I often hear the words "welder" and "welder". For people who don't have much contact with the welder industry, they may mistakenly think that welder and welder are the same meaning.
But in fact, welder and welder are different concepts. Welders are just a type of welders, and cannot represent the welder group.
A welder is a worker who carries out welding work.
It is a kind of work that uses appropriate welding methods, reasonable welding technology, suitable welding equipment and fillers of the same material or different materials to closely connect metal or nonmetal workpieces.
Welders include electric welding, gas welding, pressure vessel welding, submerged arc welding, gas shielded welding, flash welding, etc. Welders are just one of them.
Electric welder is a special type of metal welding work in machinery manufacturing and machining industries, and has mastered welding technology.
It is often necessary to master the basic knowledge of welding, welding materials, welding preparation, basic skills of welding process operation, welding deformation correction and defect prevention measures, welding quality management and safety measures.
In short, welders and welders are an inclusive and inclusive relationship.
It's just that welders are very representative because of their large market demand, high employment rate, good salary and many employees. So in the eyes of people in unknown so, welders are naturally equivalent to welders.
If you want to be a welder, you must first take the welder's operation certificate, which is a post certificate that all welder practitioners need to take.
But whether you are an electric welder, gas welder, submerged arc welder or any other welder, the content of the welder's operation certificate examination is the same, and the name of the certificate obtained is called special operation certificate (welding and hot cutting).
You can't tell the difference from the certificate. Never mind, people will confuse these two concepts.
Welder is a very harmful operation, whether it is research, review or replacement, there are requirements for physical conditions.
Generally, candidates are required to hold a health certificate from a medical institution above Grade B. It is conceivable how much harm welders do to the body.
Especially welders, working long hours do great harm to skin and eyes.
For this reason, safety training is necessary for welders, not only to be responsible for other people's lives, but also to learn how to protect themselves.
