Fabric Welding Machine The Equipment Is Simple And Flexible

First, the Fabric Welding Machine method:

1. Definition of Fabric Welding Machine:

The Fabric Welding Machine is a method of bonding the workpiece by heating or pressing, or both, and with or without the filling material.

In industrial production, Fabric Welding Machine is mainly used to connect metal materials, can also be connected to plastic, glass, ceramics and other non-metallic materials.

2. Classification of Fabric Welding Machine:

According to the Fabric Welding Machine principle, the type of heat source and the state of the parent metal, Fabric Welding Machine method can be divided into Fabric Welding Machine, Fabric Welding Machine of the brazing three categories.

(1) Fabric Welding Machine: Fabric Welding Machine process, the Fabric Welding Machine must be heated to the molten state, no pressure Fabric Welding Machine method.

Fabric Welding Machine is currently the most widely used Fabric Welding Machine methods, commonly used Fabric Welding Machine methods are electrode arc Fabric Welding Machine, submerged arc Fabric Welding Machine gas Fabric Welding Machine, non-melting gas Fabric Welding Machine and gas Fabric Welding Machine.

(2) pressure Fabric Welding Machine: Fabric Welding Machine process, must be applied to the Fabric Welding Machine pressure (heating or no heating) to complete the Fabric Welding Machine. There are two forms:

1) will be welded metal contact parts heated to plastic state, or local melting state, and then add a certain pressure, so that the metal atoms are combined with each other to form welded joints. Such as resistance Fabric Welding Machine, friction Fabric Welding Machine

2) Do not heat, apply only a large enough pressure on the weld surface of the welded metal, and make the atoms close to each other by means of plastic deformation caused by the pressure, so as to obtain a firm extrusion joint such as cold Fabric Welding Machine, ultrasonic Fabric Welding Machine, explosion Fabric Welding Machine The

(3) brazing: the use of metal materials than the melting point of metal materials for the brazing filler metal, the weldment and brazing filler metal heated to higher than the melting point of solder but lower than the melting point of the base metal temperature, the use of capillary action Wet base material, filled with joint gap and spread with the base metal, the method of connecting the weldment, known as brazing.

Can be: 1) soldering: melting point of less than 450 degrees of solder (lead, tin alloy-based) for Fabric Welding Machine, joint strength is low.

2) brazing: melting point higher than 450 degrees of solder (copper, silver-nickel alloy-based) for Fabric Welding Machine, joint strength is higher.

Second, the commonly used Fabric Welding Machine method:

1. Electrode Fabric Welding Machine of electrodes: Arc Fabric Welding Machine method for Fabric Welding Machine with electrodes by hand.

The high temperature generated by the arcs burning between the ends of the electrodes and the welds melts the coating, the wick and the weldment, and the gases and slag generated during the melting of the coating are not only free of the bath and the air around the arc, And the melting of the Fabric Welding Machine core, the base metal a series of reactions, so that the molten pool metal cooling crystallization to meet the requirements of the weld.

The Fabric Welding Machine material of the electrode arc Fabric Welding Machine is the Fabric Welding Machine electrode. The electrode is composed of two parts: the Fabric Welding Machine core and the medicine skin, and can be used as electrode and filling material.

Fabric Welding Machine Features:

1) The equipment is simple, flexible operation, can be indoors, outside and a variety of space position Fabric Welding Machine, can be more convenient for different forms of joints, short weld or tortured welds.

2) to control the shape of the more complex Fabric Welding Machine deformation.

3) the full range of electrodes, according to technical requirements matching with the base metal corresponding to the electrode.

Scope: can be welded carbon steel, low alloy just high strength structural steel, stainless steel and heat-resistant steel, can also be used for cast iron, aluminum, copper and its alloy Fabric Welding Machine. Fabric Welding Machine Fabric Welding Machine thickness is generally more than 3mm.

2. Gas protection arc Fabric Welding Machine: refers to the use of external gas as the arc medium, and to protect the arc, metal droplets, Fabric Welding Machine pool and Fabric Welding Machine high temperature area of the arc Fabric Welding Machine method. The addition of protective gas is argon, helium, carbon dioxide gas, argon and carbon dioxide mixed gas, Fabric Welding Machine material is wire. Gas shielded Fabric Welding Machine is arc Fabric Welding Machine, pool visibility is good, easy to operate, suitable for a variety of space position Fabric Welding Machine, is conducive to the realization of mechanization and automation.

2.1 TIG Fabric Welding Machine: the use of argon as a protective gas, a non-melting tungsten as the electrode, the weldment as the other electrode, through the tungsten and Fabric Welding Machine parts generated between the arc heating and melting of Fabric Welding Machine and filling metal , The formation of welded joints of an arc Fabric Welding Machine method (referred to as TIG Fabric Welding Machine).

Scope: suitable for Fabric Welding Machine chemical properties of lively metal, such as stainless steel, aluminum, titanium, magnesium and its alloys, for 0.5 ~ 5mm thickness of the thin plate or pipe within the various locations of Fabric Welding Machine, but also commonly used in the root of the pressure component Fabric Welding Machine The

2.2 Melting gas shielded Fabric Welding Machine: MIG Fabric Welding Machine with inert gas protection MIG Fabric Welding Machine, with active gas (CO2 Ar-CO2 mixed gas) to protect the molten gas shielded Fabric Welding Machine MAG Fabric Welding Machine, melting mixed gas Fabric Welding Machine, Welded wire gas shielded Fabric Welding Machine.

2.2.1. Carbon dioxide gas shielded Fabric Welding Machine: the use of current density than the electrode arc Fabric Welding Machine, wire Fabric Welding Machine speed is high, the Fabric Welding Machine process does not have to replace the Fabric Welding Machine wire, resulting in very little slag, the layers do not have slag, so the production efficiency is high; The sensitivity is not obvious; Fabric Welding Machine deformation is small, is conducive to sheet Fabric Welding Machine; automatic wire feeding, simple operation, easy to grasp the welder.

2.2.2. Mixed gas shielded Fabric Welding Machine: the use of O2 gas and CO2; Ar gas and CO2 gas; or O2 gas and Ar gas and CO2 gas mixture in different proportions of gas Fabric Welding Machine. Compared with pure CO2 gas shielded Fabric Welding Machine, it has the advantages of small Fabric Welding Machine splash, less burning of alloying elements, high weld quality and wide Fabric Welding Machine parameters.

2.2.3. Flux - cored wire CO2 gas shielded Fabric Welding Machine: Fabric Welding Machine method using flux - cored wire under CO2 gas protection.

A flux-cored wire: rolled into a round steel pipe or profiled steel pipe with a thin steel plate, filled with a certain amount of powder in the tube, drawn by the wire. Automatic Fabric Welding Machine process of the role of powder and the same electrode coating. The Fabric Welding Machine process of flux-cored wire gas shielded Fabric Welding Machine is combined with air residue protection.

B flux cored wire CO2 gas shielded Fabric Welding Machine, because the Fabric Welding Machine current flows only through the flux cored wire metal surface, the current density, Fabric Welding Machine depth corresponding to increase the melting speed than the same diameter of the solid wire high, the production efficiency is solid wire Of the 1.5 to 2 times the electrode arc Fabric Welding Machine 5 to 8 times. During the Fabric Welding Machine process, the arc is stable, the droplet is even, the splash is small, it is easy to slag, and the bead is beautiful. But compared with the solid wire CO2 gas shielded Fabric Welding Machine, Fabric Welding Machine smoke larger, more slag.
