5 Essentials of Shielded Metal Arc Welding.pptx

SMAW NC II

1. 5 Essentials of Welding

2. 5 Essentials of Welding 1. Current current in welding is measured in amps, ampere or amperage.

3. 5 Essentials of Welding 2 . Arc Length is the distance from the tip of the electrode to the metal base.

4. 5 Essentials of Welding 3 . Travel Speed is the rate at which the electrode moves along the work.

5. 5 Essentials of Welding 4. Size of Electrode the common size of electrode used in welding are 3/32 inch to 3/16 inch.

6. 2 common type of Electrode use in Carbon Steel Pipes 1 . 6011 Electrode 6011 electrode are used in groove welds because it has smaller diameter enough to access the root of the joint. 2. 6013 Electrode 6013 electrode has a soft arc, with easily removable slag.

7. 5 Essentials of Welding 5. Electrode Angle electrode angle is used to control the shape of the bead and the amount of penetration.
