Q1: What are the main functions of laser letter welding machine?
A1: It is mainly used for welding metal advertising letters in order to substitute the traditional argon arc welding and tin soldering.
Q2: What are the advantages of laser welding?
A2: The laser welding has no requirements for technicians. It makes users quick start, no deformation once welded and it can be in use directly without need of grinding burr.
Q3: How many models of laser letter welding machines do you have?
A3: At present, the letter welding machines are divided into two kinds by powers, respectively, 300W and 500W, and by functions there are two kinds as well, respectively, common type and double-light path. The common type is mainly designed for small letters while the double-light path, based on the common type, is added a 5 meters of conduction fiber. Hence it will use the common light path when welding small letters, but use the fiber laser welding head when it welding big letters or the parts the common type can’t.
Q4: What are the consumables for the laser letter welding machine?
A4: The laser letter welding machine have no much consumables, it mainly requires electricity which is around 3~5 degrees each hour, then it is the xenon laser lamp which has lifespan of 8 million times in use that is to say approximately 5 hours every day and around 6~8 months to change a new one, however, if you don’t use that much, 1~2 years for a replacement.
Q5: Does the laser letter welding machine require computer? And does it have higher requirements for operators?
A5: The laser letter welding machine doesn’t need computer; it has a control screen on which you just need to set three parameters: the first is CUR current which is for the power size of laser; the second is Wid pulse width which is the time the laser staying on materials; the third is Fre welding frequency that stands for the welding speed. It has no requirements for personnel, just a simple training then can start working.
Q6: Is the laser letter welding machine harmful to human?
A6: The laser letter welding machine adopts the laser wavelength at 1064nm which only affects metals and that is why the machine is only used for welding metals. It does not product radiation to human, but certainly the laser focus point generates heat and make sure the focus nothing touching human. During welding, the CCD screen will indicate the laser position so that to avoid touching human’s hand.
Q7: What materials can the laser welding machine weld?
A7: The machine is mainly suitable for advertising designs and it can weld the materials mainly the stainless, iron sheet, galvanized plate, copper sheet as well as aluminum or other metals. But for users welding more aluminum and coppers, we suggest you choose the laser letter machines at 400W or above.
Q8: What are the differences of your letter welding machines with other brands on market?
A8: On the market, at present, the other brand letter welding machines generally adopts adjustable pressure of power supply, but we adopt adjustable current of power supply which made by ourselves. The biggest difference is that our power supply of current adjustment gives much higher peak value of laser than that of pressure adjustment, for which it is visible from welding aluminum sheet, this is because the aluminum requires very high peak value to be welded together. However, some manufacturers removed the CCD configuration in order to save costs, yet the CCD is useful in actual use. Especially on corner welding, if there is no CCD observation, it could be very difficult to weld. We equipped CCD configuration as well, and it makes easy and fast to observe welding points.
The double-light path machine is matured machine designed and developed by our company after several times of modification. Currently, the double-light path machine is successfully applied to welding middle sized letters (50-150cm), and it uses a 5-meter fiber imported from Germany.
Q9: Working Efficiency of Laser Letter Welding Machine
A9: Once using well of the laser letter welding machine, one machine is equal to 3~5 workers using traditional tin soldering, and for new users, it is equal 1~2 tin soldering workers.
Q10: How is the maintenance of laser letter welding machine?
A10: For entire machine, 2-year warranty except consumables (Its consumables are mainly the xenon lamp which is replaced once a year).
