Question 1Refrigeration & AC - Assistant Engineer

The correct answer is A) Swaging tools can be used to expand an end of one tube to fit onto a tube of the same original outside diameter. Swaging is a process used in refrigeration repair to connect copper tubes without the need for flares or fittings. The swaging tool is used to expand the end of one tube so that it can be inserted into the end of another tube, creating a tight seal. This is a common technique for repairing refrigeration systems and making connections in the tubing. The other answer choices are incorrect because: B) Swaging tools are not used to remove soldered edges, C) they are not used for breaking in compressors, and D) swaging tools are still commonly used in refrigeration repair despite changes in the tool industry.
