1. Technical essentials of argon tungsten arc welding
1.1 Selection of tungsten argon arc welding machine and power polarity
TIG can be divided into DC and AC pulses. DC pulse TIG is mainly used f...
Welding electrodes are metal wires with baked on chemical coatings. The rod is used to sustain the welding arc and to provide the filler metal required for the joint to be welded. The coating prote...
The preparation work before welding is as important as the welding process, which is directly related to the welding quality and effect of the finished product.

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 ma...
The energy source of brazing can be chemical reaction heat or indirect heat energy. It uses a metal with a melting point lower than that of the material to be welded as the solder. After heating, t...
The welding parameters of electrode arc welding mainly include electrode diameter, welding current, arc voltage, number of welding layers, power source type and polarity, etc.
