Understanding ER 316 LSi Welding

ER 316 LSi is a filler wire specifically designed for welding austenitic stainless steels, particularly those subjected to corrosive environments. It's composed of nickel, chromium, and molybdenum, making it ideal for applications that require improved resistance to pitting and crevice corrosion. The added silicon in the composition helps improve wetting and reduces the formation of slag during welding, ensuring a smoother finish.

Key Techniques for Successful ER 316 LSi Welding

To master ER 316 LSi welding, it’s crucial to follow specific techniques that enhance weld quality. Here are some effective methods:

1. Proper Equipment Setup

   • Ensure your welding machine is calibrated correctly for the specific thickness and type of stainless steel you will be working with. Use a mixture of argon and helium as shielding gases for optimal results when welding with ER 316 LSi.

2. Cleanliness is Essential

   • Before starting the welding process, make sure the base metal and filler wire are clean and free from oil, dirt, and oxidation. This is vital for preventing contamination and achieving stronger welds.

3. Control Heat Input

   • Proper control of heat input is essential to avoid warping and maintain the metallurgical properties of the base material. This can be achieved by selecting appropriate voltage and travel speed settings for your welding machine.
