Welding is a very important role in the manufacturing industry, welding technology is also used in most industries, it is said that the welding technology has to talk about the difference between simple welding and chemical welding.

It can be directly attributed to the welding method of two categories, one is welding method, one is chemical welding method.

First in chemical welding method, in order to achieve the good of the welding process, the metal heating is accomplished by chemical reaction, but sometimes metal in welding need transform the temperature, and some require direct conversion value for the temperature of the liquid, then in such circumstances, in order to carry out the good welding completed, we must to some other simple work, and for welding welding is the direct welding materials welding, but welding welding is divided into many kinds of welding, such as welding, surfacing welding, argon arc welding and so on.

First, welding is one of the most common welding methods in modern technology, which may be considered as a simple one.

1, arc welding is most extensive, metal arc welding, regardless of the characteristics of manual weld or a flux of the automatic welding method are the welding material as the basis to welding, on some simple welding material or thin welding materials are the basis.

2, electric welding machine welding, in the modern welding industry occupies a very important position, especially in the production of large enterprises in the welding, for the production of welding, for the production of automobile manufacturing, welding, for the mechanical industry production welding, will use this common welding method.

Electric welding has been widely used in the industry of our country, the scope and scale of its application is expanding year by year,

Chemical welding method

1, forge welding is the welding of the oldest method of a, in welding, metal amount of forge flame heating to catch into plastic state, then beat and under pressure to complete the welding of heating part.

2. The welding method, welding and forging of a kind of transformation, with special torch to heat, is the state of the metal is heated to a temperature of shaping, and followed by compression or hammering method for welding work. This welding method is generally used in the railway track welding, as well as some of the important metal plate welding.

3. Gas welding, the welding is directly using the fuel gas welding, industrial pure oxygen combustion and the formation of a welding, first of all, the welding in the weld metal is heated to a temperature change to liquid or shaping of welding, and the welding is very common in technology. It is mainly used for casting welding and gas cutting, need to use the natural gas welding.
