At the heart of any pipeline welding operation is the welding machine. There are various types of welding processes, such as MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), and stick welding. For pipeline welding, SMAW (Shielded Metal Arc Welding) and GTAW (Gas Tungsten Arc Welding) are preferred due to their versatility and effectiveness on thicker materials.
