Welding pipes is one of the simplest and most durable ways to join piping together
and steel pipes can simply be welded together with MIG (metal inert gas), TIG (tungsten
inert gas or SMAW (stick metal arc) welding. Before welding two pipes together, avoid
any gaps between the two pipes. While welding, take measures to ensure the continual
alignment of the two pipes.
