Technical Field
The application relates to the technical field of welding dust removing equipment, and particularly discloses dust removing equipment for welding automobile parts.
Background
Welding, also known as fusion welding, is a process and technique for joining metals or other thermoplastic materials, such as plastics, by means of heat, high temperature or high pressure. The energy sources of modern welding are numerous and include gas flames, electric arcs, lasers, electron beams, friction and ultrasound. In addition to use in factories, welding can also be performed in a variety of environments, such as in the field, underwater, and in space. Wherever welding may present a hazard to the operator, appropriate safeguards must be taken when welding. The possible injuries to the human body caused by welding include burn, electric shock, vision damage, inhalation of toxic gas, excessive ultraviolet irradiation and the like.
Some automobile parts are usually placed on a welding table with gaps for connection, and in the welding process, a lot of welding smoke which pollutes the environment and affects the health of welding workers is generated, if the welding smoke is not recovered in the welding process, the environment is possibly polluted or the health of the workers is possibly affected, at present, when the welding smoke is recovered, a welding smoke filtering shell is often used, most of the welding smoke can be recovered, but in the welding process, a small part of the welding smoke can not be recovered, so that the environment is polluted, and the like, therefore, the inventor provides dust removing equipment for welding the automobile parts in view of the problem, and aims to solve the problem.
