What is Arc Length in Welding?
The arc length is the distance from the electrode to the attachment point on the workpiece.
Why is arc length important in welding?
The arc length is important in welding because it determines the amount of heat that is transferred to the workpiece. Too much heat can damage the workpiece, while too little heat will not allow the weld to penetrate properly. Therefore, it is important to maintain a consistent arc length to ensure proper welds.
What is the correct arc length?
The correct arc length depends on the type of welding being performed. For example, TIG welding requires a shorter arc length than MIG welding.
How do you control arc length?
Arc length can be controlled by adjusting the position of the welding torch. For example, if the arc length is too long, you can move the torch closer to the workpiece.
Types of arc length in welding
There are 2 types of arc length in welding, which are:
- Short arc welding is a type of welding where the electrode is only in contact with the workpiece for a short period of time. This results in less heat being transferred to the workpiece, which helps to prevent damage.
- Long arc welding is a type of welding where the electrode is in contact with the workpiece for a longer period of time. This results in more heat being transferred to the workpiece, which can help to improve the strength of the weld.
