| Method | Access | Strength | Equipment Cost | Speed | Best Use Case | |--------|--------|----------|----------------|-------|----------------| | | Single side | High | Low to medium | Medium | Field repair, mixed thicknesses | | Resistance spot weld | Both sides | Medium | Very high (specialized machine) | Very fast | Automotive production lines | | Rivet / bolt | Both sides (usually) | Medium (shear) | Low | Slow | Non-permanent joints | | Continuous fillet weld | One or both sides | Very high | Low | Slow | Structural, leak-tight joints |

Once the hole is formed, the welder deposits electrode material into the opening, creating a molten pool. puddle welds

The temperature of the molten pool can be calculated using the following equation: | Method | Access | Strength | Equipment

Puddle welds, also known as "puddle welds" or "spot welds," are a type of welding technique used to join two metal pieces together. This method involves creating a small pool (or puddle) of molten metal to fuse the two parts. Proper geometry is critical

Proper geometry is critical. While specific codes vary (e.g., AWS D1.1 for structural steel, AWS D8.8 for automotive), general rules include:

The weld penetration can be calculated using the following equation:

The process involves the following steps:
