Do a few practice runs on scrap material to adjust your settings and technique. This helps you adapt to the specific conditions and materials you will be working with.
Begin by thoroughly cleaning the pipe to remove dirt, grease, rust, or paint using a wire brush or grinder. Proper cleaning ensures better arc stability and weld penetration. Next, cut the pipe to the required length using a pipe cutter or saw, making sure the cut is clean and square.
Bevel the edges of the pipe to about 45 degrees using a grinder or beveling machine. This creates a V-shaped groove, which helps achieve deeper penetration and a stronger weld. Leave a small land (approximately 1/32″) at the edge to help control the root pass.
Proper fit-up is crucial for quality welds. Use pipe wedges or spacers to maintain the correct root gap and prevent the pipe from closing during welding. Ensure the pipes are aligned accurately using pipe clamps or tack welds. Check the alignment with a level or straightedge to avoid gaps or misalignments.
Apply tack welds at regular intervals to secure the pipes in place. Feather the tacks, blending them into the joint to ensure a smooth transition for the root pass. This helps prevent the pipe from shifting during welding and maintains the correct alignment.
Use DC electrode positive (DCEP) polarity with 6010 rods for deep penetration and stable arc. Adjust the amperage based on the rod diameter and pipe thickness. Refer to manufacturer recommendations, but typical settings for 1/8″ rods range from 75–125 amps, depending on position and joint design.
Keep 6010 rods dry and in a rod oven if possible, as moisture can affect performance. Proper storage ensures optimal welding results and prevents defects caused by contaminated electrodes.
Choose the appropriate welding position (1G, 2G, 5G, or 6G) based on pipe orientation and whether it is fixed or rolled.
Maintain a tight arc length (about the rod diameter) and a slightly dragging (negative) rod angle for downhill welding, or a pushing (positive) angle for uphill welding. Proper arc control is vital for achieving strong welds.
Start the root pass at the tacked joint. Keep a short arc and consistent travel speed. If the arc drifts to one side, adjust the rod angle to center it. Aim for a consistent “keyhole” at the leading edge of the weld pool, indicating proper penetration. Adjust travel speed and rod angle to maintain this keyhole without burning through.
After the root pass, immediately run a hot pass to clean up the root and prepare for filler passes. Overlap the root by a good margin and use a slightly higher amperage if needed.
Use weaving or stringer beads as required. Ensure each pass is cleaned thoroughly before the next. Clean between passes to remove any slag or spatter, ensuring smooth and strong welds.
The final weld layer should be smooth and even, blending well with the pipe surface. A well-executed cap pass enhances the weld’s appearance and strength.
Check for consistent penetration, lack of porosity, and absence of cracks. A thorough visual inspection helps identify any defects that need correction.
Remove slag and spatter using a chipping hammer and wire brush. Proper cleaning ensures the weld’s integrity and prepares it for any required testing.
Perform any required non-destructive testing (NDT) such as dye penetrant or radiographic inspection, depending on application standards. Testing confirms the weld’s quality and compliance with industry standards.
Always wear protective gear, including a welding helmet, gloves, and fire-resistant clothing. Ensure your workspace is well-ventilated and free of flammable materials. Avoid moisture contamination of electrodes to prevent weld defects. Proper handling and storage of welding rods are crucial for achieving high-quality welds.
