Suspended Spot Welding Machines is used for many of the joining processes involving metals. There are many applications for these types of machines. The basic difference between a suspended and stand mounted Welding machine is in the location of the arc or torch. The spot welder welds by placing a welding rod into a welder gun and a piece of metal is held between the rod and the tip of the welder.
High efficiency thermal expansion welding torches with tungsten electrodes. It is used with a variety of steels. A flexible non-flammable plug is supplied with most units. Simple to use and easy to install, saves valuable energy. Stand mounted type nimble, 360 and portable variety welds easily. Stands at any angle and any place.
The high pressure sodium lights used in Suspended Spot Welding Machines come in a variety of colors. It uses a floating light element which makes the weld faster. The gas supply port is located above the base. Most units have the option of switching on or off the gas supply to the welding torches. The tungsten electrodes are made of both argon and tungsten.
It uses three types of welding electrodes – the tungsten electrode, the normal wire and the normal spark plug. In addition to the welding electrodes there is a gas tank which holds the welding gases. The welding torch is provided with an adjustable pressure relief, which makes it easier to start welding at different work temps.
The equipment has the ability to monitor the weld puddle and monitor the weld time. Weld puddles are crucial because the first weld will have a lower quality than all other welds. The process is also called as the pigtail or tubular arc Welding (T WAW).
Tasks include preheating the welding torches, clamping, welding. Suspended Spot Welding is the most versatile form of arc welding and the most common in industrial settings. The machine works best in metals that are malleable and ductile such as stainless steel and aluminum. It can also weld thinner materials such as copper or brass. Tasks include spot leveling, elimination of back feed and cleaning torch.
The most common way to weld is the combined method in which the welders simultaneously weld the two metals by forming a hot arc. The hot arc and the gas are stored in separate tanks. There is no need to maintain the gasses. The method requires fewer operators because less welding needs to take place and therefore offers lower pay grade and flexible working hours for operators.
The welders use one or more electrodes and work with an automatic welding machine. The typical weld process starts by increasing the preheating temperature of the welding torches, while lowering the tungsten electrodes as the work progresses. The work is then Continued by dipping the torch into the molten flux and joining the welded pieces.
The welding torches are usually either shielded gas welding or consumable gas welding and come in different wattage, amperage and voltage requirements. Welding torches are used to create both hot and cold arc welding. The biggest advantage of shielded welding torches is that there is no ongoing maintenance required. This is because there is no need for oxygen for the welds. This makes it possible to use standard oxygen tank or Oxygen gas canisters that are commonly used in welding operations.
