If the anchor bolts used for installing mechanical equipment are not long enough, can they be extended by welding?

Dear sea friends: Our company is installing a fan. Since the embedded foundation bolts were not long enough, the construction team cut them off and then welded extensions to them. Is this approach in compliance with the standards? Are there any standard regulations?
It can be installed, but what’s welded on won’t be as secure as the whole unit, right?
This is way too casual! It can’t be done this way; even if it’s taken apart and rebuilt, welding isn’t an option! It’s moving equipment, not stationary equipment
This approach is too casual; the welding is not as strong as a solid structure.
Bolts are not allowed to be welded or mechanically processed again.
It can be connected, but not in this way; first, it needs to be enclosed with three round steel bars around it, followed by extended welding.
No! If there is enough time, use the equipment used to create holes in the walls for installing air conditioners and plumbing, and carry out grouting again
It mainly depends on how much vibration the device experiences; if there is a lot of vibration, it won’t work. Also, after extending it, the welded section should be buried underground, otherwise it will break again
It can be connected. Either fillet welding with reinforcement strips or stronger welds such as butt welding can be used, all in order to meet the requirements regarding the anchorage length; mechanical anchoring measures can also be applied at the ends, allowing the anchorage length to be reduced by a factor of 0.7. Tensile pull-out tests can be conducted under certain conditions.
