Oxidizing flame is typically used to weld metals such as brass and copper. Here are the steps:

1. Safety First: Always wear protective gear, including gloves and a welding helmet. Ensure your work area is well-ventilated.

2. Prepare the Metals: Clean the surfaces of the metals to be welded. This removes any impurities that could interfere with the welding process.

3. Set Up the Torch: Connect the torch to the oxygen and fuel gas cylinders. Adjust the regulators to the correct pressures.

4. Light the Torch: Open the fuel gas valve slightly and ignite the gas at the torch tip. Then, slowly open the oxygen valve until you achieve an oxidizing flame. This is characterized by a bright, pointed inner cone.

5. Weld the Metals: Hold the torch at an angle to the joint to be welded. Move the flame along the joint, heating the metal until it begins to melt. Add filler rod to the joint as needed.

6. Cool Down: Allow the welded metals to cool naturally. Rapid cooling could cause the weld to crack.

7. Inspect the Weld: Check the weld for any defects. If necessary, rework the weld until it meets the required standards.

Remember, welding should only be performed by trained individuals, as it can be dangerous if not done correctly.
