Horizontal Welding Position Diagram [exclusive] -

This is the angle of the electrode in relation to the vertical plate. In a horizontal butt weld, this is typically 90 degrees (straight in) or tilted slightly upward (5 to 10 degrees) to push the puddle against gravity.

Horizontal is – easier than vertical/overhead but harder than flat because gravity pulls metal downward, not away from the joint. horizontal welding position diagram
