|
| The ACW® method has various advantages. The big advantages include (1) to (6) below. |
| |
| (1) Only one type of forming material is used! |
| As the material used for the ACW® method has both transmission and absorption properties, two different
materials do not need to be used. Only one type of material is required. |
| |
 |
| |
| (2) Welding with strong bonding property! |
| A molten pool formed in the ACW® method starts growing from the surface of the resin irradiated with laser,
reaches the bonding surface, and starts being welded. In this manner, with
the ACW® method that forms a large molten pool, it is possible to obtain higher
welding strength (tension shear strength) compared to conventional welding
methods. |
| |
 |
| |
| (3) Tolerates larger gap! |
| In the method to weld resin with laser, shrinkage or
warping caused by forming process produces a gap at the bonding portion, resulting
in a welding defect. However, in the welding of nylon 6 through the ACW® method, welding is possible even when a gap (0.2 mm) four times that formed
in standard welding method is present. |
| |
 |
| |
| (4) Laser irradiation can be set in any direction! |
| As the ACW® method uses the same forming material, there is no restriction on the
laser irradiation direction. It is possible to conduct welding from any
direction. |
| |
 |
| |
| (5) Abutting welding is possible! Furthermore,
abutting welding of cylindrical objects, roll forming objects is possible! |
| With the ACW® method, abutting welding is possible. Manufacturing of cylindrical products,
welding of same materials such as roll forming objects, and welding of
pipe-shaped products, which are normally formed through extrusion molding
can be conducted by abutting welding. |
