answer 6 7 8

Travel at a slower speed. At any one voltage setting, amperage is required to melt the wire the it is fed. more, faster less, faster more, slower the same, faster Slight changes in can be used to control the weld as the groove spacing changes.

Solution

6. At any one voltage setting, more amperage is required to melt the wire the faster it is fed.

This is because more melt is availabe that is to be melted, i.e. as volatge remains constant in this welding, thus to match faster electrode feed rate the amperage has to rise.

7.slight changes in welding gun angle can be used to control the weld as the groove spacing changes

Welding gun angle is the angle between the welding gun and the workpiece. Hence to control the weld as groove spacing changes the welding gun angle must be changed.

8. A weld that is high and has little or no fusionis too \"cold\". To correct this stop welding and make the needed adjustments.

The adjustment is to be made in electrode feeder or power supply, we have to stop welding in order to allow the weld to cool
