1. What is arc striking? What are the ways to start an arc? What should you pay attention to when striking an arc?
The process of igniting and producing a stable arc is called arc ignition. There...
Electrode arc welding is the most widely used welding method in industrial production. The metal to be welded is one pole, and the electrode is the other pole. When the two poles are close to each ...
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...
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...
