Fasteners
a device that that attaches one thing to another or holds something in place.
Ties
a string and other stuff that draws something close.
Adhesives

Welding
welding melts the pieces themselves
Soldering
soldering surround pieces with a different material
Melt
to change from a solid to a liquid state usually through heat
