Hand-held laser welding machines have risen rapidly in the laser field in recent years. With many advantages such as high efficiency, short training time, environmental protection, less consumables, and high scalability, it has been recognized by the market.
At present, handheld laser welding machines are mainly used in non-standard, fixture-free welding processes such as sheet metal, chassis, water tanks, distribution boxes, cabinets, cabinets, kitchens and bathrooms, stainless steel door and window guardrails.
Compared with traditional processes such as argon arc welding and gas shielded welding, hand-held laser welding machines are used for energy saving (traditional welding machines save about 80% of electric energy), or for thin stainless steel, iron, aluminum and other metal materials. Welding speed, welding quality, follow-up processing (which can greatly reduce the labor cost of polishing and leveling processes) have obvious advantages, so there is a great potential for replacing traditional processes in mass welding.
Hand-held laser welding is a welding method in which a high-energy laser beam is used as a heat source, heated to the surface of the material by radiation, and then melted and condensed by heat conduction, and then connected together to form a metallurgical bond.
Because laser welding has the advantages of high precision, small heat-affected zone, small deformation, and high efficiency, it has a good development prospect. With the continuous development of laser technology and numerical control technology, laser welding has become an advanced processing method in the field of industrial sheet welding.
