Solution to improve weld quality – reduce spatter in stick welding

During stick welding, spatter is one of the most common defects that can affect both weld quality and surface appearance. Molten metal droplets are ejected and solidify around the weld area, not only creating a mess but also posing risks of burns or damage to surrounding materials. Therefore, evaluating and controlling the level of spatter is essential to improve work efficiency and ensure the reliability of the final product.

There are several causes of spatter during welding:

Improper welding current
Unstable arc length during welding: An arc that is too long or too short can lead to spatter
Incorrect electrode or torch angle: An improper angle can cause more molten metal to be ejected
Inconsistent welding speed: Irregular travel speed makes the arc unstable, resulting in spatter
Contaminated electrode or base material: Dirt, oil, or other impurities on the surface can cause spatter.

Effects of spatter defects:

Reduces weld quality
Affects visual appearance
Increases cleaning costs
Poses safety hazards

How to prevent spatter defects:

Adjust the welding current
Control welding technique and ensure materials are clean before welding
