Butt welds are the appropriate choice for pipes that are 2 inches or more in diameter. This type of welding involves joining two pieces of material end-to-end, aligning their faces to form a single continuous seam. Butt welding is ideal for larger diameter pipes because it creates a strong and integral join that can withstand high pressures and stresses typically seen in plumbing and industrial applications.

For larger pipes, the butt weld process also allows for better access and finishes since it does not require the added space that might be necessary for fillet welding, which is used for corner joints or lap joints. On the other hand, while TIG and MIG welding can be employed for various applications, they do not specifically address the criteria that butt welding meets for larger diameter pipes.
