Summarize the disadvantages of having to bevel a plate prior to welding.
What will be an ideal response?
There are several disadvantages of having to bevel a plate before welding:
*Beveling the edge of a plate adds an operation to the fabrication process.
*Both more filler metal and welding time are required to fill a beveled joint than are required to make a square jointed weld.
*Beveled joints have more heat from the thermal beveling and additional welding required to fill the groove. The lower heat input to the square joint means less distortion.

A laser level projects a laser beam, a single beam of light projected by a mirror continuously in a full circle. The leveling rod with detector is positioned in two different locations. The reading to the left of the instrument, where the laser beam and detector are aligned level, is 46 5/8". The reading to the right of the instrument is detected on the leveling rod at 46 3/4". What is the difference in elevation at the two locations?
