What is the consequence of not maintaining a proper gap when tacking pipe sections?

It can lead to ineffective welds
It has no impact on the final weld
It makes the pipe fit more securely
It only affects the appearance

The correct answer is: It can lead to ineffective welds

Maintaining a proper gap when tacking pipe sections is crucial for ensuring effective welds. If the gap is too large or too small, it can create issues that compromise the integrity of the weld. An improper gap may prevent the molten filler metal from adequately fusing with the base metal, which can result in incomplete fusion, decreased strength, and potential failure of the joint under pressure or stress. Additionally, a poor gap can cause uneven heating and cooling during the welding process, leading to warping or distortion of the pipe sections. This can lead to further complications in the fit and alignment of the installed piping system. Therefore, proper spacing is essential for achieving strong, durable welds that can withstand operational demands.
