General information about Welding

We can obviously know that Welding is the very sculptural process that usually used to connect metals or thermoplastics. A welding ball valve is a ball valve that is produced by such process. This is often done by melting the work pieces and adding a filler material to form a pool of molten material that cools to become a strong connection, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the work pieces to form a bond between them, without melting the work pieces.
