How do threaded joints differ from welded joints?

• A. Threaded joints are fused together using heat
• B. Welded joints utilize special fittings
• C. Threaded joints are mechanically joined using threaded fittings
• D. Welded joints can be easily disassembled

Answer: (C)

Threaded joints are characterized by their method of joining components through the use of threaded fittings, which create a mechanical bond. This mechanical connection is achieved by screwing the threads of one fitting into those of another, allowing for a secure connection without the need for soldering, welding, or adhesives. This method provides versatility in installation, allowing for easier adjustments, repairs, or replacements compared to welded joints. Unlike threaded joints, welded joints involve the fusion of materials at their interfaces through the application of heat. This process creates a permanent bond that generally cannot be easily disassembled once completed. While welded joints are often considered stronger in terms of pressure capability and longevity, they lack the convenience of being disassembled and reassembled as easily as threaded joints can. Additionally, the use of special fittings is generally more associated with welded joints, which require specific methods and skills to execute properly. Thus, threaded joints are distinct due to their mechanical joining technique, which makes them practical for applications requiring frequent modifications.
