Jan 4, 2024 · Burn-through occurs when the weld penetrates deep enough to reach the weld root. Basically, you accidentally melt the entire base metal thickness. This is why burn-through is also known as melt-through.

Jul 1, 2015 · Burn through results in a depression, almost a crater, on the pipe I.D. surface. This is a result of burning through a thin root pass area while depositing the first fill pass (hot pass), and the molten metal sucks back into the pipe wall in that area.

Dec 29, 2022 · The most common cause of welding burn through is excessive heat input into the weld joint, which is dependent on the amperage. If the amperage (current) is too high, the heat input is greater, and holes are burned in the weld.

Jan 1, 2024 · In pipe welding, burn through can be a common issue due to the confined space and the potential for inadequate shielding gas coverage. Back purging is a technique used to prevent burn through and ensure the integrity of the weld in pipe welding.

Jan 6, 2023 · Welding burn-through occurs when the heat generated during welding exceeds the heat-absorbing capacity of the base material or weld metal below the welding run. There are multiple reasons that cause burn-through in welding.

Mar 6, 2024 · Learn about the common causes of welding burn through, from improper settings to material thickness, and discover effective prevention techniques. Our expert guide provides valuable insights to help you avoid this welding defect and achieve flawless results.

Aug 2, 2024 · In this video I will be sharing a few tips I learned over the years of pipeline welding on how to fix a burn through. The term "burn through" is referring to when we burn through our bead...

Sep 10, 2021 · Smaller wire will help. Keep the power down and add some feed speed. Don’t dwell on the edges or you will burn through for sure.

Sep 30, 2024 · Burn-through is a significant welding defect that can compromise the strength and integrity of a welded joint. By understanding the causes of burn-through, welders can take steps to prevent it, ensuring that their welds are structurally sound and safe.

Jun 14, 2023 · Burn-through happens when your welder is set to a higher amperage which makes a hotter weld while at the same time welding a thin piece of metal causing it to blow through the metal creating a hole. To prevent this you need to turn down your amperage and make smaller welds to keep the base metal from getting too hot.
