Final answer:
The statement pertains to engineering practices related to welding and fabrication, indicating that full-length welding or material removal isn't necessary unless specified by an engineer. Compliance with the engineer's instructions is crucial for the structural integrity and safety of the project.
Step-by-step explanation:
The statement “Need not to be welded full length or removed unless specified by the engineer” refers to a specific instruction or standard practice in the field of engineering, particularly concerning the construction and fabrication of structures or equipment. When dealing with welding operations, it is not always necessary to weld an entire joint or length of material. The extent and type of welding required are usually determined based on the structural needs, the materials involved, economic considerations, and the design specifications provided by an engineer or a set of engineering design documents. However, if the engineer does not specify that a full-length weld is needed or that the material should not be removed, then the standard practice can be to only weld what is required to meet the structural and safety criteria, or to not remove any material unless this is stated.
It is critical that instructions and specifications provided by an engineer are followed accurately to ensure the integrity and safety of the structural element or system in question. Failure to comply with the specifications could compromise the structure's safety, potentially leading to catastrophic failure.
