Welding Articles

Sustainability is a word on everyone's lips at the moment. Climate change, plastic waste, carbon footprint—are conversations taking place in our personal and professional lives.

We cover why it's important to control welding gas flow rate and the best way to optimise and economise welding gas consumption.

Have you ever stopped to consider how much time is spent managing your welding gas cylinders?

We look at how travel speed affects weld quality and efficiency, and the important role that welding gas can play.

This article looks at simplifying the task of optimising your welding application.

Spatter is made up of many thousands of droplets of molten filler metal that escape from the weld pool and are scattered around the work area during welding. These small, round balls of molten metal can fall on the welder, workpiece, the floor and surrounds.

There are numerous national and international regulations covering the safe operation of welding and cutting systems. Find out how to work safely when arc welding.

Cylinders are heavy and awkward to handle. Frequent lifting and handling can cause back injuries and upper limp disorders. There are some simple rules to follow to avoid injury.

Gas cylinders are large, heavy and relatively unstable due to the small base-diameter to height ratio. There are a few simple rules to follow to ensure on-site safety.

Find out how to work safely with gas cylinders.

Drive safely, arrive safely. There are some basic rules to follow when transporting cylinders.

Weld distortion or deformation can occur as a result of the non-uniform expansion and contraction of the weld and base metal during the heating and cooling cycle.

Porosity is caused by absorption of gas in the weld pool that is released as solidification takes place and becomes trapped in the weld.

Steam engines and mechanisation in the late 18th century brought us the industrial revolution.

The UK media frequently report about the skills shortage in engineering and healthcare, however, the shortage of welders is not so prominent in the headlines.

There are more than 16,000 companies in the building construction industry in UK and Ireland* and, therefore, a significant segment for Air Products welding gases.

For over 15 years, Air Products has supplied MDF Engineering, Antrim, with a wide range of quality industrial gases for its cutting and welding processes.

Porosity can be a significant problem when welding aluminium, caused predominantly by the absorption of hydrogen in the weld pool, which forms pores in the solidifying weld metal.

"See the bigger picture" is the message that Air Products is advocating to promote its Maxx® weld process gases range.

Quality defects have significant costs associated with them, such as money, time, resources and, if not ultimately resolved, customer satisfaction.

Welding generates fumes and gases that, if inhaled, can be harmful to health.

A uniform flow of gas is needed to shield the molten metal by blanketing it properly to avoid atmospheric contamination, which can lead to increased levels of oxidation or even porosity of the finished weld.

British Cycling, under the guidance of Sir Dave Brailsford, have been incredibly successful. But what's the link with welding? The concept is just as applicable in fabrication—small changes all add up.
