There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound. In addition to being used in factories, welding can also be performed in a variety of environments, such as outdoors, underwater and in space. No matter where it is, welding may bring danger to the operator, so appropriate protective measures must be taken when welding.
