Do mechanical engineers need to travel frequently?

In practical work, the concept of mechanical engineer is already a vague concept. The fields it covers are also diverse and different. Especially in the recruitment process, you will see that the recruitment of mechanical engineers involves practical work, such as technology, equipment management and maintenance, after-sales service, etc., and it is also uneven. But most of the details are mainly about equipment maintenance, and there is no need to travel frequently. If it is after-sales service, you need to travel frequently. If the factory where you work is an equipment processing factory, you need to travel frequently for machine tool debugging. In other cases, for example, technicians will travel for machine tool purchase and trial processing, and for product quality problems, but rarely.
