Handheld Laser Welding Machines

Laser welding of stainless steel locomotive body is the process of laser welding the stainless steel skin and internal framework of the locomotive from the inside out. Unlike traditional welding, it does not allow welding marks and thermal deformation to appear on the outer surface of the skin, but requires high aesthetic appearance, similar to “scar-free stitching”. This welding method is widely used in locomotive manufacturing in developed countries such as Europe, America, and Japan, and has become one of the important technologies in manufacturing new models of high-end locomotives.

Products within the medical industry require the highest levels of precision. It is incredibly important that they meet the highest quality demands. The size of many medical devices and products are continually decreasing. This is where lasers are perfect as they are perfectly suited for creating equally minute weld seams. Even in complicated areas, laser weld spots and seams can easily be generated to provide sterile surfaces with no post-processing.

Electronic parts and components includes electronic components and parts of small machines and instruments, which are often composed of several elements and can be widely used in similar products; It is a general term that often refer to certain components in industries such as electrical appliances, radios, instruments, etc., such as capacitors, transistors, hairsprings, springs, and other sub devices. Laser welding features fast welding speed, large depth to width ratio, small deformation, and high density. It is a welding process that utilizes laser action to melt metal surface instantaneously and thus connects the metal. It belongs to non-contact processing method, and therefore does not produce mechanical extrusion or stress, making it especially in line with the processing requirements of the electronic industry.

Laser welding can find its wide welding and automated integration applications in such segmented fields as platinum rhodium alloy nozzle plates of bushing for producing fiber glass, relays, elevator panels, washing machines, dishwashers, smoke exhaust ventilators, microwave ovens, water cups, refrigeration valves, and solar panels.

For welding metal furniture and electrical appliances, handheld laser welders are usually adopted to weld cabinets such as filing cabinets, safes, bookshelves, explosion-proof cabinets, etc., and electrical appliances such as refrigerators, air conditioners, insulated kettles, hot water kettles, etc., due to the fact that handheld laser welders have the multiple merits, including fast speed, sound and visually pleasing welds, and can greatly save labor costs caused to enterprise users, improve efficiency, and deliver effective and complete solutions. The intelligent operation mode makes welding faster.

Laser welding utilizes high-energy density laser beam as a heat source to irradiate the connection location where a joint will be formed two separated work pieces, causing the separated material to quickly melt and even vaporize after absorbing laser energy, and form a molten pool that in the subsequent cooling process will solidifies, causing the two work pieces to join together. Due to the characteristics of concentrated heating zone that can be precisely controlled, small welding deformation and fast welding speed, laser welding is becoming increasingly popular among automotive suppliers.
