1. Core principle: Why must we use argon?
During the welding process, the metal is like red-hot iron at high temperatures. If it is not protected, it will immediately combine with the oxygen and ...
One of the most frustrating moments for a beginner welder is striking an arc only to have the electrode stick to the workpiece. It sticks, glows red, and you scramble to twist it free. Don’t worry...
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...
The welding electrode is a metal rod that is melted and filled at the joint of the welding work-piece during gas welding or electric welding. The material of the electrode is usually the same as th...
The welding electrodes that leave the factory have been dried at high temperature and packaged with moisture-proof material, which usually prevents the coating from absorbing moisture. However, dur...
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...
