Multipass welding is an essential technique for joining thick materials and achieving strong, long-lasting welds. By depositing several layers of weld metal to fully fill a joint, it provides superior strength, better control of heat input, and reduced distortion compared to single-pass methods
Multi-pass welding is required when metals are so thick that a single pass cannot create a strong weld. This process is widely used in structural steel, pipeline construction, and heavy equipment manufacturing. Successful multipass welding requires careful planning before striking the first arc, ensuring both the quality and efficiency of the final weld.

Key benefits

  • Better control of heat input

  • Reduced risk of weld defects

  • Creates stronger joints in thick materials

  • Essential for materials thicker than 3/8 inch
