AUTOMOBILE FRAME |
摘要 |
<p>For the purpose of obtaining an automobile frame component excelling in stiffness, an automobile frame component 1 includes a closed section constituted by welding a flange portion 3a of a frame component 3 having a substantially hat-like sectional shape to a panel part 5 disposed facing the flange portion 3a, wherein when a welding position coordinate is represented in a coordinate system in which an end of a contact position between the flange portion 3a and the panel part 5 is assumed as 0, and a flange outer end side of the flange portion 3a is assumed as negative (-) whereas a vertical wall side in the substantially hat-like shape is assumed as positive (+), and when a radius of a circular arc-like portion 3c connecting a vertical wall portion 3b and the flange portion 3a in the substantially hat-like shape is denoted as R (mm), and a weldable gap amount is denoted as a (mm), a welding position X represented by the following formula is continuously welded using a one-side welding method:</p> |
