The laser welder machine has transformed the welding industry with its ability to deliver high-intensity light beams that provide concentrated heat sources. This technology enables narrow, deep welds and fast welding speeds, making it a preferred choice for high-volume applications in industries such as automotive and medical. The laser welder machine is a non-contact process, requiring access to the weld zone from only one side, which enhances its versatility and ease of use.
Laser welder machines use focused laser beams to join materials. The intense heat generated by the laser beam allows for precise and efficient welding, producing high-quality welds that often require minimal post-weld processing. This technology is suitable for a variety of materials, including stainless steel, carbon steel, aluminum, and copper.
– Conduction Welds: These are performed at low power, resulting in wide, shallow welds. Conduction welds are ideal for applications requiring minimal penetration.
– Transition/Keyhole Welds: Utilizing medium power density, these welds create deeper welds with a width-to-depth ratio of around 1. They are suitable for applications needing moderate penetration.
– Penetration or Full Keyhole Welds: Achieved with high power, these welds result in deep, narrow welds with a width-to-depth ratio between 3-10. They are perfect for applications requiring maximum penetration and strength.
Laser spot welding is a precise welding process that uses a laser to create a single weld spot to join metals. The high power density of the laser enables rapid melting and solidification of the metal, creating strong and durable welds. This process is ideal for applications requiring small, precise welds, such as in electronics and medical devices.
In laser seam welding, the part to be welded is moved or rotated under the laser focus head, allowing for continuous or overlapping spot welds. Key parameters for seam welding include pulse repetition rate, welding speed, and focused spot diameter. This process is commonly used in applications requiring long, continuous welds, such as in automotive and aerospace industries.
