There is no extraction tool to extract valve seats from cylinder head. What is the correct way to dismantle them to install new ones?

Welding of valve to the valve seat is required in this case
- Cut the old valve from 2 sides to give enough space for welding
- Choose correct welding rods about 2-2.5 mm so no damage done to cylinder head area close to seat
- Weld the valve to the seat
- Knock out welded part by hitting the valve stem by hammer.
