Description

TECHNICAL FIELD

[0001] The utility model relates to welding fixture technical field, concretely is a kind of fixed clamp for steel welding. BACKGROUND

[0002] Welding, also known as soldering, is a manufacturing process and technique that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many energy sources for modern welding, including gas flame, electric arc, laser, electron beam, friction and ultrasonic wave, etc. In addition to being used in factories, welding can also be performed in various environments, such as outdoors, underwater and in space. No matter where, welding can pose a risk to the operator, so appropriate protective measures must be taken when welding. The injuries that welding can cause to the human body include burns, electric shock, vision impairment, inhalation of toxic gases, excessive ultraviolet radiation, etc. During the welding process, the workpiece and filler metal melt to form a molten area, and the molten pool cools and solidifies to form a connection between the materials. During this process, pressure is usually applied. There are many energy sources for welding, including gas flame, electric arc, laser, electron beam, friction and ultrasonic wave, etc. Metal welding is divided into three categories according to the characteristics of the process: fusion welding, pressure welding and brazing. In the process of fusion welding, if the atmosphere directly contacts the high-temperature molten pool, the oxygen in the atmosphere will oxidize the metal and various alloying elements. Nitrogen, water vapor and other gases in the atmosphere entering the molten pool can also form pores, slag inclusions and cracks in the weld during the subsequent cooling process, which can deteriorate the quality and performance of the weld.

[0003] In order to improve the quality of welding, people have developed various protection methods. For example, gas shielded arc welding uses argon, carbon dioxide and other gases to isolate the atmosphere to protect the electric arc and molten pool during welding; another example is that when welding steel, titanium iron powder with high affinity for oxygen is added to the coating of the welding rod to deoxidize, which can protect the beneficial elements manganese and silicon in the welding rod from being oxidized and entering the molten pool, and after cooling, a high-quality weld is obtained. Steel welding belongs to metal welding, and if the hand holding is not stable enough, a fixed clamp is needed for positioning. The existing fixed clamp for steel welding cannot perform rotary welding, and needs to wait for one side to be welded before disassembling and replacing the other side, which affects the welding efficiency.
