Preparing for Seam Welding
Before seam welding, it is essential to prepare the workpiece properly. Clean the metal surfaces to remove any dirt, rust, or paint. Proper cleaning ensures better weld quality and reduces the likelihood of welding defects.
Setting Up the Arc Welder
Set up the arc welder by selecting the appropriate electrode and adjusting the current settings. For seam welding, a continuous electrode is typically used. Ensure that the electrode is properly inserted and tightened in the electrode holder.
Performing the Seam Weld
To seam weld, slowly move the arc welder along the joint or seam, applying even pressure to create a continuous weld. Take care to maintain a consistent speed and angle to ensure uniform weld bead formation. Repeat the process until the entire seam is welded.
Inspecting the Seam Weld
After completing the seam weld, inspect it for any defects or imperfections. Check for proper fusion of the metal sheets and ensure that the weld bead is continuous and evenly formed. If any defects are found, they should be repaired before the weld is considered satisfactory.
In conclusion, seam welding with an arc welder is a reliable method for creating strong and durable welds. By understanding the process and following proper techniques, you can achieve high-quality seam welds suitable for various applications.
