Mcdonald's Near Alanya, Antalya, Type 1: Full penetration welds (Typically Double welded), Type 3: Single welded partial penetration welds, Type 4, 5 and 6: Various Lap welds (rarely used), (For the radiography = Full, Spot, Nil respectively), 9. The length of elongated inclusion depends on the test piece thickness, for instance, any elongated slag inclusion will be unacceptable if the length is more than 1/8 inch when the thickness of the specimen is between 0 to 3/8 inch. 1/8-inch (3 mm) maximum or 20% of material thickness (t), whichever is smaller. Division 1 covers pressure up to 3000 psi, Division 2 has an alternative rule and covers up to 10,000 psi and Division 3 can be used for pressure higher than 10,000 psi.
