What do I need to do without loss? What certificates do you usually take? What is the prospect of development? What is the salary in the field of petrochemical industry?

Inspealless testing, as the name suggests, it is detected by the premise that it does not damage the object. The most typical is the weld detection. Its detection methods are diverse, such as magnetic powder detection, penetration detection, ultrasonic detection, ray detection, TOFD detection, etc. It does not belong to the field of petrochemical and chemical industry, and the construction field of electromechanical engineering is only used for petrochemical industry). The non -destructive test certificate is divided into three levels, and level 1 is a primary qualification. It means that there are relevant basic knowledge that can participate in the work site where the lossless testing can be participated. Level 2 is a intermediate qualification, which can include all jobs at level 1, and also include legal responsibility testing. Records and reports can also act as relevant non -destructive testing responsible persons, and can review the test report and sign it; level 3 is a senior qualification, covering level 1,2, and can guide the work of level 1,2 personnel to review non -destructive testing without damage testing. The plan, formulate the assessment of non -destructive testing process, as the person in charge of the loss of damage testing technology, etc., and the test conclusions given by the level 2 of the arbitration level 2 can be said to be all tasks that can dry out without loss of detection. Generally speaking, non -destructive detection major is a rising industry, because as long as there are strict requirements for welding, it will be tested. It does not belong to the construction unit. Generally, it is a third party or even a four -party identity.
