1. Describe the different welding processes you are familiar with and their applications.

• Shielded Metal Arc Welding (SMAW): Used for welding carbon steel and low-alloy steels in various thicknesses and applications. It is commonly known as stick welding.
• Gas Metal Arc Welding (GMAW): Also known as Metal Inert Gas (MIG) welding, it is used for welding thin metals and is commonly used in automotive and manufacturing industries.
• Gas Tungsten Arc Welding (GTAW): Also known as Tungsten Inert Gas (TIG) welding, it is used for welding stainless steel, aluminum, and other non-ferrous metals, providing high-quality welds.
• Flux-Cored Arc Welding (FCAW): Similar to MIG welding, it uses a flux-filled wire as the electrode, producing welds with less spatter and higher deposition rates.
• Submerged Arc Welding (SAW): Used for welding heavy plates and pipes, it involves a continuous feed of granular flux over the weld area, protecting the weld from the atmosphere and producing high-quality welds.

2. Explain the factors that affect the quality of a welded joint.

3. What are the different types of welding defects and how can they be prevented?

• Porosity: Gas bubbles trapped in the weld metal, caused by moisture or impurities. Prevention: Ensure clean base metal, dry shielding gas, and proper welding technique.
• Lack of Fusion: Incomplete joining of base metals, caused by insufficient heat input or poor joint fit-up. Prevention: Increase welding heat, prepare joints properly, and select appropriate welding process.
• Undercut: Grooves formed along the edges of the weld, caused by excessive heat input or improper welding angle. Prevention: Reduce heat input, maintain proper welding speed, and use the correct torch angle.
• Cracking: Breaks in the weld metal or base metal, caused by excessive stress, lack of ductility, or improper preheating. Prevention: Use proper welding procedures, preheat the base metal when necessary, and reduce stress on the weld.
• Distortion: Warping or bending of the base metal due to welding heat. Prevention: Use proper fixturing, sequence welding to minimize heat buildup, and apply countermeasures such as peening or shrinking.

4. How do you measure and interpret weld quality?

• Visual Inspection: Examination of the weld surface for defects, proper profile, and adherence to specifications.
