In laser welding, "gas" cannot be ignored
Laser welding is mainly aimed at welding thin materials and precision parts.
In laser welding, "gas" cannot be ignored. This "gas" refers to the protective gas, and its selection directly affects the quality, efficiency, and cost of welding production.
Laser welding technology plays a crucial role in modern industry. In the process of achieving high-quality welding, the use of protective gases such as nitrogen and argon, like the hood of a car, provides a critical barrier for the process.
Isolation of harmful gases: The function of nitrogen and argon is to isolate oxygen, nitrogen, and hydrogen in the air, to prevent oxidation of the weld seam during the welding process, and to prevent the formation of pores, ensuring the integrity of the weld seam.
Protecting the focusing lens: The focusing lens of modern welding machines requires additional protection to prevent sputtering damage. Especially in high-power laser welding, this protection is particularly important because strong jets may pose a threat to the lens. Howweld team use nitrogen gas.
Disperse plasma: During laser welding, the formation of plasma clouds can affect the penetration and efficiency of the laser. The protective gas can effectively remove these plasmas by blowing, enhancing the absorption of laser energy by the molten pool.
When choosing a protective gas, helium can effectively suppress the generation of metal vapor due to its low ionization degree, but the cost is relatively high. In contrast, nitrogen and argon have higher cost-effectiveness and demonstrate stable protective effects in practical applications, making them widely used.
Balance between economy and practicality: Between economic considerations and practical effects, nitrogen and argon are often preferred as they not only provide good protection but also meet the needs of industrial production in most cases. Our brand is HWLAZER which used for laser system promotion.
In general, the application of nitrogen and argon in laser welding is not only related to the accuracy of the process, but also to the economy and efficiency, and is a key element in achieving high-quality welding processes.
