Introduction of welding machine:

Welder is a type of work that uses proper welding method, reasonable welding technology, suitable welding equipment, filler made of the same material or different materials as the base metal, or even does not use filler, and closely connects metal or nonmetal workpieces by heating or pressurizing or both.

On July 2, 20201day, it ranked eighth among the jobs in short supply in the second quarter of 2020 100 released by Ministry of Human Resources and Social Security.

Welder hazard:

The welder's work often makes the work clothes completely wet. Chronic manganese poisoning is mainly seen in workers who inhale manganese dust for a long time. The clinical manifestations are mainly extrapyramidal nervous system symptoms, neurobehavioral dysfunction and mental disorders.

People who are exposed to manganese include manganese mining and smelting, manganese covered electrode manufacturing, welding and cutting manganese alloys, and industrial workers who manufacture and use manganese dioxide, permanganate and other manganese compounds. Welders are often exposed to radiation hazards during welding, such as strong light, infrared rays and ultraviolet rays. X-rays produced by electron beam in welding will affect the health of welders.

Welder grade:

According to their own welding skills, welders have obtained the technical titles of junior, intermediate, senior, technician and senior technician through the welding skill examination, and obtained the technical grade certificate issued by the state. Different titles can carry out different welding operations. For the welding of pressure vessels such as boilers, it is necessary to obtain a welding license for pressure vessels.
