Fillet Weld Data
ข้อมูลรอยเชื่อมพอก — กำลังลวดเชื่อม ขนาดต่ำสุด/สูงสุด และกำลังรับแรงต่อความยาว
Reference values behind the Beam Weld Connection calculator. Allowable shear on the effective throat (ASD) = 0.30 FEXX.
Electrode strength
| Electrode | FEXX (ksi) | FEXX (ksc) | Allowable shear Fs = 0.30 FEXX (ksc) |
|---|---|---|---|
| E60XX | 60 | 4,218 | 1,266 |
| E70XX | 70 | 4,921 | 1,476 |
| E80XX | 80 | 5,625 | 1,687 |
Minimum fillet weld size
| Material thickness t | (in) | a_min |
|---|---|---|
| t ≤ 6 mm | ≤ 1/4" | 3 mm (1/8") |
| 6 < t ≤ 13 mm | 1/4" – 1/2" | 5 mm (3/16") |
| 13 < t ≤ 19 mm | 1/2" – 3/4" | 6 mm (1/4") |
| t > 19 mm | > 3/4" | 8 mm (5/16") |
Maximum fillet weld size (along edges)
t < 6 mm (1/4"): a_max = t
t ≥ 6 mm: a_max = t − 1.5 mm (t − 1/16")
Unless the weld is specifically designated on the drawings to be built out to full throat.
Fillet weld capacity per cm (kg/cm)
q = 0.707 × a × Fs — one equal-leg fillet weld, per centimetre of length.
| Leg a (mm) | E60XX | E70XX | E80XX | Fs = 1,200 ksc |
|---|---|---|---|---|
| 3 | 269 | 313 | 358 | 255 |
| 4 | 358 | 417 | 477 | 339 |
| 5 | 448 | 522 | 596 | 424 |
| 6 | 537 | 626 | 716 | 509 |
| 8 | 716 | 835 | 954 | 679 |
| 10 | 895 | 1,044 | 1,193 | 848 |
| 12 | 1,074 | 1,252 | 1,431 | 1,018 |
Base-metal shear rupture at the fusion face may govern for thin plates — check it separately. Verify limits against the code edition required by the project.
