During fusion welding, under the action of the welding heat source, the liquid metal part with a certain geometric shape formed on the weldment by the molten electrode metal and the partially molte...
Stick Welding Process Intro
SMAW (Shielded Metal Arc Welding) is often called stick welding. It is one of the most popular welding processes used today. Its popularity is due to the versatility...
Harmful factors of welding materials
(1) The main research object of welding labor hygiene is fusion welding, and among them, the labor hygiene problems of open arc welding are the biggest, and th...
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 constructio...
Consider the physical properties, mechanical properties and chemical composition of the weld material
1. Structural steel welding, generally consider the principle of equal strength, choose to me...
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...
