Title:
PRESSURE SENSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/089724
Kind Code:
A1
Abstract:
A pressure sensing device for detecting, by means of a pressure detecting section (2), the pressure of a fluid introduced through a joint (1) into a cap member (21) ensures reliable joining of the joint (1) and the cap member (21), and simplification of the production process so as to reduce intermediate storage of goods in process.
A washer-like clad member (3) is disposed between a base portion (11) of the joint (1), which is made of brass, and the cap member (21), which is made of stainless steel. The clad member (3) has a first layer (31) made of stainless steel and facing the cap member (21), and a second layer (32) made of oxygen-free copper and facing the base portion (11). The entire periphery of the joining portion of the first layer (31) and the cap member (21) is welded by laser, resulting in formation of a welding mark (7). The entire periphery of the joining portion of the second layer (32) and the base portion (11) is welded by laser, resulting in formation of a welding mark (8). A release mark (8a) is formed to attenuate the output of the laser light while releasing the laser light towards the base portion (11)-side.
