ESAB Knowledge Center

Since Oscar Kjellberg's invention of the covered welding electrode in 1904, ESAB has played an integral part in the discovery and development of more commonly accepted welding processes than any other company.

ESAB's Knowledge Center contains a vast amount of information for the welder, the engineer, the welding inspector and the project manager.

An Introduction to Welding Inspection

Many characteristics of a weld can be evaluated during welding inspection, some relating to the welds size, and others relating to the presence of weld discontinuities. The size of a weld can be extremely important, as it can often relate directly to the weld's strength and associated performance, undersized weld's may not withstand stresses applied during service. Weld discontinuities can also be important. These are imperfections within or adjacent to the weld, which may or may not, dependent on their size and/or location, prevent the weld from meeting its intended performance. Typically these discontinuities, when of unacceptable size or location, are referred to as welding defects, and can ...

Filler Alloy Selection For Aluminum Welding

When considering the welding of aluminum alloys, and the development and qualification of welding procedures one of the main considerations must be that of filler alloy selection. Typically there are a variety of filler alloys available which may be used to join any given base alloy. However, there are a number of variables associated with the selection of the most suitable filler alloy to be used for any base alloy or alloy combination. In some cases, we may find ourselves in a trade off situation, where we are required to choose between different characteristics of the completed weld in order of importance.

Some considerations for the selection of a filler alloy are typically ease of ...

Is there a filler alloy that can be used to weld all aluminum base alloys?

Q - I work in a small welding repair shop, and I am often asked to perform repair welding on aluminum structures. Sometimes the type of base alloy is known, and on other occasions, it is not. I have two questions relating to the repair of aluminum.

First, is there a filler alloy that can be used to successfully weld all types of aluminum alloys? And secondly, from time to time, I come into contact with two aluminum alloys of which I have found difficulty in obtaining information about arc welding. These alloys are 2024 and 7075. Can you provide me with information on how to weld these alloys with either the GMAW or GTAW process?

A - In covering your first question first, the short ...

Should I use 4043 or 5356 filler alloy?

As a basic description we can say that 4043 is an aluminum filler alloy with 5% silicon added and that 5356 is an aluminum filler alloy with 5% magnesium added.

There are some misconceptions within the industry that you can successfully weld any aluminum base alloy with either 4043 or 5356 filler alloy. I must start by saying that this is not the case. However, there are many common structural aluminum base alloys that can be welded with either 4043 or 5356. One such alloy is 6061.

The question here is when should we choose one of these filler alloys over the other?

When the filler alloy selection chart allows the use of either 4043 or 5356 as filler for a specific base alloy, ...
