PIPING CONNECTION PARTIAL WELDING METHOD

摘要

PURPOSE: A method for welding a pipe connection part is provided to obtain high welding quality and to reduce manufacturing time by connecting pipes with a gas tungsten arc welding method. CONSTITUTION: A method for welding a pipe connection part is as follows: a step of manufacturing a position guiding unit detachably mounted on the pipe connection part (S100); a step of horizontally leveling the pipes by mounting the position guiding unit on the pipe connection part (S200); a step of removing the position guiding unit after the pipes are fixed by a fixing unit (S300); and a step of welding the pipes (S400). [Reference numerals] (S100) Step of manufacturing a position guiding unit; (S200) Step of horizontally leveling the pipes; (S300) Step of fixing the pipes; (S400) Step of welding the pipes
