Therefore, certain laser power and a certain thickness of a particular material have a suitable welding speed range, and in which the maximum depth of melt can be obtained at the corresponding speed value. Beam spot size is one of the most important variables in laser welding, as it determines the power density. In mass production tests, laser remote welding has reduced the time by 80% compared to conventional resistance welding. Laser fusion welding is a welding method that uses a laser as the heat source to melt the base material of two plate parts at the corner of each plate part to form a liquid metal, and after it cools, a reliable connection is formed.
Thanks to quick programming and simple operation, the TRUMPF arc welding cell is ideal for getting started with automated welding. You benefit from higher productivity and quality compared to conventional manual welding. However, in some industries, the surface needs to be polished after welding, and there will be dents after laser pulse welding, and the amount of polishing will increase, which increases the processing cycle and production costs.
Based on this traditional approach to laser technology, a standard laser cutting head cannot be used for welding, and a laser welding head cannot meet the cutting speeds and quality demanded in most industrial applications. In some laser machine designs, an exchange of heads is possible if the user wants to change between cutting and welding operations. Some laser engineers deal with the challenge by installing two heads, a cutting and a welding head, simultaneously in one machine. The handheld laser welding machines for metals, equipped either with an independently developed wobble welding head or a common welding head, greatly improving the joint strength and quality of welding and obtaining better weld formability.
Germany’s Audi, Mercedes-Benz, Volkswagen, Sweden’s Volvo and other European car manufacturers as early as the 1980s, the first to use laser welding roof, body, side frames and other sheet metal welding. With the continuous development of science and technology, many industrial technologies on the special requirements of materials, the application of smelting and casting methods of manufacturing materials can no longer meet the needs. Under certain laser power and welding speed conditions, the focal point is in the best position when the depth of melt is maximum.
And its own precision advantages will also be applied in more precision instrument manufacturing industries, thereby continuously benefiting the development of mankind and society. As a result, it itself is mainly used in high-tech fields, and in the future as people’s understanding and mastery of this technology continue to deepen, it will inevitably be applied to more industries and fields. So the factory should produce products with enough beauty and delicacy to improve competitiveness. In a certain range, as the flow of protective gas increases, the tendency to suppress the plasma increases, thus increasing the melt depth, but increases to a certain range that tends to smooth out. protection of the focusing lens from metal vapor contamination and sputtering of liquid molten droplets.
