1 Tack Welds

Prevent edges of joint from drawing together ahead of electrode by tack welding the materials in position be- fore final weld.

2 Square Groove Weld

Good for materials up to 3/16 in (5 mm) thick.

3 Single V-Groove Weld

Good for materials 3/16 − 3/4 in (5-19 mm) thick. Cut bevel with oxy- acetylene or plasma cutting equip- ment. Remove scale from material after cutting. A grinder can also be used to prepare bevels.

Create 30 degree angle of bevel on materials in V-groove welding.

4 Double V-Groove Weld

Good for materials thicker than 3/16 in (5 mm).

Keep arc short and move at definite rate of speed. Hold electrode as shown to provide fusion into the corner. Square edge of the weld surface.

For maximum strength weld both sides of upright section.

3 Multi-Layer Deposits

Weld a second layer when a heavi- er fillet is needed. Use any of the weaving patterns shown in Section 13-9. Remove slag before making another weld pass.
