What is black  square&rectangular steel pipe?.

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.
