To professionals all around the industry, I am here to present you a problem. We have  shortage of personnel for our industry. The average age of a welder in the USA is 55; the wave of coming retirements will leave manufacturers at a disadvantage. The American Welding Society estimates that by 2020 there will be a shortage of 290,000 professionals, including inspectors, engineers, and teachers. “We’re dealing with a lost generation”, they say (link)

Hi again, dear readers. I am greeting you after a long hiatus in my writing, in relation with my work, the caring after my baby boy and my health. Anyway, I am back again and today I will be writing further about  ASME IX, for you to better understand WPSs and PQRs. Remember, my post are oriented for the people that will take the API 653 certification exam. (more…)

I am writing this post because of this video that a good friend  sent to me about vacuum box testing, that I want to show you. Besides, I will give you instructions for the construction of your own flat vacuum box, but first a little background.

Hi friends. Today´s article is really short, but is to let you know of the new version of the API 653 exam Simulator. This 2.0 Version has 100 questions total, an improvement of 52 from the previous version. The new simulator has some bug fixes from the former one, given that it did convert percentages to decimal points, an issue we discovered late.

This version still has to improve, and I promise that I will make my best to update it within a week to the subscribers of my blog. I have to improve the result screen and allow the user to go back to solve the test. Remember that I have a dayjob and little time, jeje.

What is the objective of this simulator? To get you accustomed to the test environment, mimicking the conditions of the actual exam. As far as I know, this simulator is one of its kind.

I took special consideration to the fact that some 70% of questions in the actual exam are from the API 653 standard, so the most of the questions in this simulator were taken from API 653. By the other side, there are new questions that aren´t in my questions series.

Hi friends. I am longing to make it in the integrity field. I mean, I want to make it in the tanks, in the pipes and in the pressure vessels and static equipment.

Here is a gift for you

Today I am writing you about the API 580 certification, the same I talked about in this article

On february 2, I received this mail from the guys of prometric that contained a pdf file. I opened up the PDF file and read that I  achieved a passing grade and i am now certified to conduct rbi inspections. I dont have the experience yet though. Here is a screenshot of the document.

API-580-Certified

But as for the exam, I actually just studied some 3 days total. I really didn’t have much time in the previous months to study, and just one month before the exam, the API 580 course I was due was cancelled. I thought I had no chance. In the last week, I read the RP on the bus while in my conmute, I read the RP while I was having my lunch, and I reviewed some questions and answers I had in an spaced repetition software (in a very disorderly way).
I almost flunked. I got 50 questions right, just to a little over the 71% needed. What helped me was that I can understand english well and generally have been good in multiple choice exams troughout my life.

During the exam, all you had to do is make sure that you get the 49 questions you need in order to pass. Be sure of 49, and you can do anything to the others, from guessing to discarding to whatever. And if you passed, congratulations on this significant professional acomplishment.

And continuing with my goal to completely prepare you for these exams, here are more questions for the API 653 Certification examination.

MICROBIOLOGICALLY INDUCED CORROSION QUESTIONS

I am bringing you today 25 questions about Microbiologically induced corrosion (MIC). You can download them Here. Microbial corrosion, also called bacterial corrosion, bio-corrosion, microbiologically influenced corrosion, or microbially induced corrosion (MIC), is corrosion caused or promoted by microorganisms, usually chemoautotrophs. It can apply to both metals and non-metallic materials (Wikipedia)

For the exam, I can´t tell you how many questions about this subject will show up. Maybe none. Anyway, I prepared these questions with the intention to make you really knowledgeable to the subject.
