What are the 3 types of wires for SAW?

  1. Copper, Aluminum, and Lead

  2. Low, Medium, and High Carbon Content

  3. Low, Medium, and High Manganese Content

  4. Stainless, Galvanized, and Alloy

The correct answer is: Low, Medium, and High Manganese Content

The three types of wires for submerged arc welding (SAW) are low, medium, and high manganese content wires. This is because manganese promotes molten metal fluidity and increases weld penetration. Option A, copper, aluminum, and lead, are not typically used in SAW welding. Option B, low, medium, and high carbon content, refers to the carbon content of steel, not the types of wires. Option D, stainless, galvanized, and alloy, are also not typically used in SAW welding.
