Suspended Spot Welding is a technique used in place of standing welds. There are pros and cons to both, and you will have to consider your weld shop and your specific needs when making your decision. Standing welds can be difficult to work with, are not as stable as a suspended weld, and create more heat on the welding gun. If you have large, heavy pieces that you need to weld, then standing welds may be your best option. Here is how it works.
The first difference between a stand mounted and suspended welding process is in the placement of the torch or arc. When working with larger pieces, like sheets or panels, it is often necessary to have a constant current to prevent overheating. The constant current usually comes from an external source such as a battery or can come from a smaller transformer. A smaller transformer is usually a better option because it can be placed closer to the work area, which means that less wire needs to be run to reach the current. When using a stand mounted welder, the wire is run through the welder directly and this means that more wire is exposed to the current, which can cause overheating. Another con of using a stand mounted welder is that the power cord is often far too long for smaller welder jobs.
The second difference is found with the actual process of welding itself. Stand welders typically have a single torch and a weld puddle is created using a single wire. This allows for a much higher welding efficiency but also means that it takes a longer amount of time to complete a weld. The reason this occurs is because the weld puddle is not completely enclosed. Most welding controllers are equipped with an automatic calibration system that allows the operator to determine what setting the welding is at and then increase or decrease the temperature of the weld puddle in order to increase the overall weld quality.
There are a number of different types of automatic welders on the market today. Each has a different way of sensing the welding parameters and using them to control the arc voltage. Some of these different types include gas-fuel initiated arc, thermal initiation, piezoelectric weld, and solenoid based weld automation systems. While each has a unique set of benefits, there are a few common points that most of them share.
One of the benefits of using modern welding equipment is the fact that it can incorporate many different types of automation into one package. The automatic welding equipment market today includes things like wire feeders, plasma cutters, and even welded welding machines. Because of this wide array of features, it is important that the welder that a company is considering purchasing has the right functionality. Many companies have welded equipment that can be run without any human supervision, but the weld process will still be controlled completely by the computer. This is ideal for companies that do not have many different types of welders on hand and are fine tuning one.
One thing that all Suspended Spot Welding machines have in common is that they all have the ability to handle both flux cored and non-flux cored wires. The way that this works is that the wires that are being welded are placed in a reservoir that is filled with tungsten gas. When the welder starts up the machine, the gas flows through the pipe at the tip of the weld. Once the welder begins to actively weld, the tungsten begins to heat up and gets pulled down the pipe. The tungsten provides a consistent arc that is very stable and reliable for any welder to work with.
