Today’s topic is about those who just do not contribute as they should.

Selling NDT

In the past few months I had the opportunity to represent NDT at international trade-shows. The nice thing about these shows is to see how other people market their brand or product.

NDT Integrity

Why integrity is key for all NDT tecnicians.

Knowing Your Favourite NDT Method

Knowing the ins and outs of your favourite NDT method is important for your career. Something else you need to know about is the inner workings of your employer.

This week’s topic is confidentiality.

NDT Market Research Shows

Non-Destructive Testing Equipment & Services Market worth $6.88 Billion by 2020. Ultrasonic testing and radiography are identified as one of the emerging Non-Destructive Testing

Road Safety vs Radiation Safety

Radiation safety can be compared to road transport safety. Although both are very important and are in dire need of being taken care of, the way in which they are dealt with can be quite concerning.

Dye Penetrant Testing and Pre-Cleaning

One of the myths in NDT is that Dye Penetrant Testing is becoming obsolete. However, in our high-tech society where many power stations, mines, pulp manufacturing plants etc. are aging rapidly and require fatigue crack detection, can the old NDT method, Dye Penetrant Testing be forgotten?

The illogical way of getting the job done

The complex working of our minds, both in ourselves and in others, can lead us to assume the logical path, which subsequently turns out not to be as logical as we might hope. Take the interview process. We are taught to present ourselves well, to be personable and build a rapport with the interviewer.

Life Lessons: Forgettng the basics

I'm sure we have all been there before, fresh of our first course and eager to prove to our superiors that our time spent working as assistants has been a waste of our talents. Quietly whispering to yourself, "it's about damn time" that first time the boss calls you into his office to inform you will be going on your first solo run.

Story Time Memories 2: - Dr H.O. Reisener

He also told us about his life and the fact that he trained in Germany before the 1939-1945 war. He had a Leica Camera with which he photographed many historical buildings in Germany. After the war he offered these photographs to the German authorities and it was used in the restoration of the buildings. He lent us the camera on several occasions and I remember using the telephoto lens that he had.

Story Time Memories 1: - Dr H.O. Reisener

The trip in those days - around the 1970 -1980 era - went fom Vereeniging via the Golden Highway past Uncle Charlies into Johannesburg central and out to the North through Hillbrow along Louis Botha Avenue onto the Old Pretoria Road. Hence to Halfway House, Zwartkops, Voortrekkerhoogte to Central Pretoria and out towards the Reisener residence near Sunnyside.

Down To Earth

Since the job had started in the late afternoon, the duration thereof ran into the night. When it got too dark to see without artificial lighting, one of the customers' labourers lent me an old halogen type floodlight that had been rigged to work straight from a 220V electricity supply i.e. fitting, cabtyre cable and plug.

Fumes for Fools 2

It was a routine Friday afternoon; braai fire ready for the first steaks, the 'senior' technician (let's call him Idiom - short for being an idiot and moron) had already finished three double brandy and cokes as was quite busy with his fourth.

Fumes For Fools

To my amazement I turned to my right hand side and noticed the cigarette burnt out still in my colleague’s mouth and his facial hair: eye brows, moustache and beard were totally gone.

Who you Calling Complacent

A bit of respect, prudence, and general manners goes a long way towards ensuring that you are requested by name to do repeat work for your customer.

Myth: One Becquerel

Fact: One Becquerel (Bq) does not represent a measurable health risk. It equals one radioactive decay (or disintegration) per second of any radionuclide and is part of a natural process. The truth is that most things we eat and drink contain naturally-occurring radioactive elements

NDT Level 3 Role

Following a survey conducted amongst current Level 3 Inspection personnel that posed the question 'What is the role of an NDT Level 3 Inspector in industry?' SAIW's Harold Jansen presents his findings.The need for competent inspection personnel is established via the statutory code while the rules for qualification, certification and relevant duties/responsibilities of personnel, are found in related standards.

What is a European Standard

Standards are all around us, even if we are not always aware of them. One example of a widely-used standard is the A4 size for sheets of paper. A standard is a document that sets out requirements for a specific item, material, component, system or service, or describes in detail a particular method or procedure.

Basic Introduction to Ultrasonics

Ultrasonic testing (UT) has been used as an NDT method for a number of years in general industry and there is still a fair amount of confusion regarding the capabilities and the terminologies of this method of testing. The intention of this article is to provide a better understanding of the "dark art" of ultrasonic testing to the "non-NDT" fraternity.

Presidents Report

I thank you for this opportunity, and ensure you of our commitment as council in the coming year to further improve the functioning of the institute to the benefit of you, a member of the Southern African Institute for Nondestructive Testing.

PBNDT Road Show

With the 18th WCNDT (World Conference on Non Destructive Testing) held in Durban behind us and all the vibe that went with it, SAINT (South African Institute for Non Destructive Testing) had to reassess its role with regards to the members and NDT in general for the South African industry. The SAINT Council did not want to lose the momentum generated during the hype that was created during the World Conference.

Reports: A Closer Look

NDT personnel are often required to compile reports for two primary purposes. The reports are used to communicate information to customers, colleagues and managers, and they are used to document the equipment and procedures used in testing and the results obtained. These results may be used so that the inspection can be repeated if necessary or built upon.

Intelligent Pigging

How do you demonstrate the integrity of a buried 18" schedule 40 pipe line that is used to transport crude oil from the middle of a tropical rainforest to the sea, 123km away, where ships can collect and transport the oil worldwide?

Course in NDT

In South Africa the NDT engineering curriculum at Universities is severely neglected. NDT is included in the undergraduate course content of only one university. This knowledge gap leaves the engineering fraternity vulnerable as they are unaware of what their contribution toward successful performance of NDT has to be.

ISO 9712 2005 Vs 2012

Changes from the third edition (ISO 9712 : 2005) includes: clarification of responsibilities for the certification body, the qualification body and the examination centre

SAINT Indaba Report

On the 15th of February 2013, SAINT held an Indaba (Zulu for “important matter”) for the South African NDT community to get together and air their needs, desires and raise the proverbial complaint concerning NDT RSA.

Radiation on Board

How important are those radiation warnings signs that must be displayed on vehicles transporting radioactive material? Let’s look at what will happen when both the technician and his assistant, who were travelling in the vehicle, are unconscious after being involved in an accident.
