PURPOSE: A welding pass measuring apparatus is provided to indicate the current welding pass to an operator through temperature distribution displayed in a display unit. CONSTITUTION: A welding pass measuring apparatus comprises first and second temperature measuring sensors(210, 220), third and fourth temperature measuring sensors(310, 320), and a display unit(400). The first and second temperature measuring sensors are installed in one surface of base metal members(M, M') to be welded respectively and the third and fourth temperature measuring sensors are installed in the opposite surfaces of the base metal members respectively. The display unit is connected to the temperature measuring sensors and displays the measured temperature. |
