The term JOIN CLOSELY can be used to describe four different processes: welding, knitting, wedding, and soldering. Welding is a process of joining two or more pieces of metal together by melting them and then fusing them together. Knitting is a process of creating fabric by interlocking loops of yarn or thread. Weddings are ceremonies that join two people in marriage. Soldering is a process of joining two or more pieces of metal together by melting a filler material between them. All four processes involve joining two or more items closely together.
