What values are needed for creating a Class A weld between two pieces of mild steel?
To determine the values for creating a Class A weld between two pieces of mild steel, you need to consider the electrode tip diameter and electrode force.
Electrode Tip Diameter:
The electrode tip diameter depends on the specific welding process being used. For example, in shielded metal arc welding (SMAW), the electrode tip diameter ranges from 1.6 mm to 6.4 mm, while in gas tungsten arc welding (GTAW), it can be as small as 0.8 mm. You would need to specify the welding process to determine the exact electrode tip diameter.
Electrode Force:
The electrode force, also known as the welding force, is the pressure applied to the electrode during welding. It helps in establishing good contact between the electrode and the workpiece. The appropriate electrode force depends on factors such as the welding process, electrode size, and material being welded. Generally, it ranges from 100 Newtons to 700 Newtons.
