Who is correct about the placement and number of plug welds?

In autobody repair, the proper placement and number of plug welds are critical for ensuring structural integrity and safety. Technician B's approach of advising to refer to factory specifications is the correct perspective. Factory specifications provide essential guidelines based on engineering principles and testing, ensuring that repairs meet the manufacturer's safety and performance standards.

Following these specifications helps technicians maintain consistency with the original design and ensures that the vehicle will perform as intended after repairs. Different vehicles may require different specifications for plug weld placement, which emphasizes the importance of consulting the factory documentation.

On the other hand, while Technician A suggests a standard placement of an inch apart, this generalization may not apply universally across all makes and models. Each vehicle can have specific requirements regarding the number and spacing of welds to achieve effective repairs. Therefore, relying on standard measurements without consulting the factory specifications can lead to inadequate welds that compromise the repair's integrity. Thus, adhering to factory specifications is the most reliable approach.
