Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a lifting workbench for welding. Background Art

[0002] Welding, also known as welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. 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, welding may bring danger to the operator, so appropriate protective measures must be taken when welding. The harm that welding may cause to the human body includes burns, electric shock, visual impairment, inhalation of toxic gases, excessive ultraviolet radiation, etc. In the past, the welding workbench on the market was not convenient to adjust the height of the workbench, and there was a problem of inconvenience in using it in some situations where different heights were required. For example, it was very inconvenient for workers of different heights to use it, and the workpiece was directly rotated during welding. The temperature was too high and it might burn oneself, and fine welding slag would be produced. The operator would inhale these fine welding slag more or less, and invade the liver, lungs and blood through the respiratory tract, seriously endangering the health of the operator.
