I'd call the process welding. Hint to understanding: two items with the same composition and melting point can melt at differing times if they are not of the same mass. It's about btu's not temp. Copper wire will work and be easier to find than a copper penny. For that matter a red gold solder may also work. The direct weld approach and the red gold solder approach will both require torch control Ie. practice. Most times the seam showing isn't the real problem, It's the excessive excess solder showing. Another hint : the pieces of " solder" are thinner than a sheet of paper and about as big as the period at the end of this sentence. My flame is about the size of this l It's an oxy acte flame so you know the temp. It's a jewelry problem. another realm within the metalsmithing world. Brad
