Thanks about the texture. Most metals used for welding melt pretty high therefore an O/A setup is recommended. There are some solders that melt lower but the problem is that once the piece gets hot most of the solder would flow and you could not build up. Brazing rod melts lower than steel but higher than solders. There is also phos-copper rod that melts pretty low but again it is almost impossible to build up.
