Abstract

PURPOSE: To prevent the production of defective joints and improve reliability of pressure-welded joints by detecting the pressure compressing rates and pressing time of steel material heating areas and abnormalities such as slips of steel material gripping parts and abnormal decrease of power source and others, displaying these automatically and interrupting the process in the event of the occurrence of a significant abnormal state.
CONSTITUTION: The chart is the automatic gas pressure welding process chart containing the arrive of the amount of compression steel material heating areas at the intended value in a part of the process. The width of the heating area of the steel material is expanded by subsequently expanding the amplitude of the reciprocating motion of a burner in the axial direction of the steel material. In the 2nd, 7th and 8th processes, hydraulic pumps operate to maintain the preset pressures but in the intermediate 3rd to 6th processes, the pumps stop and therefore the pressure gradually decreases with shrinkage of the steel material. In the pressing processes 2, 7, 8, shrinkage margins d1, d3, d4 are respectively set to control the pressing quantity.
