7 things you might not know about welding

You may be surprised at how vast the profession is

First published date October 31 2014 Amended date February 19 2016

Before writing the guide, you could probably fit what we knew about welding on the back of a stamp. Fast forward a few weeks and we have become a melting pot of information about this sizzling profession. So before signing up to a course, why not sit back and take a look at the seven things you might not know about welding.


1. Explosive welding is one of the most powerful welding processes

This form of welding can accomplish what other welding methods can’t and can join nearly every kind of metal together, even the most highly dissimilar ones. 


2. Blacksmiths were some of the earliest welders

Until the end of the 19th Century the only welding process was forge welding. This is a solid state welding process that joins two pieces of metal together by heating them to a high temperature and hammering them together. This is one of the oldest forms of welding and has been used for centuries by blacksmiths.

3.The first welding robot was born in 1961

In 1961 General Motors installed the first industrial robot in history, named the Unimate. The Unimate came complete with a motorized arm, which weighed more than two tonnes, but allowed the robot to perform spot welds by following step-by-step commands.

4. The first welded road bridge was built in 1927

The first welded road bridge to be constructed was the Maurzyce Bridge in 1927, built across Sludwia near Lowicz, Poland.

5. You can weld underwater

This really baffled us, but it’s true! In fact the current world record for the deepest underwater dry weld was set by Global Industries in 1990, at 1075 feet deep. A dry weld is carried out underwater with a chamber sealed around the structure to be welded. Alternatively, a wet weld is a weld performed under the sea in open water. The wet welding record was set by the US Navy in 2005, at 2000 feet deep.

6. It really does get hot

The highest temperature of burning in welding is 5000⁰C, which is around the temperature of the surface of the Sun – you can see now why it’s imperative you wear protective clothing.

7. Metal can be expensive stuff

If you are welding the right sorts of metals, welding can be a lucrative business. For example, the most expensive metal ever made by man is Californium 252, which has an estimated value of $6,500,000 per gram. In fact at this moment in time there are no more than five grams of Californium 252 in the world. This wonder metal is used in medicine in the treatment of cancer, and in various industries checking welded joints. (Yes, we thought it looked a little underwhelming too).
