Often heard the words "welder", "welder", in the welding industry, people do not have deep contact with the industry, they may mistakenly think that the welder and the welder is the same meaning.
But in fact, the welder and the welder are different concepts, the welder is only one of the types of welders, and can not represent the group of welders.
Welders, that is, the implementation of welding workers.
Is the use of appropriate welding methods, reasonable welding process, appropriate welding equipment, the use of the same material or different materials of filler, to the metal or non-metallic workpiece tightly connected to a work type.
Welders include electric welding, gas welding, pressure vessel welding, submerged arc welding, gas welding, flash welding and other types of work, electric welding is just one of them.
Welder, is a special metal welding jobs in the machinery manufacturing and machining industry, mastery of electric welding welding technology.
Often need to master, including basic knowledge of welding, welding materials, welding preparation, welding process operation basic skills, welding deformation correction and defect prevention measures, welding quality management and safety measures within a number of content.
In short, the welder and the welder is a contained and contained relationship.
It is just that the welder's market demand, high employment rate, better pay, more practitioners, more representative, so in the eyes of the people who do not know so, the welder naturally equated with the welder.
To be a welder, you have to take a welder's license, which is an induction certificate that all welders need to take.
But whether you are a welder, gas welder, submerged arc welder or any other type of welder, welder's license exam content is the same, the name of the certificate is called "special operations license (melting welding and thermal cutting)".
From the certificate can not see any difference, it does not matter that people will be confused with the concept of the two.
Welding is a very hurtful operation, whether it is a license, review or renewal of the license, the physical conditions are required.
Generally, candidates are required to hold a medical certificate of physical fitness above the second class B medical institution, so you can imagine how much damage the welder does to the body.
Especially the welder, operation for a long time, on the skin and eye damage.
Because of this, safety training for welders is necessary, not only for the lives of others responsible, but also in learning how to protect themselves.
