What gas is used with laser welding machine?

The shielding gas will provide favorable conditions for the formation of the weld. When the welded material has surface oxidation, it is necessary to use the shielding gas; when the welded material does not care about the surface oxidation, it is also possible not to use the shielding gas. There are three kinds of maintenance gases used most by laser welding machines, namely helium, argon and nitr

Q What are the safety precautions for laser welding machine?

A Laser welding machines are generally used for tailor welding and repair welding of metal materials. The working principle of laser welding is to use high-energy laser pulses to heat a small area of the material. The high-temperature energy diffuses from the surface of the material to the inside, and forms a specific molten pool after melting. The material in the whole process is in a high temperature state, so how should we use the laser welding machine safely? Precautions for safe use of laser welding machine 1. During the operation, if there is an emergency, such as water leakage or abnormal sound of the laser, it is necessary to immediately press the emergency stop button and quickly cut off the power supply. 2. The external circulating water switch of laser welding must be turned on before operation. Since the laser system adopts water cooling mode and the laser power supply adopts air cooling mode, if the cooling system fails, it is strictly forbidden to start the machine. 3. It is strictly forbidden to touch all circuit components in the machine while working. When the laser welding machine is working, the circuit is in a state of high voltage and strong current. Untrained personnel are prohibited from operating the machine. 4. It is strictly forbidden to use the eyes to scan the laser directly when the laser is working, so as to avoid eye injury. It is forbidden to use external equipment to reflect the laser light when the laser light is working. 5. Do not disassemble any parts of the machine at will, and do not weld when the safety door of the machine is open, and do not aim the laser head at the equipment parts. 6. Do not place flammable and explosive materials in the laser light path or where the laser beam can be irradiated, so as not to cause fire and explosion.

Q What materials can the handheld laser welding process weld?

A The handheld laser welding machine has become a new industrial technology favored by the market due to its advantages of simple operation, high efficiency, and smooth and beautiful weld seam. Handheld laser welding machines are widely used, but many people want to ask what materials the handheld laser welding machine can weld. 1. Stainless steel What materials can the handheld laser welding machine weld The stainless steel of the handheld laser welding machine has a high coefficient of thermal expansion, and it is easy to overheat during welding. When the heat-affected zone is slightly larger, it can cause serious deformation problems. Handheld laser welding machines generate less heat throughout the welding process. In addition, stainless steel has relatively low thermal conductivity, high energy absorption rate and high melting efficiency, and a well-formed weld can be obtained after welding. 2. Carbon steel Ordinary carbon steel can be directly welded by hand-held laser welding, which is comparable to stainless steel welding with a small heat-affected area. However, when welding medium and high carbon steel, the residual temperature is still relatively high, so preheating before welding and heat preservation after welding are required to eliminate stress and avoid cracks. Here, we can say cold welder. Medium to high carbon steels can be slowly welded or repaired with cast iron wire cold welding, and cold welders teach hand-held laser welding to be better at post-weld heat residue. 3. Die steel The handheld laser welding machine can be used to weld various types of die steel, and the welding effect is very good. 4. Aluminum and aluminum alloy Aluminum and aluminum alloys are highly reflective materials and porosity may develop in the weld pool or root during welding. Compared with previous metal materials, aluminum and aluminum alloys have higher requirements on parameters, but as long as proper welding parameters are selected, welds with the same mechanical properties as the base metal can be obtained. 5. Copper and copper alloys Copper has very strong thermal conductivity, and it is easy to produce incomplete penetration and partial incomplete fusion during welding. Typically, during the welding process, the copper material is heated to aid in the welding. Here I am talking about thin copper materials. Because of its energy concentration and fast welding speed, it can be directly welded by hand-held laser welding. The high thermal conductivity of copper has little effect on it. 6. Welding between different materials The handheld laser welding machine can be used between dissimilar metals such as copper-nickel, nickel-titanium, copper-titanium, titanium-molybdenum, brass-copper, and low-carbon steel-copper. , laser welding can be carried out under certain conditions (gas or temperature).

Q What are the limitations of laser welding?

A Laser welding machines are widely used in the welding of thin-walled materials such as stainless steel and carbon steel, such as water tanks, mold machinery, decorative advertisements, kitchen utensils and bathrooms, jewelry, door and window frames, electronic appliances, household items, sheet metal processing, auto parts, etc. Related areas. According to different usage methods, laser welding machines are divided into handheld laser welding machines and desktop laser welding machines. Limitations of handheld laser welding machines 1. High machine cost: Compared with traditional welding equipment, laser welding machines are expensive and require a higher cost, and the more functions the laser welding machine has, the higher the price. 2. High environmental requirements: Sparks may appear when welding with a handheld laser welding machine, and strict safety protection measures must be taken, such as wearing goggles to ensure the safety of the working environment and operators. 3. The operation is difficult: the operation mode of the hand-held laser welding machine is hand-held, and long-term work will cause greater arm pressure. Advantages of handheld laser welding machine 1. The hand-held laser welding machine uses a hand-held welding gun, which overcomes the limitation of the workbench space. There is no limit when welding, and it can meet the welding needs of multi-angle and multi-directional, and complete the position of the workpiece that cannot be welded by automatic welding. Small space, high flexibility. 2. The front end of the welding torch of the handheld laser welding machine is usually equipped with a copper nozzle. During the welding process, the copper nozzle can be next to the workpiece, reducing the weight of the welding torch and increasing the stability of welding. The shape is moved and welded. 3. The hand-held laser welding machine has extremely high precision, the laser beam focusing diameter is small, and the welding process has little impact on the surrounding materials, which avoids the material damage that is easy to occur in the traditional welding process, and can also reduce the follow-up for more fragile materials. process to improve production efficiency. 4. The hand-held laser welding machine has fast welding speed and high welding efficiency. This advantage is particularly prominent in the production of mass products; in addition, the hand-held laser welding machine can also adapt to the automated production line and realize fully automated operations. It can not only guarantee product quality, It can also greatly shorten the product production cycle.
