Abstract
PURPOSE: To form good penetration shapes be formed through full position one-side welding by forming the backing means comprising holding a consumable backing material with the flat part of a backing strip on the upper half circumference of the tack-welded, and forming the backing means backing the broad groove face of the backing strip to the lower half circumference.
CONSTITUTION: Beforehand, a consumable backing material 4 and a strip-form- copper-made backing strip 3 are disposed on the back side of the groove portions of the pipes 1, 1' to be welded which are fixed in a tack-welded state. A consumable backing material 4 is disposed in the upper half-circumferencial portion of the pipes to be welded 1, 1', in the upper half portion from the point P1 between 9 o'clockW 8 o'clock in clock scale via the point P3 of 12 o'clock to the P5 point between 3 o'clock to 4 o'clock. The consumable backing material 4 is supported by the backing strip 3 but in the resion of 9 o'clockW12 o'clockW3 o'clock, it is supported by the flat backing strip portion 3a having no grooves. The lower half-circumferential portion than P1, P5 is supported by the backing strip portion 3B having a broad groove 5 whose groove width is several to several tens times the groove depth. In this state, full position one-side welding is accomplished from the side opposing to the backing means through the pipes to be welded.
