Manual arc welding
Arc welding fusion welding in the welding method. It is also in all kinds of welding methods most widely used welding method, which the simplest most common is use manual welding for welding electric arc welding, known as the manual arc welding, referred to as manual arc welding. Hand arc welding equipment is simple, convenient and flexible operation, strong adaptability. It is suitable for welding of all kinds of metal materials and all kinds of shapes and structures, especially suitabl
Manual arc welding method
1)Linear strip method. Linear transport method is often used to weld groove. The butt of the first layer or multi-layer welding bead welding. 2)Linear reciprocating strip method. Such method is characterized in that the welding speed, weld is narrow, fast heat dissipation, applicable to sheet or joint gap larger multilayer welding of first layer bead. 3)Saw tooth movement. Welding, welding rod end as saw tooth shaped continuous swing and move forward, and pause for a mo
Working principle of plasma cutting machine
Plasma is heated to a high temperature and is highly ionized gas, it will arc power will be transferred to the workpiece, high heat to melting of a workpiece and disallowed, the formation of plasma arc cutting working condition. The compressed air into the chamber after the torch distribution is formed two plasma gas and auxiliary gas. Gas plasma arc melting metal, various components and auxiliary gas cooling torch and the molten metal has been blown off. Cutting power
What are the advantages of gas shielded arc welding
Compared with other welding methods, gas shielded arc welding has the following characteristics: (1)The arc and weld pool are in good visibility, and the welding parameters can be adjusted according to the welding pool. Gas shielded welding machine. (2)The welding process is easy to operate, with little or no slag slag after welding, basically cast without slag. (3)In the compression of the gas flow, the arc heat is concentrated, the welding speed is fast, the
