Shielded hlau Arc vuam
Mar 13, 2016

Shielded hlau arc vuam (SMAW), los yog kev tuav hlau arc vuam (MMA los yog MMAW), flux shielded arc weldingor ncab thaum lo vuam, yog kev tuav arc welding uas siv ib tug consumable electrode them rau ib flux pw lub weld rau.

Ib chaw fais, nyob hauv daim ntawv alternating tam sim no los yog tam sim no mus ncaj ntawm ib welding zog mov, yog siv los tsim ib qho electric arc ntawm cov electrode thiab cov co los ua keeb. Cov workpiece thiab cov electrode melts txoj kev ua tus pas weld uas cools tsim ua se ua ke. Raws li tus weld nteg, flux txheej ntawm lub electrode disintegrates, muab rho tawm hauj lwm vapors uas yog ib shielding gas thiab muab slag, ib txheej bacteria uas ob qho tiv thaiv lub weld loj hauv paug atmospheric.

Vim yog lub versatility ntawm tus txheej txheem thiab cov simplicity nws cov khoom thiab cov lag luam, vuam hlau arc shielded yog ib lub ntiaj teb thawj thiab vuam dab nrov tshaj plaws. Nws dominates lwm welding muaj dab nyob hauv tus tu thiab kho kom kev lag luam, thiab txawm flux-cored arc vuam loj hlob nyob rau hauv tej chaw, SMAW tseem siv feem li txoj siv uas hnyav steel lug thiab muaj fabrication. Tus txheej txheem yuav siv feem ntau weld hlau thiab steels (xws li hlau stainless), tiam sis aluminium, npib tsib xee thiab tooj liab alloys yeej tseem yuav welded rau hom no.
