Readings
The troubled history of vocational education
Welding technology has evolved over centuries, and it’s difficult to credit a single person with advancing it because they each played a role in the “gales of innovation” described by Joseph Schumpeter. Here are a few notable individuals:
- Sir Humphry Davy (1778-1829): Davy, an English chemist and inventor, is often credited with the discovery of the electric arc, a critical development in welding technology. His work laid the foundation for many modern welding processes.
- Elihu Thomson (1853-1937): Thomson, an American engineer and inventor, made substantial contributions to electric welding technology. He improved the design of welding machines and was a pioneer in developing the resistance welding process.
- Nikolay Benardos (1842-1905): A Russian inventor and engineer, Benardos is often credited with patenting one of the first arc welding methods using carbon electrodes. His work helped popularize arc welding as a practical joining method.
- C.L. Coffin (1877-1959): Coffin, an American engineer, played a crucial role in the development of the submerged arc welding process. This method is still widely used in heavy industry for its high deposition rates.
- Charles Picard and Auguste De Meritens: These two inventors are credited with developing the first successful welding process using a consumable electrode, known as metal-arc welding. Their work laid the foundation for modern stick welding.
- Carl Wilhelm Siemens (1823-1883): Siemens, a German engineer, made significant contributions to the development of gas welding. His work with gas flames laid the groundwork for the oxyfuel welding and cutting processes that became essential in industry.
- Percy Spencer (1894-1970): Spencer, an American engineer, accidentally discovered microwave heating while working with radar equipment during World War II. His discovery indirectly contributed to the development of microwave welding techniques.
These individuals are the first names that collectively advanced welding technology.

Determining Strength of Corroded Pipelines
Massachusetts Institute of Technology
As cities-within-cities many colleges and universities own and maintain at least 10 miles — and possibly up to 1000 miles — of underground piping for water, steam and natural gas; much of it under pressure within buildings or in outside, underground tunnels. The American Society of Mechanical Engineers develops a suite of standards for these, and many other piping systems:
ASME B31 Piping System Standards
Fluids running under pressure are a significant infrastructure hazard in educational and all communities
ASME has released a redline of B31 Manual for Determining the Remaining Strength of Corroded Pipelines for public comment:
ANSI Standards Action Pages 137 – 139
ASME often posts its redlines in ANSI Standards Action as well as on its standard development platform:
This document is intended solely for the purpose of providing guidance in the evaluation of metal loss in pressurized pipelines and piping systems.
Comments are due July 26th.
You may send comments (with optional copy to psa@ansi.org) to: Ray Rahaman, rahamanr@asme.org
The ASME consensus product line is on the standing agenda of our periodic Mechanical, Energy and Nota Bene teleconferences. See our CALENDAR for the next online meeting; open to everyone.

Water 100
“At the Water Trough” 1876 J. Alden Weir
“A flood is nature’s way of telling you
that you live in the wrong place.”
— Some guy
Water standards make up a large catalog and it will take most of 2023 to untangle the titles, the topics, proposals, rebuttals and resolutions. When you read our claim that since 1993 we have created a new academic discipline we would present the best practice literature of the world’s water standards as just one example.
The Water 100 session takes an aerial view of relevant standards developers, their catalogs and revision schedules.
The Water 200 session we examine the literature for best practice inside buildings; premise water supply for food preparation, sanitation and energy systems.
The Water 300 session reviews standards covering athletic facilities such as swimming pools, therapeutic tubs, ice rinks and the like.
The Water 400 session will run through best practice catalogs of water management outside buildings, including interaction with regional water management systems.
The Water 500 session is a study of case histories, disasters, legal action related to non-conformance. Innovation.
