2. What are the key factors to consider when selecting the appropriate welding process for a particular application in boilermaking?

Material Thickness:

• SMAW and FCAW are suitable for thicker materials.
• GMAW and GTAW are better for thinner materials.

Joint Design:

• SMAW and FCAW are suitable for various joint designs.
• GMAW and GTAW are better for precise and complex joints.

Weld Quality:

• GTAW provides the highest quality welds.
• GMAW and FCAW offer good weld quality for industrial applications.
• SMAW produces welds with lower strength and ductility compared to other methods.

Cost and Efficiency:

• SMAW and FCAW are typically more cost-effective but less efficient.
• GMAW and GTAW are more efficient but can be more expensive.

3. How do you ensure that your welds meet the required standards and specifications for boilermaking?

To ensure weld quality, I follow these steps:

• Properly preparing joint surfaces by cleaning and beveling.
