| 摘要 |
The present invention relates to a laser processing apparatus to manufacture a membrane module, comprising: a first welding unit to enable flow path materials on a penetration side to be attached to each other by laser welding a predetermined welding portion of one flow path material on a penetration side; and another flow path material on a penetration side stacked on a lower portion of the flow path material on a penetration side of a flow path material unit on a penetration side wherein at least a pair of flow path materials on a penetration side are stacked to be formed. According to the present invention, by laser welding flow path materials on a penetration side, the number and area of the welding portion is able to be reduced. As such, a dead space of the flow path materials on a penetration path generated due to welding is able to be minimized to improve an ability of penetration fluid transfer of the flow materials on a penetration side. |
