Structures are built for various purposes, and staying is just one of them. Forming the best shapes out of the metals and solid building pieces is the duty of every construction team, and this would prolong depending on the amount of work every laborer or contractor is assigned. Many methods are being used to form the sealing material and the flawless structures; welding is the one that shapes up huge structures in many regions. It is also considered the most effective method of joining two vast pieces of a prefabricated structure. If you are a builder and have been doubtful of going ahead with welding options, you must know more about the various elements. Let us look at a few advantages and disadvantages of welding joints according to The Welding Pro.
Advantages of Welding Joints
- Since welding requires no holes, reduction of the area doesn’t happen. Load distribution would be more effective in this case. The structural members will remain strong and take the weight of the structure accordingly to transmit it evenly.
- The overall weight of the structure is significantly reduced as no connecting plates and gusseted plates are used in welding filler plates.
- Less labor and less material are required for welding joints, making it an economical option.
- Riveted joints are often preferred over welded joints, but this could be a foolish technical decision in certain structures. Welded joints are relatively more efficient than the former. Also, since riveted/butted joints are bulky, it may not be visually appealing. On the other hand, using welded joints will impart a more aesthetic beauty to the structure.
- Unlike the riveted joints, welding joints can be fabricated faster, meaning you can use them sooner.
- Through the welding process, complete rigid joints can be provided to make the structure firmer.
- Additions or alterations to the existing structure are easier than in the other common joints.
- The noise produced is also a lot less compared to riveted joints.
- Spaces for the joints can be made easily, regardless of the structure’s height or shape.
- A lesser workspace will do for welding compared to riveting.
Disadvantages of Welding Joints
- The fatigue strength is less in welding because these joints would be more brittle than the riveted joints.
- All members joined by welding may experience distortions that result in stresses due to the extreme heating and cooling processes.
- Electricity and skilled labor are indispensable in welding, meaning the expenses may increase depending on the size of the structure.
- The possibility of racks is high in welded joints because no space has been provided at the connecting points for contractions or expansions.
- Welding work inspections are more difficult and costlier than other types of joints.
- Certain defects such as slag inclusion, incomplete penetration, and internal air pocket cannot be detected easily in welded joints.
A fine balance lies between the advantages and disadvantages of welded joints. You have various reasons to opt for it in your project.
