Why do oval heads and dish-shaped heads both have straight edge sections?

2009-03-11View Original

Thread Content

This is to prevent the connection ring weld between the head and the cylinder from coinciding with the edge stress action area. Not only may there be welding defects in the girth weld, but also there will inevitably be welding residual stress. If it overlaps with the edge stress, it will be very detrimental to the stress. For this reason, the heads are equipped with straight edge sections to improve its stress condition.
