What's the difference between a high-pressure welder and an ordinary welder?

The difference between high-pressure welding machine and ordinary welding machine lies in the different welding methods: the welding method of high-pressure welding machine is pressure welding; The welding method of ordinary welders is to closely connect metal or nonmetal workpieces with fillers of the same material or different materials. High-pressure welder refers to the welder who meets the welding requirements of pressure weld. Ordinary welders, in fact, are mainly aimed at the "fusion welding hot cutting operation" issued by emergency management (former safety supervision bureau).

Welding certificate is a summary of welding certificates of different grades.

Welders are divided into five grades: junior welder, intermediate welder, senior welder, technician welder and senior technician welder.

Therefore, the welder's intermediate certificate is only one level of the welder's certificate. The difference of meaning space is also the biggest difference between the two.

Fusion welding and hot cutting operations (electric welding, gas welding, arc welding, electric welding and gas cutting, etc. ) also called work permit. The issuing agency-Work Safety Supervision Administration has the necessary employment certificate. You don't work without a certificate. It is divided into fusion welding and hot cutting operations, pressure welding operations and brazing operations. The certificate is a magnetic card, which is common throughout the country.

The meaning of ordinary welder:

Ordinary welders, in fact, mainly focus on "welding and hot cutting operations" issued by emergency management (former safety supervision bureau), commonly known as "welder certificate", "welder certificate", "work permit" and "operation certificate". Fusion welding and hot cutting operations include gas welding, covered electrode arc welding and carbon arc gouging, submerged arc welding, gas shielded welding, plasma arc welding, electroslag welding, electron beam welding and laser welding. If you just want to go to work casually, it will be good to get the welder's certificate issued by the original "Safety Supervision Bureau" of the emergency management department. The certificate is tried for the first time every 3 years and updated every 6 years. It is used all over the country, and also in official website.

High-pressure welder refers to the welder who meets the welding requirements of pressure weld. Usually, it is a pressure vessel welder, a pressure pipe welder (argon arc welder) (downward welder), etc. Generally speaking, it is a welder who can weld the weld to the national standard nondestructive testing. High-pressure welding machine has always been one of the projects with the highest technical requirements and the highest salary in the welder industry because of its high welding operation requirements, difficult operation and strict construction and welding supervision.
