Welding can use AC or DC welding machine. When using a DC welding machine, there are positive connection and reverse connection. Factors such as the electrode used, the condition of the construction equipment, and the welding quality should be considered. Compared with AC power supply, DC power s...Read more »

Argon tungsten arc welding uses argon as a shielding gas to heat and melt the welding material itself (it is also melted when the filler metal is added) by means of the arc generated between the tungsten electrode and the weld body, and then forms the welding of the weld metal Way. The tungsten e...Read more »

What is flux-cored arc welding? Flux-cored wire arc welding is a welding method that uses the arc between flux-cored wire and workpiece to heat, and its English name is simply FCAW. Under the action of arc heat, welding wire metal and workpiece are connected by melting, forming a weld pool, arc f...Read more »

When welding stainless steel, the performance of the electrode must match the purpose of the stainless steel. Stainless steel electrode must be selected according to the base metal and working conditions (including working temperature, contact medium, etc.). Four types of stainless steel as well ...Read more »

Welding is a process in which the materials of the workpieces to be welded (the same or different) are combined by heating or pressure or both, and with or without filling materials, so that the materials of the workpieces are bonded between atoms to form a connection. So what are the key points...Read more »
