Welded steel structures can be easily referred to as the modern spine of architecture. Many buildings, facilities, and city landscape structures are now made with steel elements that are durable and sustainable to damages. The endurance here is not, however, reliant solely on the type of steel used – it’s even more so about the strength and durability of welds that hold the structure together. Welding is, as a part of a steel structure, constantly put under pressure and fatigue and it can, easier than the structure itself, give into failures. This is why it is more than necessary to see steel architecture welding for what it actually is and take all the forces it will be exposed to into consideration when planning any steel structure welding.
The different types of steel structure welding
Choosing the best welding process and filler metal for welding structural steel is key to creating a long-lasting, well-held construction. Welding can take place both indoors and outdoors, so one of the first factors that need to be considered while choosing the best welding method is the environment that the work will be done at. If it’s outside, it’s probably best to watch out for wind – the enemy of shielding gas and the welding processes that rely on it.

Stick welding and self-shielded flux-cored arc welding are the two processes that are most commonly used for structural steel welding done in the field, while gas-shielded flux-cored arc welding and submerged arc welding are used for indoor steel structure welding. The gas-shielded flux-cored arc welding has become in the recent years a much popular method than the MIG welding, that was widely used only a couple of years ago. Fabricators should consider all pros and cons of these welding methods and choose the best-suited option for their application. They have to remember that with all those methods there comes the portability of the welding appliances, which is in some cases much harder than in others.
Steel structure welding challenged by fast-paced industries
There is a challenge for the steel construction welding industry, as the welders must now meet all the welding standards on top of keeping their work as quickly as possible. More and more constructors rely on prefabricated steel constructions as much as possible to cut on time that it takes to weld it all together on-site. Can the welding community keep up with the tempo? With all the new technology that comes into play, it seems they may just do so.
