<p>The present invention relates to a bridge tack member for welding of pipe connection, being placed to face each other in a same line, wherein a protruding rib (5a) of which a welding surface is ring-shaped is arranged along the front end of each inner circumferential surface. In the protruding rib (5a), a pair of pipes (5) having an inclined surface (5b) to be symmetrical to face each other toward the outer circumferential surface can be connected from welding as the protruding rib (5a) has a block structure, being spaced from each other at a predetermined distance, wherein a pair of pipe contact surfaces (11) are arranged to be contacted between the inclined surfaces facing to each other, while the pipes (5) are connected through tack welding. Thus, for connecting a pair of pipes to be welded, as the protruding rib is spaced from each other at a predetermined distance, a bridge tack member having a block structure is arranged, wherein a pair of pipe contact surfaces are arranged between the inclined surfaces facing to each other for the pipes to be connected through the tack welding; thereby, a low-temperature cracking problem generated as a conventional pipe protruding rib is performed through tack welding can be solved, and improving welding quality improvement at the same time.</p> |
