The length and location of weld lines in a welded joint shou

The length and location of weld lines in a welded joint should be such that:

Select one:

1. They are parallel to the applied forces

2. They are perpendicular to the applied forces

3. The applied force should pass through the centroid of the weld lines

4. It doesn’t matter as long as the weld resists the external forces

Solution

Answer: the applied force should pass through the centroid of the weld lines,so that weld strength is uniform above and below the centroid of weld.
