Spot Welding
Spot Welding Services at Affordable Prices
Our spot welders are useful when an object needs to be welded within a restricted space or when there are complicated obstacles like cables or even rivets. Coaxial Impact Hammer pushes down at a sufficient force to bind two materials in a way, but unlike other welding methods, it is less invasive and is less apparent when it is used.
What are the signs to tell if you require TIG or Mig welding? What will the various types of welding look like once they’re done? What is the best time to look into spot welding? The good thing is that the team at Mascot Steel will answer any questions you might have and ensure that the project is completed according to your requirements.

What is the Spot Welding Process?
A machine makes use of compressed air to direct arcing on two different materials at high speed (obtaining temperatures as high as 5000 degrees F). After this is done the hammer strikes down on two different materials so that the two surfaces are pushed to join. In order to have a reliable welding process, it's essential to select the correct weld bead to suit your particular project.
Two-shaped electrodes of copper alloy are used to focus welding current into a tiny "spot" while also clamping the sheets. The workpieces are held together by the pressure of electrodes until they achieve an ideal shape.
Spot welding is a process that involves three steps. The first step is when the electrodes are positioned on the metal's surface, and a tiny quantity of pressure is applied. After that, current from the electrodes flows through for a few seconds before being removed. However, they remain in place as the metal cools. The time to weld is contingent on the different thicknesses of the metals as well as electrode forcefulness and diameter capacity.
Spot Welding Applications
Spot welding is a fantastic method of welding thinner sheets of sheet metal wire mesh that has been welded or wire mesh that is regular. If the material gets too large, it will be more difficult to spot weld since the heat can move into and impact the surrounding areas more quickly. A lot of items made from sheet metal, such as buckets, feature spot welding. Aluminium alloys are able to be spot-welded, but their superior electrical and thermal conductivity demands more welding power. The most expensive and robust welding transformers are required to accomplish this.
In the automotive industry spot welding is often used to join sheet metal, and to make the frame of a car. Apart from being automated and industrial robots, a lot of the machines used in factories are spot welding machines.
Is Spot Welding Stronger Than MIG Welding?
But when it comes to handling heavy stresses or loads spot welding could be a bit less effective compared with MIG welds. However, a competent Spot Welder Operator who uses the proper Welding parameters and Spot Welding techniques can help to alleviate this problem. Making use of modern Welding Machines along with Tungsten Electrodes also allows for greater control over the process, which can reduce the possibility of weld defects.
A crucial thing to bear in mind is that spot welds could be unable to work with heavier materials due to their higher resistance to heat. However, advanced techniques such as Welding Robots and cutting-edge Spot Welding Equipment have been successful in overcoming this problem.
A systematic method of Welding Safety that includes the proper Fume Extraction system and a thorough Weld Inspection, can increase the reliability and quality of spot welding. Additionally, a thorough Welding Course lets you be proficient at spot welding. It is a complex process that requires a precise balance of current, pressure and time.
It is also important to be aware that the field of welding extends beyond spot welding and includes various other methods such as Soldering, Brazing and Projection Welding, along with Seam Welding. Regardless of the differences in Weld Strength, every welding technique, which includes spot welding and spot welding, has its own distinct strengths and functions.
