Common welding processes
Welding is a widely used process in our life. It may be used for maintenance or some metal castings. We are familiar with the electromechanical industry, and welding is an indispensable technology in the electromechanical field. In the past, we may only use the welding gun and then apply the original welding method. With the continuous development of society, the welding methods are also changing. The welding equipment such as energy storage stud welder has also been put into use in the market. Many people may not know much about welding methods. Let's learn about the common welding process - manual arc welding.
Manual arc welding is a kind of welding method which developed earlier and is still widely used at present. The welding rod coated on the outside is used as the filler metal, and the arc burns between the end of the welding rod and the surface of the workpiece to be welded. Under the action of arc heat, on the one hand, the coating can produce gas to protect the arc, on the other hand, it can produce slag to cover the surface of the molten pool to prevent the interaction between the molten metal and the surrounding gas. The more important role of slag is to produce physical and chemical reaction with molten metal or add alloy elements to improve the properties of weld metal. Manual arc welding equipment is simple, light and flexible. It can be applied to the welding of short joints in maintenance and assembly, especially for the welding of parts that are difficult to reach. Manual arc welding with corresponding electrodes can be applied to most industrial carbon steel, stainless steel, cast iron, copper, aluminum, nickel and their alloys.
The content of manual arc welding is introduced here. I hope it can be helpful to you. However, Xiaobian should also remind you to take protective measures when welding to avoid hurting yourself. In addition, welding equipment should also be maintained regularly, which can prolong their service life.
