20 Jan Gas Metal Arc Welding and Weld Head Usage
If you are in the welding business, then you have probably heard of Gas Metal Arc Welding. This is an automatic or semi automatic welding process that has been around for almost one hundred years. If you are using an orbital welder, then it is necessary to make sure you have a weld head or a large supply of these weld head in order to meet the demand of your machine. If you perform proper maintenance, then your orbital welder should perform optimally. One popular welding method that is implemented with the orbital welder is the gas metal arc welding method.
The gas metal arc welding method uses a shielding gas and a continuous, consumable wire electrode that is fed through a welding gun. The gas metal arc welding method uses a constant power source such as voltage or a direct current to weld together materials such as steel and aluminum. The gas metal arc welding method is most popular in industries such as car manufacturing due to its versatility and immense speed compared to other methods.
The gas metal arc welding method is also widely used by the sheet metal industry. By using arc spot welding, there is no more need for resistance or rivet welding anymore. The gas metal arc welding method is also used in robot welding. In this process, robots operate the welding fun and the sheet metal. This helps save even more on time and costs. The gas metal arc welding method is not usually suitable for outdoor use because changes in the atmosphere can cause the shielding gas to dissipate. If this happens and the shielding gas dissipates, then the quality of the weld will be inferior compared to what it could have been. The gas metal arc welding method is also unsuitable for underwater welding.
The equipment needed for the gas metal arc welding process is a welding gun, a wire feed unit, a shielding gas supply, and an electrode wire. When the control switch is turned on, the electrical power and gas flow are initiated. This causes an electric arc to be struck. The gas nozzle’s main purpose is to direct the welding gas evenly into the welding zone.
As you can see, the gas metal arc welding process is fairly complicated. Despite this thorough process, it is relatively simple to implement once you have the proper tools. If you need a new weld head, then your best chance is to look for one available online.
