In the past we often saw welders using manual welding equipment with spark sputtering, but welding a workpiece with a beautiful weld is not an easy task. Staff must wear insulated shoes, thick gloves and protective masks, holding heavy welding pliers in their hands, and unskilled people often make welding mistakes that affect the use of welded parts.
With the development of the times, laser welding machine has replaced the traditional welding method with a manual torch instead of a fixed optical path. Handheld laser welding machine is the most common model on the market today and is a convenient metal welding equipment that can be used flexibly in various environments.
First, let's look at the working principle of laser welding stainless steel.
1. High voltage makes the xenon lamp emit light, and the YGA crystals mounted together are irradiated by the laser and resonate through the total and semi-reflective diaphragm, then through the beam splitter and optical port into the fiber, and finally the laser is focused on the point.
2. The focal plane power density can reach 10 5 -1013 W/cm2.The handheld laser welding machine works by using the excellent directionality and high power density of the laser beam. Through the optical system, the laser beam is focused on a very small area, and in a very short period of time, a local heat source area with high energy concentration is formed at the weld site, which causes the welded object to melt and the weld spot and seam to be formed intensively.
Laser welding can be performed using continuous or pulsed laser beams. The principles of laser welding can be divided into heat conduction welding and deep melt laser welding. When the power density is less than 104~105 W/cm2, it is thermal conduction welding. When the power density is greater than 105~107 W/cm2, the metal surface is recessed into a "hole" under the action of heat, forming a deep fusion weld.
Why more and more people choose this handheld laser welding machine? I think it is because of the advantages of handheld laser welding machine.
1. Easy to operate: you can start welding without spending a lot of money on training.
2. Fast and efficient, wide range of processing: laser welding machine energy concentration, welding efficient and high-speed, smooth and beautiful weld seam, shorten the subsequent grinding process, high quality weld seam, durable.
3. Welding a wide range of materials: stainless steel plate, iron plate, galvanized plate, aluminum plate and other metal materials.
4. Overcome the limitation of part shape and processing environment: small welding joint, small heat-affected zone: no need to install welding table, small size, flexible processing, fast welding speed, can be used for long-distance operation, no limitation of environmental space.
5. Low maintenance cost. Fiber laser welding machine equipped with portable laser welding head for welding operations, this laser welding system can be used for long-term stability and low cost of replacement parts. If you do not know how to replace, you can contact AccTek direct service, no need to worry about after-sales costs.
6. Cost-effective: handheld laser welding machine can not only perform manual laser welding operations, but also high-precision welding and mold repair through the assembly platform. It is the first choice of economic welding equipment for small manufacturers.
Fiber optic welding machine cleaning machine can do spot welding, butt welding, stack welding, gas-tight welding, etc., high aspect ratio, small weld width, small heat-affected zone, small deformation, fast welding speed, flat and beautiful welds, no or only simple processing after welding, high weld quality, no porosity, precise control, small focus, high positioning accuracy, easy to realize automation.
Industrial applications of handheld laser welder and applicable materials:
Used to weld various stainless steel, titanium, copper, purple copper, vintage red copper, iron bars, low carbon steel and other metal materials. Suitable for home appliances and stainless steel doors and windows industry, photoelectric communication, medical, electronics, copper and aluminum parts and small welding industry.
Handheld laser welding machine is a widely used model in today's market, and its economy and durability are recognized by the public. Therefore, the price issue has been the focus of attention. The current market price of fiber laser welding machine is relatively high, but it is easy to operate, convenient and easy to use, and is a versatile device for welders. In the long run, the benefits that laser welding machines can bring are much higher than its cost.
