ALAND Welding

  1. Introduction to stainless steel welding   Welding stainless steel refers to the process of joining stainless steel materials into a whole through heating or pressure. Stainless steel requires special attention when welding due to its high alloy content and unique physical and chemical properties. Common welding methods include TIG (tungsten inert gas welding), suitable for thin wall and precision welding; MIG (melting inert gas welding), suitable for thicker materials; arc welding, suitable for structural welding; and laser welding, suitable for for high-precision welding. During welding, pure argon or mixed gas must be used for protection to prevent oxidation, and parameters such as current, voltage, and welding speed must be strictly controlled. Pre-weld cleaning and post-weld treatment are also very important to prevent pores, cracks and other welding defects and ensure the quality and strength of the weld.   2.
