder penetrate materials ability compares with traditional MIG welding: When work on the thick materials welding, the use of MIG requires multiple welding again and again. The speed of laser welding machine is three to five times faster than MIG welding, and in the whole welding process, MIG welding needs to be performed before welding, cleaning and polishing after welding. Although the bevel angle needs to be polished in advance for laser welding at positions above half an inch, it is much smaller than the entire bevel angle required for MIG welding. For materials with a thickness of half an inch, laser welding will be 15-50 times faster than MIG. If the post-processing time of MIG welding is added, the speed of laser welding will be even faster.

In addition, laser welding sometimes does not need to use filler metal or shielding gas, and does not need to be polished after the weld is completed, so use the laser welder will save much time and money and improves production efficiency.

  1. During the welding work, the more heat input in welding, the greater the residual stress generated, and the greater the degree of buckling, deformation and shrinkage.

Compared with MIG, when laser welding is welding on thin plates, MIG welding transfers more heat and has a longer cooling cycle, while laser welding reduces the heat input by about 85%, transfers heat energy with a very small beam, and only melts the part In the area, the parts cool very quickly, thereby minimizing the deformation and welding metallurgical effects.

According to this advantage of laser welding machine, it is often used in industries that require high aesthetic quality or aesthetic effect, such as electrical appliances, signs or elevator panels.

  1. Laser welding is non-contact, there are almost no wearing parts, and there is no risk of tungsten immersion contamination.

Laser welding machines have such advantages, so why is MIG still enthusiastic?

  1. The initial cost of the MIG system is usually lower than that of the laser system. However, the laser cost has been declining,
  2. MIG welding is easier to automate, only need to control welding speed, voltage, amperage, angle and other parameters. In addition, although MIG welding accuracy is worse than laser welding, but the welding is relatively strong.

For welding processes that do not require welding precision and precision, MIG welding is a good choice.

Now in development, the MIG welding process and laser welding are combined together. Achieve the most perfect welding process

If you want to buy the laser welder, the first consideration for welding work is whether to use pulse laser welding or continuous laser welding. This problem not only involves fiber laser welding machine cost, laser welding machine work process, laser welder efficiency, but also factors such as later equipment transformation and upgrading, so we must carefully consider whether it is pulse laser welding or continuous laser welding from different aspects.

Continuous laser welding: the laser core of the continuous laser welding machine at this stage is a high-power which is more than 1000 watts, and this laser welding method is generally used for welding plates with a thickness of more than 1 mm. Continuous laser welding with fast welding speed and low thermal deformation are also suitable for intensive welding such as machinery, automobiles, ships and other industries.

Pulsed laser welding: Compared with continuous laser, pulsed laser welder has larger output power and is suitable for laser marking, cutting, welding, etc. Pulsed laser is mainly used for spot welding and seam welding of metal materials with a thickness of less than 1mm. The overall temperature rise of the laser welding machine workpiece is small, and the heat influence range is small, which avoids the characteristics of metal melting or deformation during the laser welding machine working process.

Pulsed laser has a large number of applications in 3 C product on shells welding, lithium batteries welding industry, electronic components, mold repair welding and other industries.

So how to choose the fiber laser welding method is a more important issue. In order to better facilitate the selection of customers, our Changtai company makes the following suggestions:

  1. When use a laser welder, according to the welding process, choose different laser welding methods

Continuous laser welding has a very high frequency of light emission. In an ideal welding state, a uniform and smooth weld can be obtained, which does not require post-processing. However, because of the low frequency of light emission in pulse welding, a flat fish-scale weld or single welding spot is obtained in the work, which is similar to a argon arc welding weld. If the workpiece processed by the customer does not have too many requirements on the surface, you can choose Pulse laser welding machine.

  1. According to the laser welder application to choose different welding method

Continuous lasers are characterized by high stability, low power consumption, and high efficiency, and their market share continues to expand. At present in the market, continuous laser welding machine is mostly used for deep penetration welding. For example, continuous laser welder work in the field of auto parts. In addition, continuous welding processing is very suitable for the current manufacturing industry with its extremely high efficiency and stability. The general trend of shifting from manual and semi-automated production mode to intelligence and automation.

The pulse laser welding machine market continues to shrink, but some pulse lasers, especially Nd3+: YAG solid-state lasers, are cheap and simple to use. And for some special materials, it’s also better to use pulse laser welder, so pulse welding will continue to exist for a long time in the future.

Regarding how to choose two laser welding methods, and laser welding machines, pulse welding has low efficiency, high use cost, but low cost, and high single pulse energy; continuous welding has high efficiency, low operating cost but high price. Both have their own advantages and disadvantages, so they are different. The scope of application.

In short, there is no best laser welding method, only the most suitable laser welding machine for customers. Our Changtai laser company strives to provide customers with the best quality and most suitable laser welding machine solution and find the right welding method, contract us for a laser welder suggestion >>
