  • Three Areas of the Society that Needs Welding

    Welding is a manufacturing process in which several parts are joined together using heat and/or pressure. The process is usually applicable to metal parts as well as thermoplastics. There are many types of welding such as tig welding, mig welding, and arc welding to name a few. This manufacturing process is needed in almost all areas of the society. In this post, let’s just focus on the top three areas where welding is common and typical to use.

    Shipbuilding

    Ships should have a solid and watertight construction for safe operation and a long service life. Given the attention and complexity involved in a perfect shipbuilding process, the designers involved should have a high level of expertise in the field. As a result, the process can be very time-consuming and expensive. Also, some aspects of shipbuilding require significant submerged working hours, and this makes it difficult for humans to do the process manually.

    Arc welding for ships

    In arc welding, the metal electrode of a ship’s metal part is connected to an electrical power supply, creating a closed circuit when the electrode touches the sheet metal. Then an electric arc occurs when the electrode lifts a few millimeters from the plate after the electric current has jumped the gap. As a result, the base metal and the electrode metal melt and then both fuse. Arc welding can be automated through the use of robots, which makes shipbuilding easier.

    Example:

    • In 1982 the British Navy placed orders for the construction of ships with arc welding technology.
    • Despite the use of simple equipment, arc welding is very fast , which means that welding tasks can be carried out very easily and quickly. Also, it can work with AC (alternating current) or DC (direct current) power.
    • One of the disadvantages of arc welding is its unsuitability for welding thin metals. It also requires highly skilled welders.

    Urban water systems

    Urban water supply systems are typically exposed to a high volume of wastewater, which requires a robust construction that can withstand the resulting pressure .

    Metal inert gas welding for urban water systems

    Metal inert gas (MIG) welding is ideal for joining unalloyed stainless steel and aluminum with base metals. Given that these materials are strong and resistant to corrosion, they are suitable for building systems that are used to provide clean water for domestic and industrial use.

    Example:

    • The American Welding Society has approved metal inert gas welding as a safe and efficient technique for the construction and maintenance of various American water supply systems.
    • Gas-shielded metal welding is easy and simple and does not require any filler material.
    • The disadvantage is that MIG requires a lot of setup effort.

    Stunning works of art

    Some impressive works of art can be made by welding . This is especially true when it comes to metallic materials. Cutting hard metal parts into the shape and texture you want can be quite a chore. In some cases, the desired results cannot be achieved.

    Spot welding for works of art

    Spot welding or resistance spot welding is used to weld two or more sheets of metal into one by applying electrical heat and pressure. So if an artist wants to join two sheets of metal to create a work of art, this form of welding can be helpful.

    Example:

    • Some of the most famous welding artists use spot welding to create unique, strong, and super-attractive works of art. David Madero is one of those artists.
    • Spot welding is one of the most efficient and inexpensive welding techniques.
    • Areas joined by resistance spot welding can be weak if the current, pressure or heat used is insufficient.

    These are just a few of the uses of welding; the full list is longer.
