Improper support during the joining of tubes may lead to what issue?

Improper support during the joining of tubes can lead to misalignment. This typically occurs when the tubes are not held securely in place, which can cause them to shift or be positioned incorrectly relative to each other. Misalignment can result in uneven distribution of heat and filler material, ultimately compromising the integrity and effectiveness of the joint. Ensuring proper alignment is crucial for achieving strong, reliable connections between the tubes, as misalignment may lead to gaps or improper flow paths that can affect performance in applications like plumbing or HVAC systems.
