Abstract: The present subject matter discloses an apparatus for welding tubes using integrated tungsten inert gas and machine inert gas torches’. More particularly, an apparatus for welding a plurality of tubes utilizes an integrated Tungsten inert gas (TIG) torch (12) and a Machine inert gas (MIG) torch (14) within a single Straight Tube Butt (STBW) Welding machine (STBW). The apparatus features a control unit (20) connected to the power sources of both torches to orchestrate the welding sequence. At least three gas lines (15, 16, 3) are connected to the control unit (20) to manage gas supply for TIG or MIG welding. Each gas line incorporates components for supplying the welding gas according to the selected torch. The apparatus provides the required tube length by employing TIG or MIG welding using single straight tube butt welding (STBW) machine. (FIG. 3)
