We have a weldment that incorporates 0375-in-diameter steel rods and a 0060-in-thick sheet metal stamping of 1018 CR material. Hold the electrode slightly uphill and keep a short arc to gain better penetration and fusion.

Shielded Metal Arc Welding 6 Pipe 6G Uphill. Gas Metal Arc Welding Vertical Uphill and Downhill - YouTube. Vertical Up and Vertical Down.

If your metal is thicker than ¼ inch you will need to learn to weld uphill to avoid a lack of fusion. In short welds or if you are preparing to run your 3F or 3G test do a dry run. Each weld is the same 075 in.

When you weld in the vertical position you will either go up or down. The weld didnt look all that great because I was maneuvering around a camera and tripod. Strike the arc on a tack weld at the top of the pipe holding the rod perpendicular to the pipe.

Starting the arc welder stick is actually easy. Vertical-up or -down in robotic welding. One needs to strike it the same way as a match and lift it slightly and the rod will start burning on its own.

You should also learn how to weld uphill. The electricity of the welder will pass through the rod and the arc and will create a temperature of up to 7000 F at the point of contact. 7018 Uphill arc force - YouTube.

What patterns is used in uphill gas metal arc welding GMAW and what amperage should I use on 025-in. If its too ho. Plate using 75 percent argon25 percent carbon dioxide shielding gas.

If the power source has an arc force feature use it to your advantage. Arc Welding 101. Uphill stick welding requires the amps to be set not too hot and not too cold.

Pause briefly at the sides to allow the bead below to cool and the lower shelf to form. This video explains up hill arc stick welding with 7018 rods. When it penetrates through the pipe the operator will clearly hear the arc and a small keyhole will open behind the electrode.

The down side of that is that it takes away the control the welder has of cooling or heating up the puddle with arc length. The assembly is fixture and welded robotically using GMAW with CO2. Fillet perhaps including weaving.

Upon completion of this course the student should have developed skills for the pressure vessel and nuclear piping fields. A 140 amp stick inverter will burn a 18 3mm rod easily and is no bigger than a lunch box. Long with a 025-in.
