What is Spot Welding/Resistance Welding?

Spot welding, also known as resistance welding, is a process of joining two or more metal sheets by passing a high electric current through them at a specific point of contact. The heat generated from this current melt the metal at the point of contact, which fuses the two metal sheets together. This process is widely used in the automotive, aerospace, and manufacturing industries for its efficiency, speed, and reliability.

Types of Resistance Welding

Resistance welding encompasses several types of welding techniques, such as spot welding, seam welding, projection welding, and flash welding. Each technique has its unique advantages and applications, but spot welding is the most common technique used in industrial applications.

Seam welding, also known as continuous welding, is used for welding long sheets or plates continuously. Projection welding is used for welding sheet metal parts that have raised or embossed features. Flash welding is used for welding large and complex structures such as aerospace components.

How Does Spot Welding Work?

Spot welding is a simple process that requires a power source, electrodes, and a workpiece. The electrodes clamp the metal sheets together and apply pressure to create a good contact between them. When the electric current passes through the electrodes, it generates heat at the point of contact, which melts the metal and fuses the sheets together. The amount of heat generated depends on the electrical resistance of the metal sheets, the size of the electrodes, and the amount of pressure applied.

Advantages of Spot Welding

Spot welding has several advantages over other welding techniques, such as:

Speed and Efficiency: Spot welding is a fast process that can join two metal sheets in a matter of seconds. It is an efficient process that can join multiple sheets simultaneously.

Cost-effective: Spot welding requires minimal equipment and can be done on a small scale, making it a cost-effective option for small businesses.

High Quality: Spot welding produces a strong and consistent weld, which is essential for applications that require high precision and accuracy.

Environmentally friendly: Spot welding produces minimal waste, making it an environmentally friendly option compared to other welding techniques.

Limitations of Resistance Spot Welding

While spot welding has several advantages, it also has some limitations, such as:

Limited Thickness: Spot welding is limited to metal sheets with a thickness of up to 3 mm. For thicker sheets, other welding techniques such as arc welding may be required.

Material Compatibility: Spot welding works best with materials that have similar electrical conductivity. Dissimilar materials may require additional preparation or a different welding technique.

Surface Preparation: Spot welding requires clean and flat surfaces for optimal performance. Any contamination or uneven surfaces can affect the quality of the weld.

In conclusion, spot welding is a widely used and efficient welding technique that is essential in the manufacturing industry. It offers several advantages, such as speed, efficiency, cost-effectiveness, high-quality results, and environmental friendliness. However, it also has some limitations that should be considered before using it for specific applications.

Advantages and Disadvantages of Structural Steel Fabrication

January 17, 2023 Editor

Structural Steel Fabrication is a complex process involving bending, cutting and designing of structures. Completion of the metal work requires expert hands as there is a lot fine workmanship needed to achieve the desired result. Structural steel fabrication is basically putting together pieces of steel which have pre-designed in the warehouse, hence it requires specific knowledge and experience to finish the work.

Advantages of Structural Steel

It is strong and is a lifetime investment. It is an excellent material for construction as strength of steel is greater than its density which makes it the most preferred material.
It is versatile material and give enough room for design. It can be bent, molded, cut and shaped with ease. Processing is simpler on structural steel as it is an alloy.
When compared with different types of metal, it is cost-effective and value for money.
Since it is built off-site, reduces accidents and any kind of mishaps during the construction process. At the same time, wastage is also minimized.
Above all, structural steel can be recycled without losing its inherent qualities, which makes it a sustainable material.
It does not require much time to complete structural steel fabrication work. Work is accomplished within stipulated period of time, unless some changes have been incorporated at the last minute.

Disadvantages of Structural Steel

If not processed properly, it can rust and crumble due to corrosion. It is very important to check if treatment has been done before beginning the fabrication work.
Both maintenance and the capital cost are high for structural steel.
There is a very high chance for crumbling of steel fabricated products if necessary steps are not taken to insure its longevity.
Steel is known for collapsing out of fatigue, so structures have to be stiffened properly by extra columns or as suggested by experts and engineers.
They need to be treated to stand tall and strong during fire and other natural calamities.

Structural steel has a huge market and metal manufacturers are bringing in use new technology for increasing the life and scope of structural steel fabrication work. The biggest advantage of the metal is it reduces carbon footprint, which is of top most importance at this point of our life and for saving the planet for future generations. Experts and engineers are continuously exploring its potential and making it stronger by the day. There are examples showing how structural steel has withstood time and is testimony to many stories of history.

Common Problems during Metal Plate Fabrication

Metal fabrication is a niche field and requires workmanship along with industry experience. Steel
fabrication as a process and a project is not an expensive thing, but resolution of even a small issue
can make the whole assignment costly and time-consuming. However, certain issues or if there is an
understanding of the subject, can be addressed upfront and avoided for the success of the end
product. Omni Steel Supply team has worked on several projects across the industry and some of the
real challenges which could have been pull-backs and could have increased the time-frame are—

• Communication—There are many tangible issues, but key to all is good communication
between the team members working on a project. Enterprise integration which is achievable
by seamless sharing of data about a project ensures success of each project in hand. When
experiences, work difficulties, project challenges, ideas, designs and client expectations are
shared with all the members, result is definitely going to be the best.
• Precision Planning—Project detailing, inclusive of workmanship for each stage is a nonnegotiable aspect. If planned to the core, it is easy to anticipate problems and it can be
handled before the issue really hits.

The above two problems are termed as stem issues, as they are the building blocks of any successful
and a quality end product. If a metal manufacturer is aware of these, half of the battle is won and
realization of the project within a given budget and time frame becomes a reality. Besides these, some
other problems that crop up during steel fabrication or customization could be,

• Scratches can be cause of concern, as external damage to metal sheet can lead to corrosion
and rust. This has to be avoided and should not be compromised in the process of reaching
the desired designs. Fabricators usually estimate such issues can take proper steps to protect
the sheet from any kind of external damages.
• Metal has strong flexibility and elasticity, sometimes it springs back after bending. Fabricators
ensure that a little more than the required needs to be done to achieve the required design
for the project. Bending, welding and punching are tricky process and should be handled with
utmost precision and diligence.
• Metal work is a game of temperature. The flow of heat varies with the type of metal and it
must be controlled in accordance to avoid any deformity. Metal fabrication is an art that
includes attention, detailing, planning and designing.
• Success of Structural Steel Fabrication projects is a lot dependent on the equipment. For
fabrication work, we need right type of equipment and workmanship to handle them. These
only can ensure clarity and high quality of the project.
