What is Welding? Did You Know? Welding has been called, "the best kept secret" in career planning. Welding is widely use in construction, manufacturing, and many other industries, making it a critical skill that will always be in demand. From the beginning of civilization, we have relied on the skills of welders to enrich our life.
Vēsture of Metināšana
Attēlojumi of senie metinātāji un darbarīki ir atrasts iekšā ilgi aizzīmogots Ēģipte kapenes. Prezidents Rūzvelts, in a burts to Prime Minister Winston Churchill, lielīties par the discovery of a new welding technique enableling America to build ships with a speed unequaled in the history of shipbuilding. See how discoveries and developments in welding processes and metalurgy led to the the technological marvels that changed the world we live in today.
Kas Is Metināšana, Anyway?
• Metināšana is savienojums of divi vai vairāk materiāli caur karstums vai siltums un spiediens, formēšana a saite starp divi gabali of metāls.
• Tērauds kausē at 2,800 grādi Fārenheits.
• A populārs forma of metināšana, gāze metāls loks metināšana (GMAW), uses a patērējams stieple elektrods. GMAW is common in high-production manufacturing and construction. Welding a frame for a chopper would require this MIG welding.
• Gas Tungsten Arc Welding (GTAW) uses a non-consumable tungsten electrode to make highprecision welds. GTAW is common in the aerospace, nuclear, and food industries. It is also called TIG welding, (melting together high alloy thin materials, such as stainless steel and titanium) puts little heat into the material causing less distortion.
• Ekranēts Metāls Loks Metināšana (SMAW) izmanto ar plūsmu pārklāti elektrodi. Bieži sauc "stick" or "stick-electrode" metināšana, SMAW is a frequent choice for repair and occasional welding.
• Still another welding method, Resistance Welding, uses electric resistance and pressure to fuse metals, instead of an arc.
