AI Weld Designer

Weld connection design with v7.0 AI capacity calculation, optimal sizing, and AWS compliance verification.

v7.0 Enhancements¶

? AI weld sizing (minimum size for capacity)
? Real-time capacity (instant load vs capacity)
? AWS compliance (automatic code checking)
? Cost optimization (minimize weld metal)
? 3D weld preview (visualize connection)

AI Weld Sizing¶

Connection: Weld plate to embedded bars
Load: 12 kips shear, 5 kips tension

AI calculates:
Shear capacity per inch: 0.928 kips/sixteenth
Required: 12 / 0.928 = 13 sixteenths
Minimum size: 13/16" ? Round to 7/8" ?

Tension capacity: (additional check)
Required: 5 kips tension
Capacity: Adequate with 7/8" weld ?

AI recommends: 7/8" fillet weld all around
Length: 24" perimeter
Total capacity: 24 × 0.928 × 14 = 312 kips >> 12 kips ?

Real-Time Capacity¶

Live Calculations:

As user adjusts weld size:

Size: 1/4" ? Capacity: 78 kips (load 12 kips) ?
Size: 3/16" ? Capacity: 59 kips (load 12 kips) ?
Size: 1/8" ? Capacity: 39 kips (load 12 kips) ?
Size: 3/32" ? Capacity: 29 kips (load 12 kips) ?
Size: 1/16" ? Capacity: 20 kips (load 12 kips) ?? Marginal

AWS Compliance¶

Automatic Code Checks:

AWS D1.1 requirements:

? Minimum size: 1/8" for 1/2" plate (D1.1 Table 2.4)
? Maximum size: 3/8" for 1/2" plate (1/16" less than thickness)
? Minimum length: 4× weld size = 4 × 7/8" = 3.5" ?
? End returns: 2× weld size = 1-3/4" (added automatically)
? Effective throat: 0.707 × 7/8" = 0.618" ?

Status: AWS D1.1 COMPLIANT ?

If non-compliant:
? "Weld size 1/16" < minimum 1/8" for plate thickness"
   [Auto-fix to 1/8"] [Override with justification]

Cost Optimization¶

Minimize Weld Metal:

Connection options:

Option A: 7/8" all around (24")
Weld volume: 0.385 × 24 = 9.2 in³
Cost: $45 (weld metal + labor)

Option B: 5/8" all around (24")
Weld volume: 0.196 × 24 = 4.7 in³
Cost: $28 (save $17!)
Capacity: Still adequate ?

Option C: 1" intermittent (6" long, 12" o.c.)
Weld volume: 0.5 × 12 = 6.0 in³
Cost: $32
Capacity: Adequate ?

AI recommends: Option B (best value)
"Save $17/connection × 50 connections = $850"

3D Weld Preview¶

Interactive Visualization:

3D model shows:
- Weld plate (red steel)
- Embedded bars (green rebar)
- Weld beads (orange lines)
- Concrete (gray)

Rotate to inspect:
- Weld accessibility (can welder reach?)
- Clearances (adequate space?)
- Sequence (weld order)

Export for fabricator review

Weld Symbols¶

Automatic AWS Symbols:

AI generates standard AWS weld symbol:

        7/8"
    ???????????
    ?  Fillet  ?
    ?    AR    ? (all around)
    ?    FW    ? (field weld)
    ????????????

Placed on drawing automatically
Conforms to AWS A2.4 standard
Fabricator understands instantly

Best Practices (v7.0)¶

Use AI Features:

? Let AI size welds (optimal, code-compliant)
? Review cost optimization (significant savings)
? Check 3D preview (avoid fit-up issues)
? Trust AWS compliance (automatic verification)

Typical Weld Sizes:

Plate Thickness  Min Weld    Typical    Max Weld
1/4"             1/8"        3/16"      3/16"
3/8"             1/8"        1/4"       5/16"
1/2"             1/8"        5/16"      7/16"
3/4"             3/16"       3/8"       11/16"
1"               1/4"        1/2"       15/16"

Rule: Max weld = thickness - 1/16"
