. 6. V-groove welds with backing are popular welds normally made with __ a) fast-freeze electrodes b) fill-freeze electrodes c) low-hydrogen electrodes d) fast-fill electrodes 7. Which of the following is not true about welding with low hydrogen electrodes? a) You should always whip the electrode. b) You should never use electrodes with missing flux. c) You should take only as many electrodes simpl the storage oven as you need. d) You should maintain a short arc.

## Step1<br />For question 6, we need to identify the type of electrode that is typically used for V-groove welds with backing. The options provided are fast-freeze electrodes, fill-freeze electrodes, low-hydrogen electrodes, and fast-fill electrodes. <br /><br />## Step2<br />V-groove welds with backing are typically made with fill-freeze electrodes. These electrodes are designed to provide a stable arc and good penetration, which is ideal for V-groove welds.<br /><br />## Step3<br />For question 7, we need to identify the statement that is not true about welding with low hydrogen electrodes. The options provided are: always whip the electrode, never use electrodes with missing flux, take only as many electrodes from the storage oven as you need, and maintain a short arc.<br /><br />## Step4<br />The statement "You should always whip the electrode" is not true about welding with low hydrogen electrodes. Whipping the electrode can introduce impurities into the weld, which can lead to defects.
