As a trend in the consumer market for furniture, stainless steel appliances are growing in popularity.
Homeowners want to create the look of a gourmet kitchen with appliances that have metallic features, including refrigerators and ovens.
To meet this demand for stainless steel kitchen appliances, manufacturers turn to laser welding, which allows them to weld materials together with a laser for a more precise and seamless process.
Household appliances liberate people from heavy, trivial and time-consuming domestic work, create a more comfortable and beautiful life and work environment for human beings, and provide rich and colorful cultural and entertainment conditions, which has become a necessity of modern family life.
Household appliances such as refrigerators, washing machines, air-conditioning alloy boxes, television metal shells, other metal accessories are mainly made of thin carbon steel, stainless steel, galvanized sheet materials, which have high requirements for lightweight, dimensional accuracy and appearance aesthetics of products.
As a household necessities, the market space of kitchenware and bathroom is extremely huge. With the improvement of daily consumption level, the structure of kitchenware and bathroom products has gradually evolved from meeting the functional requirements to the direction of beauty, fashion, environmental protection and low energy consumption, and the use of materials and processing technology are also constantly upgrading.
A large number of metal panels such as stainless steel are used for smoking machines, gas appliances, cooking ranges, disinfecting cabinets, shower showers and water basins, etc., which requires high lightweight, dimensional accuracy and aesthetic appearance of products.
The high peak energy and non-contact processing form of Lasermach laser Welding machine is particularly suitable for sheet metal processing, which can achieve high processing speed, high size accuracy, no deformation of parts, and low production cost; compared with the traditional argon arc welding process, the laser welding process has the advantages of fast welding speed, small deformation of workpiece, smooth and beautiful weld, and no need for secondary processing.
Compared with arc welding, the kitchenware laser welding machine saves about 80%-90% of electric energy, and the processing cost can be reduced by about 30%. It can weld dissimilar steels and dissimilar metals, and can easily complete mechanization and automation. Fast speed, small deformation, small heat-affected zone, high aspect ratio. The welding seam is beautiful, smooth, without air holes, no need to handle or simple treatment after welding, small spotlight, no pollution, high-precision positioning, the handheld laser welding machine can be used for small open parts and precise welding.
Because of the extremely low heat input during laser welding of kitchenware, the amount of deformation after welding is very small, and a very beautiful welding surface can be obtained. There are few subsequent welding treatments. Hand-held laser welding machines can greatly reduce or eliminate huge polishing and leveling, resulting in a very low labor cost of the process.
The traditional welding method of welding stainless steel sinks is not only barely satisfactory in appearance, but often leaks at the weld seam. The deformation is large, the dark colouring is wide and the subsequent post-processing process of grinding, polishing and cleaning is complicated and expensive.
Using a wobble laser welding machine to weld stainless steel sinks not only improves welding efficiency and appearance but also greatly reduces the scrap rate of the product. The laser welded stainless steel sink has beautiful welds and will not leak. No filler or solder, no lead pollution. And the laser welding process will not cause the substrate to change. The weld bead is smooth and flat, easy to clean, firm, and hygienic.
The heat input during laser welding is extremely low, the deformation after welding is very small, and a very beautiful welding surface effect can be obtained, so it barely needs any subsequent post-processing of grinding, cleaning or polishing. Laser welding of the stainless steel sink WILL greatly reduce or remove the huge polishing, grinding and leveling labor in the process. This is especially true in today’s rising labor costs.
Early water sinks were generally welded by argon arc welding, it is easily deformed and the subsequent treatment process was complicated. When receiving related customer needs, Lasermach took it seriously. We have developed a continuous laser welding machine based on our "WOBBLE-CUBE" for customers to weld various shapes of sinks, making customers’ products extremely competitive.
The high peak energy and non-contact processing form of Wobble-3 Series laser machines are particularly suitable for sheet metal processing, which can achieve high processing speed, high size accuracy, no deformation of parts, and low production cost.
Compared with the traditional argon arc welding process, the laser welding process has the advantages of fast welding speed, small deformation of workpiece, smooth and beautiful weld, and no need for secondary processing.
Laser welding is an efficient and precise welding method using high energy density laser beam as heat source. The laser radiation heats the workpiece surface, the surface heat diffuses to the interior through the heat conduction, by controlling the laser pulse width, energy, peak power and repetition frequency and other parameters, the workpiece melts, forms a specific melting pool. Compared with the traditional welding, fiber laser welder has a higher intensity, high-quality laser welding machine can provide good basic guarantee for the kitchen electricity industry processing.
Workpiece welding in the kitchen appliance industry is mostly stainless steel sheets with a thickness of ±1 mm, and mainly tailor-welded and fillet welding. Compared with traditional argon arc welding, laser welding speed is increased by 5-10 times, the welding quality is stable, and the heat affected area is smaller. General products can reduce the grinding process and save part of the labor and equipment grinding costs.
As an important application in laser processing, fiber laser welding machine has the irreplaceable advantages of traditional welding. It is already widely used in kitchen appliances, household appliances, precision cabinets, precision sheet metal products, elevators and other industries.
