The laser of the laser welding machine is a high-intensity light source. Generally, the emitted laser can be considered as no bodily harm when it is inaccessible or invisible. However, the laser welding machine will produce ionizing radiation and stimulated radiation that are harmful to the eyes...

Aluminum is a good conductor of heat and electricity, and its high density of free electrons makes it a good reflector of light. Laser welding of aluminum alloy requires a higher output power in the initial stage to ensure the necessary power density. When the small hole in the weld pool is...

With its energy concentration, high welding efficiency, high processing accuracy, and large weld aspect ratio, laser has become the copper-aluminum welding of power batteries, and even the only technology that can weld electroplated nickel to copper materials. Reasonable selection of welding...

With the renewal and development of consumer electronic products such as mobile phones, tablet computers, and notebooks, a large number of new processes, new materials, and new structures have been applied. Aluminum alloys have the advantages of light weight, high strength, corrosion resistance,...

Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working materials. It has the characteristics of small size and long lifespan, and can use simple injection current to pump its working voltage and current compatible with integrated circuits, so it...

Features of laser deep penetration welding: 1) Large depth-width ratio. The molten metal is formed around the cylindrical high temperature vapor cavity and extends to the workpiece, and the weld becomes deep and narrow. 2) Minimum heat input. Because the temperature in the small hole is very...

Protective gas In the laser welding process, inert gas is often used to protect the molten pool. When some materials are welded, the surface oxidation may not be considered, but the protection may not be considered. However, for most applications, helium, argon, nitrogen and other gases are...

Lens focal length A convex lens is usually used to converge the laser during welding, and a lens with a focal length of 63-254mm is generally used. The focus spot size is proportional to the focal length, the shorter the focal length, the smaller the spot. However, the focal depth increases...

Laser power: Laser welding has a laser energy density threshold. Once this value is reached or exceeded, the penetration depth will be greatly increased, otherwise the penetration depth will be very shallow. Only when the laser power density on the workpiece exceeds the threshold (related to the...

Laser welding can be realized by continuous or pulsed laser beam. The principle of laser welding can be divided into heat conduction welding and laser deep penetration welding. The power density is less than 105 W/cm2 for heat conduction welding. At this time, the penetration depth is shallow...

Laser processing has played a significant role in the volume optimization and quality improvement of high-end electronic products, making the products lighter and thinner and more stable. At present, laser precision welding is mainly used for electronic products like shielding cover, USB...

Water bottles are the necessities of our life, most of which are stainless steel. Stainless steel kettle laser welding machine is a kind of equipment which focuses on the welding of kettles. It has good quality and fast welding speed, and is deeply loved by major kettle manufacturers. But although the equipment is good, it still needs the correct way of use to ensure the durability of the equipment. Next, Riselaser summarizes five points for attention in the use of laser welding machine for stainless steel kettles.

Laser welding is the use of high-energy laser pulses to the material in a small area of local heating, laser radiation energy through the heat conduction to the internal diffusion of the material, the material melted to form a specific melting pool.
