9-TT WLDN< is the most important @ointing method in 2D/ pipes This

method is known as a heat press6re related process ;7 which the pipe end

material of two pipes are melted together 6nder press6re creating a homogeno6spipe str6ct6re Simple in its idea, the ;6tt f6sion process demands high acc6rac7

to give the final prod6ct ie a 9-TT WLD 2owever, the method is ver7

simple and relia;le
