Bore welding machine FAQ

Q1: What is bore welding machine?

A1: Bore welding machine is a welding method employed to weld large diameter pipes and fittings in a bore pattern. It is used to create grooves or bores in the walls of pipes or other cylindrical objects. These grooves may be used for various purposes, such as to weld multiple pipes together, to create tapered sections for connecting to other components, or to reduce the weight of the pipe.

Q2: What types of machines are used for bore welding?

A2: Several machines are used for bore welding, including tunnel boring machines (TBMs) that directly bore and weld the pipe sections as they are installed. Pipe boring machines can create cylindrical cavities or bores within a solid material without using or relying on any external material or support. Pip Bore machines are used to make precise horizontal or vertical holes in the alignment of existing pipes. Conventional welding machines can also be used to weld the sections of the bore.

Q3: How does a bore welding machine work?
