If certain preventative steps aren't followed, even an arc welding robot can create spatter.
The molten metal droplets that make up spatter are messy, dangerous, and wasteful. Spatter is hazardous to operators. It creates rough and unsightly welds and it is very difficult and time-consuming to remove.
However, spatter doesn't have to be an issue. Clean up your spatter with these five tips.
Up the Voltage
Cut down on spatter by adjusting your voltage. Voltage is closely tied to the welding arc's length and the heat input of the weld. Find the right balance, so the weld is being created with the right intensity.
Make Sure the Welding Surface is Clean
One simple way to avoid spatter is to keep your welding surface free from contamination. Substances like oil may trigger the welding power supply to alter parameters settings - creating spatter before and after the right adjustments are made.
Anything that oxidizes the weld pool (such as rust) may cause bubbles - which burst, creating more spatter. It's best to clean the surface and avoid the mess. Remove buildup with an abrasive tool or chemical.
Secure the Welding Environment
In the fight against spatter, wind is an enemy. Make sure your shielding gas isn't being affected by air circulation. Another environmental problem that causes spatter, cable grounding, can be easily fixed. Make sure cabling is secure and on clean surfaces, otherwise, you may have weld altercations.
Find the Right Torch Angle
Angling your torch with the wire in front may make a nice, smooth weld, but it shoots spatter outward. A drag angle with the wire behind, keeps spatter in the weld pool.
Pay Attention to theShielding Gas and Wire
Make sure your shielding gas and wire are preventing spatter, not contributing to it. Argon gas can minimize spatter, but it can change other aspects of the weldment. Lots of wires have deoxidizing substances in them, which will decrease the amount of spatter. Flux cored wires are a good safeguard against spatter.
