Seam Welding Process Explanation:
Seam welding is a type of welding process that involves making a series of overlapping spot welds to form a continuous seam. Here is an explanation of why seam welding is considered a continuous spot welding process:
Continuous Spot Welding:
- Seam welding is a variation of spot welding where the electrodes move along the joint, producing a continuous weld rather than individual spot welds.
- The electrodes apply pressure and current to the workpieces, creating a series of overlapping welds along the seam.
Advantages of Seam Welding:
- Seam welding is a high-speed process that can create a leak-proof and hermetic seal along the entire length of the seam.
- It is commonly used in the automotive industry for welding fuel tanks, exhaust systems, and other components where a continuous, watertight seal is required.
Comparison with Other Welding Processes:
- Seam welding differs from arc welding processes like MIG or TIG welding, which use a continuous electrode to create a molten pool of metal that solidifies into a weld bead.
- It is also distinct from multi-spot welding processes, which involve making multiple individual spot welds at different locations along the joint.
In conclusion, seam welding is categorized as a continuous spot welding process because it involves creating a series of overlapping spot welds to form a continuous seam. This process is widely used in industries where leak-proof and continuous welds are required.
