-4- WELDING PROCEDURES Out-Of-Position Welding (V ertical and Overhead) When welding out-of-position, the molten metal tends to spill out of the joint.
-5- V ertical Up T echniques for Fillet and Gr oove W elds 1. Make first pass root beads with a whipping technique. Whip the electrode tip out of the molten crater and up for a short time to let the crater cool before r etur ning the electrode tip to the crater area to add mor e weld metal.

-8- High-Deposition Welding High deposition applications includes groove, fillet, lap and corner welds in 3/16” and thicker plate welded with the work level or slightly downhill. These joints are capable of holding a large molten pool of weld metal as it freezes.
-9- T ravel fast, but not too fast for good slag coverage. Stay about 1/4” to 3/8” ahead of the molten slag. If travel speed is too slow , a small ball of molten slag may form and roll ahead of the ar c causing erratic bead shape, spatter , and poor penetration.
-10- Fillet and Lap Welds – The ideal fillet or lap weld has equal legs and a flat or slightly convex bead. Excess convexity wastes weld metal. A concave bead is susceptible to shrinkage cracks. Flat fillet and lap welds are made with the same general techniques as groove welds.
Lap W elds Use fillet weld procedur es for laps on 3/8” and thicker plate.

-24- Low Hydrogen W elding Low hydrogen electr odes are recommended for thr ee broad areas of application: 1. On low alloy , high carbon, high sulfur , or other steels wher e cracking is a problem. 2. When specified by governing codes. 3. For lowest costs on vertical, overhead and horizontal groove welds on heavy (over 1/2”) plate.
-25- Drag the electrode lightly . Since low hydrogen electr odes rely on the molten slag for shielding, never hold a long arc, whip, leave the crater , or move rapidly in any direction. Failure to follow these techniques may result in por osity and/or reduce mechani- cal properties.
-26- 2. For multipass welds, deposit a first pass bead using a slight weave. We emphasize the importance of moving into the corner to assure penetration into the corner . W eld additional layers with a side-to-side weave hesitating at the sides long enough to melt out any small slag pockets and minimize undercut.

-40- ARC RA YS can burn. 2.a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. Headshield and filter lens should conform to ANSI Z87. I standards.
-41- FUMES AND GASES can be dangerous. 3.a. Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases.When welding, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone.
FOR ELECTRICALL Y power ed equipment. 6.a. T urn off input power using the disconnect switch at the fuse box before working on the equipment. 6.b. Install equipment in accordance with the U.S. National Electrical Code, all local codes and the manufacturer’s recommendations.
-43- 7.b. Operate engines in open, well-ventilated areas or vent the engine exhaust fumes outdoors. 7.c.Do not add the fuel near an open flame welding arc or when the engine is running. Stop the engine and allow it to cool before refueling to prevent spilled fuel from vaporizing on contact with hot engine parts and igniting.
