In fact, welded or esoteric, without welding, or cracks and other defects, the strength will be greatly reduced, and the use of steel plate are generally in force or place very good welding pressure, it is easy to have an accident.
Not necessarily, very thin plate, no opening, but also guarantee penetration, but also through nondestructive testing
