What percentage of strength do equipment welds typically achieve compared to manufacturers during compression spot welding?

Equipment welds in the context of compression spot welding are known to achieve a significant amount of strength compared to that specified by manufacturers. When properly executed, these welds can reach approximately 70-80% of the intended strength. This range reflects the effectiveness of the welds generated by the equipment while also acknowledging that factors like machine calibration, operator skill, and material conditions can influence the final strength of the welds.

While the higher percentages suggest optimal performance and exceptionally well-maintained equipment, achieving strengths in the range of 80-90% or even 90-100% is often unrealistic for equipment welds due to these variables. Therefore, the 70-80% range is a practical benchmark in assessing the expected strength of compression spot welds conducted with standard equipment under normal operating conditions.
