Manufacturing method of flow path member, flow path member, liquid discharging head, and liquid discharging apparatus
First Claim
1. A manufacturing method of a flow path member which includes a flow path between a first member and a second member which are stacked together, the method comprising:
- a first step of welding the first member and the second member to each other at a first welding portion in a state in which pressure is applied in a stacking direction to the first member and the second member which are stacked to be in contact with each other; and
a second step of welding the first member and the second member to each other at a second welding portion of a different position from the first welding portion in a state in which a pressure is applied in the stacking direction to the first member and the second member,wherein in the second step, the pressure which is applied to the second welding portion is greater than the pressure which is applied to the second welding portion in the first step, andwherein in the first step, the pressure which is applied to the second welding portion increases as the pressure which is applied to the first welding portion decreases in a state in which a shape of a main body of the first member and a shape of a main body of the second member are maintained.

Abstract
A manufacturing method of a flow path member which includes a flow path between first and second members which are stacked together includes a first step of welding the first and second members to each other at a first welding portion in a state in which a pressure is applied in a stacking direction to the first and second members which are stacked to be in contact with each other, and a second step of welding the first and second members to each other in a state in which a greater pressure is applied in the stacking direction to the first and second members at a second welding portion of a different position from the first welding portion.
