Structural steel is sustainable and reliable steel extensively used in construction sites. As compared to other metals, structural steel is cost-effective and light in weight. According to he welding professionals, there are 3 types of welding procedures used in structural steel industries. In this blog, we are going to discuss these 3 welding processes.
Drawn Arc Stud welding
Drawn Arc Stud welding or DASW is a common welding procedure widely used in structural steel fabrication industries. This is also known as stud welding which is quite similar to the flash welding. In this process, a fastener or stud is mainly welded onto the substrate or base metal. Fasteners generally come with several forms like unthreaded, threaded or tapped. According to the experts, a special type of flue known as ferrule is mainly used in this welding process. Apart from structural steel industries, this welding process is also used in the following areas:
Bridges, buildings & construction sites
Cable management
Food appliance industries like coffee makers, salad bars, griddles, etc.
Power distribution equipment plant
Shipbuilding & military applications
Moving vehicles in automotive, construction, trailers,
agriculture, etc.
Flux core arc welding
Flux core arc welding or FAW is another popular, portable and high-speed welding process used for structural steel applications. This is also known as metalcore welding. This is an automatic or semi-automatic welding technique ideal for structural steel, stainless steel, nickel-based alloy, etc. Flux core arc welding mainly requires constant voltage, flux, current and consumable electrode.
This arc welding has two different modes. First one is shield gas operation mode where the gas is mainly applied from an outer source & the second one is the self-shielding operation mode where the shielding gas is mainly produced during the decomposition of flux. In comparison to metal inert gas welding or MIG, flux core arc welding is very unique. This welding process is ideal for joining non-ferrous materials like Aluminium.
Stick welding
Last but not the least, SMAW or stick welding is a completely manual welding procedure in which a flux covered electrode (consumable) and electrical power source are generally required to weld two metals like steel. The current can either be AC or DC. SMAW is a cost-effective process widely used in structural steel industries. Many fabrication companies prefer SMAW because of its simple technique. Benefits of SMAW are
Portable and cost-effective.
Wide variety of metals, electrodes, welding positions and applicable.
Ideal for outdoor applications These three welding procedures are economical and widely used in structural steel fabrication industries. They are operated by the specialised and certified welding experts.
