Arc Welding Technology
Arc welding weld is a common processed type of welding wire. Here mainly introduce this welding detailed info.
Welding is a fabrication process used to join materials, usually metals or thermos plastics together. During welding, the pieces to be joined (the workpieces) are melted at the joining inter face and usually a filler materials added to form spool of molten material (the weld pool) that solid to become strong joint.
Arc Welding description:
A welding power supply is used to create and maintain an electric arc between an electrode and the base material to melt metals at the welding point. In such welding processes the power supply could be AC or DC, the electrode could be consume able or non-consume able and a filler material may or may not beaded.
The most common types of arc welding are:
Shielded Metal Arc Welding (SMAW): A process that uses a coated.
Consume able electrode to lay the weld.As the electrode melts, the (flux) coating disintegrates, giving off shielding gases that protect the weld area from at magnetospheric and provide molten slag which covers the filler metal as it travels from the electrode to the weld pool. Once part of the weld pool, the slag floats to the surface and protects the weld from contamination as it solidifies. Once hardened, the slag must be chipped away to reveal the finished weld.
