We have always had a strong professional focus on welding performance for the best results; working with our customers to determine the best welding products to use in the right applications to achieve the best results, first time.

This Welding Assistance Resource Section is here to offer general welding advice and information to the wider welding community. 

Essential Factors in Gas Shielded Metal Arc Welding

Essential Factors in Gas Shielded Metal Arc Welding

Nowadays, gas shielded metal arc welding (GSMAW) is widely used in various constructions such as steel structures, bridges, autos, motorcycles, construction machinery, ships, offshore structures, pressure vessels, and pipelines due to high welding efficiency.

How to calculate welding consumption

We recommend you to use the following diagrams for a quick estimation of the consumption of welding consumables for welding ferritic steel butt joints and fillet joints respectively.

Please follow the examples indicated by gray arrows in the figures.

What is heat input, and how does it affect the quality of welds?

Heat input can be referred to as "the electrical energy supplied by the welding arc to the workpiece."

In practice, however, heat input can approximately ― if the arc efficiency is not taken into consideration ― be characterised as the ratio of the arc power supplied to the electrode to the arc travel speed, as shown in the following equation.

Metal Cored Wires vs Solid Wire

"I've always used solid wire - works fine, does the job. Why change?"

A typical comment we often hear, however… Change is definitely worth thinking about!

Depending on the application, using metal cored wire (MCW) can generate significant cost savings in conventional gas metal arc welding (GMAW) processes. It is ideal for robotic welding but is also suitable for so much more.

Advantages of Downhill Welding

What advantages are there in downhill welding and how should it be used, compared with uphill welding in GMAW and FCAW?

As you may know, we use either downhill or uphill welding in the vertical position. Downhill welding is carried out with a downward progression, conversely, uphill moves in an upward progression. Downhill welding is often used for fillet welding of steel sheets due to the following advantages over uphill welding.

Design of Structural Fillet Welds

Fillet Weld Legs Determine Size and Throat of Fillet Welds 

In heavy machinery, ships, and buildings, extensive frameworks and intricate angles may be composed of many kilometres of welded joints. Among them, fillet welds are used to join corners, Ts. and lap joints because they are more economical than groove welds. That is, fillet welded joints are simple to prepare from the standpoint of edge preparation and fit-up.

How to achieve welding efficiency

The biggest gains for your business can be made by improving welding operator efficiency to reduce your single biggest cost - labour.
