Welding non-standard materials can affect the visual appearance of the weld. The color, texture, and shape of the weld may be different than that of standard materials, due to variations in the chemical composition, melting point, and other properties of the non-standard Material. Additionally, the welding process itself may produce different results when working with non-standard materials. For example, the heat input and cooling rate may be different, which can affect the final microstructure of the weld. It’s important to take into account these variations when welding with non-standard materials to ensure the weld meets the required specifications and safety standards.
