How to choose a handheld fiber laser welder?
There are many companies in the handheld fiber laser welding equipment supply market. There are some laser manufacturers and a lots of trading companies without laser technical support. How to explain a hand-held fiber laser welding machine from a professional perspective? It’s important to let users know what they want when buying, buy a satisfactory machine and use it without worrying too much about equipment failure. Five Laser hopes to analyze it from the perspective of a manufacturer, so that readers can learn from this article some gains from sharing, to purchasing based on actual needs for welding, find a hand-held optical fiber welding machine that is most suitable for you
I. The choice of laser power
To choose a handheld fiber laser welding machine, the first thing to consider is how many watts of laser power configuration you have to choose. Because this directly determines whether this equipment is capable of your welding work. Different laser power means suitable for welding materials of different thickness. At present, the laser power for handheld fiber laser welder are 500w, 1000w, 1500w, and 2000w. With the development of welding demand, the 500w is gradually decreasing, and 1000w is slowly becoming the major selection. The following is our recommendation the parameters of different laser powers are suitable for different thickness of stainless steel for reference. For example, FLW-1000H (1000w) is suitable for welding of stainless steel with thickness of 0.5~2.5mm
II. The choice of laser source brand
The handheld fiber laser welding machine adopts continuous fiber laser source. As the core component of the equipment, which plays a decisive role in the stability of the machine. At present, the two leading laser brands in China are Raycus and Max ( They developped more than 10,000 watt fiber laser source, such as Raycus has developped 20,000 watts fiber laser source), so their low-power 1000w~2000w will be relatively stable, and the price will be around 500usd higher than other peers for each laser source. At present, there are other optional Chinese brands fiber laser source in the market such as RECI, JPT and GZ brand. Therefore, while considering the purchase cost, you must balance the long-term stability of the equipment.
III. The choice of laser welding head
The welding head is one of the core components of the hand-held fiber laser welding machine. The role of the laser output terminal affects the efficiency and effect of the laser output, and indirectly determines the welding effect. At present, there are about two kinds of welding heads in the market: Single motor welding head (built-in single scanning motor) and Dual-scanning motor welding head (built-in dual scanning motor). Single motor welding head can usually output dot or line laser mode; The dual-scanning motor welding head has built-in X/Y axis dual, In addition to the point-shaped and linear-segment laser modes, it can also form a circle, a triangle, a double triangle working mode, total 6 laser working modes. More laser working modes, especially triangular working mode, there is a lot of improvement in welding quality and strength, which is the advantage of dual-scanning motor welding head
At present, the common handheld laser welding heads in the market mainly include QiLin, Ospri, Raytool, WSX and other brands.

IV. Selection of other important components
A. The current power level of handheld fiber laser welding machine is between 500w and 2000w, so water cooling is very important. The cooling effect or the accuracy of temperature control directly affects the working efficiency of the laser output components. In addition to the cooling of the core continuous fiber laser, the laser IQB output head and the handheld welding head also need water cooling
B. The stability of the control electricity circuit: such as the brand of switching power supply, the use of relays and contactors
C. Nozzle type configuration: usually there are inner corner use, outer corner use, flat surface use, wire feeding use, and cutting use nozzle
D. Software and touch screen function types and ease of use
V. Detection software and multiple protection functions
A. Continuous fiber laser auxiliary detection software, if a failure occurs, the cause of the failure can be quickly detected and quickly eliminated, because the detection software is a powerful assistant
Ｂ．Laser shutter: Used to cut off the light path safely when pause use temporarily, to avoid accidental operation and hurt people
Ｃ．Welding head ground wire protection
Ｄ．Water flow protection function: used to protect the laser and laser output components in the case of abnormal water cooling or insufficient water flow
I hope that the above sharing can be helpful to users who are preparing to buy a handheld fiber laser welding machine. If you have any questions or problems, you can contact the staff of Five Laser at any time. If you have different valuable experiences or opinions on the above sharing, I hope it can be more share, thank you!
