The proper order for performing a bevel pipe weld typically begins with the root weld. The root weld is the initial pass that fuses the edges of the bevel together, ensuring that there is a solid foundation for the rest of the weld. This step is crucial because it guarantees that the joint is properly aligned and secure before additional welding operations are conducted.

After the root weld is complete, the next step is to perform the lap weld. The lap weld adds material along the joint, reinforcing the connection and helping to prevent issues such as undercut or lack of fusion in subsequent passes. This step is vital for achieving the necessary strength and integrity in the weld.

Finally, tack welds are utilized at various points as necessary throughout the welding process to hold the workpieces in alignment. Tack welding is typically performed intermittently during the procedure, ensuring that everything stays positioned properly while the root and lap welds are conducted.

This sequence is essential for achieving a strong and effective bevel pipe weld, as starting with the root weld allows for stability and alignment, which is further enhanced by the lap welds, while tack welds serve a supportive role throughout the process.
