The man behind the welding mask is a student from Rajamangala University of Technology Lanna, Chiang Rai Campus, and he’s welding the steel in order to make exercise equipment to give to different communities in Chiang Rai. He and his fellow students spent their time after class to attend this activity. Such a great way to make the best use of their spare time! Apart from creating a piece work for people, they also gained advantages from making the equipment, for example, testing and improving their skills.
