Then backweld from 2 to 1, and allow weld to cool before welding from 3 to 2and so along to 10. Complete the weld at B. WELDING ON PATCH OF FIGURE 47: Operation 4. Remove the rivets adjacent to the weld on the mud-ring and side sheets, also remove the staybolts that would be affectedby the heat. Start to weld at A. Th
