Clean Surfaces- Ensure that the surfaces to be welded are free from rust, oil, grease, and other contaminants. This can be achieved through wire brushing, grinding, or chemical cleaning.
Correct Fit-Up: Proper alignment and spacing of the rebar are crucial.
Misaligned or improperly spaced bars can lead to weak welds and structural issues.
Travel Speed and Angle: Control the speed at which you move the welding torch and maintain the correct angle to ensure proper penetration and fusion.
Stringer Beads: Use stringer beads (straight-line welds) instead of weave beads (zigzag pattern) to reduce the risk of slag inclusions and improve weld quality.
