# Weld Group - Angle Weld

# Notation and Units

## Metric and Imperial Units

The above weld group stress equations may be used with both imperial and metric units. As with all mathematical calculations care must be taken to keep consistent units throughout. Examples of units which could be adopted have been provided below:

# Notation

- A
_{W}= area of weld group, in^{2}or mm^{2} - a = weld throat thickness, in or mm
- B = width of weld group, in or mm
- H = height of weld group, in or mm
- x = distance to centre of area (centroid), in or mm
- y = distance to centre of area (centroid), in or mm
- I
_{WX}= second moment of area of weld group in x direction, in or mm - I
_{WY}= second moment of area of weld group in y direction, in or mm
