Welded steel pipes are one of the simplest and most durable methods of joining pipes together. Steel pipes can be welded together simply by MIG (metal inert gas), TIG (tungsten inert gas or SMAW (rod metal arc) welding. Avoid any gaps between the two pipes before welding the two pipes together. When welding, take measures to ensure continuous alignment of the two pipes.
Welded steel pipes in the form of welds are divided into straight welded pipes and spiral welded pipes. Classified by production method: Process classification – arc welded pipe, electric resistance welded pipe, (high frequency, low frequency) gas welded pipe.
