Introduction
Proper storage of welding consumables is often overlooked — but it directly affects welding quality, safety, and cost.
Incorrect storage can lead to:
Moisture absorption
Porosity an...
– FLUX–
Flux is a granular welding material. During welding, it can be melted to form slag and gas, which plays a protective and metallurgical role on the molten pool.
Constituent...
The thermal conductivity of copper and copper alloys is more than 5 times that of carbon steel. Welding is prone to pores, lack of fusion, and thermal cracks. The selection of welding wire direc...
The welding position is referred to when welding, the relative spatial position of the weld to the welder.
