|
| 1. | The area to be welded does not
need to be considered as far as cleanliness and preparation.
|
|
| 2. | The fourth number in the coding
system of a welding rod ( 6013 )will tell you the chemical analysis of the flux,
polarity and the penetrating capacity of the rod.
|
|
| 3. | After you have welded a bead
you can tell that your travel speed was too fast by looking at the bead and observing that the bead
will be narrow and the ripples will be pointed.
