Manufacturing Method of Pressure Sensor and Pressure Sensor |
摘要 |
<p>A manufacturing method of a pressure sensor (1) that includes a pressure detector (20) having a bottomed cylindrical member (21) with a bottom including a thin-wall portion (210) and a strain detecting mechanism provided on one side of the bottom for detecting a strain of the bottom and a pressure-introducing joint (10) for introducing the fluid to be measured into the bottomed cylindrical member (21) is provided. The method includes: first welding for butt-welding an end of the cylindrical portion (211) of the bottomed cylindrical member (21) and an end of the pressure-introducing joint (10); and second welding for welding the pressure-introducing joint (10) in parallel to a first weld bead (51) formed by the first welding.
