What is the most common cause of excess Splatter? Travel Speed Arc length

## Step 1<br />The problem is asking for the most common cause of excess splatter in welding processes. Splatter refers to the molten metal that is expelled from the weld and does not form part of the final weld. This can occur due to several factors, including the travel speed and the arc length.<br /><br />## Step 2<br />The travel speed refers to the speed at which the welding torch or electrode is moved along the joint. If the travel speed is too fast, the molten metal may not have enough time to solidify, leading to excess splatter.<br /><br />## Step 3<br />The arc length refers to the distance between the electrode and the workpiece. If the arc length is too long, the molten metal may be expelled further away from the joint, leading to excess splatter.<br /><br />## Step 4<br />However, the most common cause of excess splatter is generally considered to be an incorrect arc length. This is because the arc length has a more direct impact on the molten metal's ability to solidify and form part of the final weld.
