Welding 101

Welding is a very important aspect of engineering and manufacturing. Without this ability, strong and durable connections between materials would not be possible. Thus making it hard to produce many different items that we rely on in our everyday lives, some examples being medical implants and electrical devices. This is why we have put together some welding Birmingham tips.

Welding

Welding is the key focus of steel fabrication.

The parts that have been formed and machine will then be assembled and tack welded into place and then checked again for accuracy. It is possible a fixture may need to be used to locate the parts for welding if multiple weldments have been ordered.

The welder will then continue to finish the welding against the engineering drawing if the welding is has a detailed plan, or against their own judgment on the chance no details have been given.

Precautions may need to be taken to prevent any warping of the weldment due to the heat. It may call for a re-design of the weldment to use less weld, welding in a staggered fashion, using a stout fixture, covering the weldment in sand during cooling, and the straightening operations once done welding.

The straightening of steel weldments that have warped would be done with an Oxy-acetylene torch; heat would be applied to the steel in a linear sweep in a slow motion. The steel should have a net contraction, once cooled, following the direction of the sweep.

Welding: a history

The method of welding is the practice of using heat to join materials together, using equipment that utilises open flame, an electric arc or laser light.

Middle Ages – The Bronze Age is the earliest evidence of welding that can be traced back.
An early example was the welding of gold boxes that belonged to the Bronze Age, the Egyptians had also apparently learnt the art of welding – several of their iron tools were made using the joining method.

1800 – A milestone in the history of welding was the use of open flames (acetylene) as it allowed the manufacture of intricate metal tools and equipments.
The discovery of acetylene was made in 1836 by an Englishman named Edmund Davy; acetylene was since utilised by the welding industry.
Another tool that was used extensively in welding metals was that of a battery operated tool which could produce an arc between carbon electrodes, invented by Sir Humphrey Davy.

1880 – In 1881, Auguste De Meritens, a French scientist succeeded in fusing lead plates by using the heat generated from an arc.
Later an electrode holder was manufactured by Russian scientist Nikolai N. Benardos and his compatriot Stanislaus Olszewski.

1890 – The 1890’s popular method of welding was carbon arc welding.

1900 – Strohmanger first introduced coated metal electrode in 1900, to help with the stability of the arc, a coating of lime would have been applied.
More welding methods would have been developed during this time, including seam welding, spot welding, flash but welding, and projection welding.

1920 – This was the first introduction of automatic welding, specifically used for repairing and molding metals.

1930 – The development of stud welding was in this time period by the New York Navy Yard.
Stud welding was increasingly used for shipbuilding and the general construction industry,

1950 – The CO2 welding process had become popularised by Lyubavskii and Novoshilov in 1953, becoming a part of the process of choice for welding steels.

1960 – Advancements in the 1960s saw dual shield welding, inner shield, and Electroslag welding were among the most important developments in that decade.

Most Recent – The most recent developments in the welding industry include the friction welding process developed in Russia and laser welding.
