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 ...
The coating plays a complex metallurgical reaction and physical and chemical changes in the welding process, which basically overcomes the problems in the welding of the photo electrode, so the coa...
– 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...
Spot welding is a resistance welding method in which the weldment is assembled into a lap joint and pressed between two electrodes, and the base metal is melted by resistance heat to form a solder ...
ER70S‑6 conforms to AWS A5.18. The designation breaks down as follows:
ER – Electrode or filler rod
70 – Minimum tensile strength of the deposited weld metal: 70,000 psi (~490 MPa)
S – Solid wire
6...
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...
