Gas Welding of Copper Sheets
Gas welding is a commonly used process for joining metal sheets, including copper sheets. The process involves the use of a fuel gas, such as acetylene, and an oxidizing gas, such as oxygen, to create a flame that melts the edges of the metal sheets. The molten edges are then fused together to form a strong bond.
Neutral Flame
A neutral flame is achieved by adjusting the ratio of the fuel gas to the oxidizing gas to achieve a balanced mixture. In the case of gas welding copper sheets, a neutral flame is typically used. This flame has a lower temperature and is less likely to cause oxidation or other defects in the welded joint.
Defective Weld
In the given scenario, a neutral flame was used during the gas welding of the copper sheets. However, the resulting weld was found to be defective. The exact nature of the defect is not specified in the question. It could be a lack of fusion, incomplete penetration, or some other issue.
Rewelding with an Oxidizing Flame
To correct the defective weld, the copper sheets were rewelded using an oxidizing flame. An oxidizing flame has a higher temperature and an excess of oxygen compared to a neutral flame. This type of flame is more suitable for certain applications, such as welding steel or cutting metal.
Consumption of Oxygen
The question asks for the likely consumption of oxygen in liters when using an oxidizing flame. Since the fuel gas used is acetylene, the consumption of acetylene is already given as 8 liters.
When using an oxidizing flame, the consumption of oxygen is typically higher compared to a neutral flame. However, the exact ratio of acetylene to oxygen is not mentioned in the question. Therefore, we cannot determine the exact consumption of oxygen.
Conclusion
In conclusion, the likely consumption of oxygen in liters when using an oxidizing flame for rewelding the copper sheets cannot be determined from the information provided in the question. The correct answer would be option 'C' if the consumption of oxygen was given or could be calculated based on the acetylene consumption and the known ratio of acetylene to oxygen.
