When the weld seam "boils" while TIG- oder MIG-MAG welding, it appears porous, restless, and shows increased bubble formation. This effect usually occurs when the shielding gas supply is incorrect or the wrong shielding gas is used.
Possible causes and solutions
Shielding gas supply is missing
Remedy: Check. See also article: Too little or no shielding gasWrong shielding gas
Remedy: Select according to the operating instructions. See also article: Which shielding gas for which welding process
Explanation of term – "seam is boiling":
The expression "seam is boiling" describes a restless, bubbling weld seam caused by insufficient protection from oxygen and nitrogen. This makes the melt unstable, leading to pores, spatter, and an uneven surface.
Note:
The problem of boiling welds can also occur with electrode welding. This is usually caused by insufficient shielding gas supply due to electrodes that are unsuitable for the workpiece or are damp.
