What is welded 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.
Welded steel pipe in the form of welds are divided into straight seam welded pipe and spiral welded pipe. By production method classification: process classification - arc welded pipe, resistance welded pipe, (high frequency, low frequency) gas welded pipe.
