Tube Welding, Polishing, and Grinding. Welding is a critical process for fabricating useful and durable items from metal tubes. The welding process is used to join the tubing and create a variety of shapes and forms beyond the capabilities of tube bending.

(Welding procedure parameter:The floorboard of all physical terms(as weiding current,arc voltage,welding speed, energy definitions and so on)which are selected to ansure the welding quality when welding is taken is called welding procedure parameter)

Welding involves joining two or more pieces of metal together to form a single piece. Molten metal is generated through an intense heat source, such as oxygen and fuel gas or an electrical arc. Common welding processes using an electrical arc include Shielded Metal Arc Welding, Gas Metal Arc Welding, and Gas Tungsten Arc Welding.

Grinding Process Grinding is a surface finishing operation where very thin layer of material is removed in the form of dust particles. Thickness of material removed is in range of 0.25 to 0.50 mm. Tool used is a abrasive wheel Grinding machine is a power operated machine tool where, the work piece is fed
