What does it mean when a weld length is expressed in degrees?

When a weld length is expressed in degrees, it signifies the starting and finishing location for the weld. This method of indicating weld length is particularly useful when dealing with curved or radial structures, such as pipes or cylindrical surfaces. By using degrees, the print can precisely communicate the extent of the weld around a circumference, specifying how far around the round object the weld should be applied. This is essential for ensuring the structural integrity of the joint, as it provides clear directions on where the weld begins and ends, making it easier for welders to visualize and execute the required welds on complex shapes.
