PURPOSE: An automatic welding machine of T-shaped structure is provided which is autonomously driven along a bonding part of the base metal and forms superior welding beads on the bonding part in welding a T-shaped base metal of large scale structure so as to obtain superior welded joint. CONSTITUTION: The automatic welding machine of T-shaped structure comprises a moving part in which a front carriage(100) and a rear carriage(110) are respectively positioned on both surfaces of a T shaped bonding part(3) of two base metals in such a manner that wheels receiving rotary power from a driving means(101) are installed at the front and rear carriages(100,110) so that the front and rear carriages(100,110) are integrally traveled along the bonding part(3) of the base metals; a coupling unit part(40) for enabling reciprocal coupling and separation of the front and rear carriages(100,110) of the moving part with the bonding part(3) of the base metals being between the front and rear carriages(100,110); a welding part(20) which welds the bonding part(3) of the base metals as moving by being mounted on the front carriage(100) coupled by the coupling unit part(40) and is corrected to the optimum welding position along the position of the bonding part(3) that is changed; and a cooling part(30) in which a front copper shoe(300) and a rear copper shoe(310) are respectively installed at the lower part of the front and rear carriages(100,110) to cool molten metal generated as the bonding part(3) of the base metals is being welded by the welding part(20) in such a manner that the front and rear copper shoes(300,310) are reciprocally correspondingly and cohesively installed on both surfaces of the bonding part(3) of the base metals.
