Arc welding

SAW pipes
Submerged arc welding (SAW) is a common arc welding process.

Arc welding refers to arc supply heating energy, so that the workpiece to fuse together to achieve atomic indirect co-welding method. Arc welded is the most widely used welding method.

According to the statistics of the number of industrial countries, arc welding in the welding of total production in the proportion is generally above 60%.

The arc welding joints, with or without filler metal. When the electrodes used for the welding process, the molten wire, called the MIG arc welding, such as SMAW, submerged arc welding, gas shielded protect welding, tubular wire arc welding; with basic welding electrodes for welding process carbide or tungsten rod does not melt, called MIG arc welding, such as gas tungsten arc welding, plasma arc welding.

Depending on the characteristics of the process, the arc welding can be divided into electrode arc welding, submerged arc welding, gas shielded arc welding and plasma arc welding and so on.

Classification of arc welding

Arc welded can be divided into the three kinds of manual metal arc welding, submerged arc welding and gas shielded arc welding.

The biggest advantage of the hand-automatic welding equipment is simple, flexible, convenient, and applicable to a wide range of welding a variety of welding positions and straight seam girth and the various curves weld. Particularly suitable for operating the same occasion and short weld welding; automatic submerged arc welding with high productivity, weld quality is good, and good working conditions; gas shielded arc welding has a protective effect, stable arc, the heat concentrated.
