Across 6. A protruding rim, edge, rib, or collar, as on a wheel or a pipe shaft, used to strengthen an object, hold it in place, or attach it to another object. 8. progression of welding is from left to right but the welds are deposited in short increments from right to left 11. using hammer blows to work metal and reduce residual stress 12. amound of buildup on the weld face or root of a weld with CJP 13. vertically straight, at a 90* angle to a horizontal surface 14. preplaced filler metal that will become completely fused into the root of a joint 15. maintains the root gap when yokes and strongbacks are used 18. cjp 19. weld used to hold parts in alignment until the final weld is made 20. the expansion and coatraction of material as it responds to temperature changes 22. pjp 23. written set of instructions for producing sound welds

Down 1. room temperature completely surrounding and object 2. stress remaining in a weldment as a result of heat 3. change in length for a material for a 1*C change in temperature 4. the discrepancy in internal alighment of two sections of pipe 5. the quanity of heat required to raise a unit mass of a substance one degree 7. movement of materials after the clamps are removed 9. supplementary information used to describe revisions or corrections to documents 10. a unit formed by welding together an assembly of pieces 16. piece of material notched at the weld joint used to hold material in alignment 17. an exactly horizontal surface 21. a u-shaped piece of material used to force plates into alignment
