To make threading electrode wire easier________. Straighten about 12 in. (305 mm) of the end of the wire and cut off any kinks cut off about 12 in (305 mm) of the end of the wire cut off about 2 in (50 mm) of the end of the wire strengthen about 2 in (50 mm) of the end of the wire and cut off any kinks Winch of the following is true of mill scale? The porosity it causes is most often confined to the interior of the weld. It is removed even for noncode welding. With GMA welding wire, deoxidizer eliminates the adverse effects of mill scale. It increases the chance of rusting. What can a welder do make the necessary adjustments in the step and manipulation to achieve a good weld? Keep the welding station clean and free from that can get in the way of your seeing the weld. Use a mixture of argon with 2% oxygen as the shielding gas. Make a few test welds. The _______ the density of n gas, the ______ will be the flow rate required for equal are projections. lower, lower lower, bigger higher, highr lowe, slower
13. To make threading electrode wire easier, straighten about 12 in, (305mm) of the end of thr wire and cut off any kinks
14. For mill scale The porosity it causes is most often confined to the interior of the weld.
It is confined to the interior of the weld because not visible on the surfaces, the porosity is not noticed.
15. A welder to make the necessary adjustments in the setup and manipulation to achieve a good weld, Make a few test welds.
Making few test welds will help the welder to understand the setup and manipulation is correct or not to achieve good weld.
16. The lower the density of a gas, the higher will be the flow rate required for equal arc protection.
Density is the main property to determin the effectiveness of gas for arc shielding .Flow rate is not proportional to densities.
