I will argue that this issue is extremely relevant, especially in low voltage and low resistance measurements. You are correct in your position if the entire junction is in thermal stability. If however, the junction is exposed to a sudden change in temperature, air drafts being the most

All this talk about thermal EMFs may not be particularly relevant. Solder is used in connections between two metallic objects, like wire and a terminal. The thermal EMFs between a soldered copper wire and copper terminal have exactly equal and opposite values between the solder and the metals. I
