Pogoste potrebe po temperaturi sušenja varilnega materiala

Welded parts are an important part of the structure of various types of engineering machinery and equipment. Welded components must not only meet the product design performance and parameter requirements, but also require welded joints to have higher reliability. At the same time, the crack prevention and repair technology of welded parts is also required to be more stringent.
Enterprises have established an effective quality control system in the design, processing, and inspection of product structural parts, striving to improve the performance of welded joints, prevent and eliminate welding defects, and ensure the reliability of welds. However, welding is regarded as a "special process" due to its own characteristics. Preheating before welding, slow cooling after welding, controlling interlayer Temperatura in toplotna obdelava po varjenju sta učinkoviti metodi za preprečevanje hladnih razpok v jeklom z visoko trdnostjo s slabo variabilnostjo in neizogibnimi strukturnimi oblikami z visokimi omejitvami .
V postopku varjenja je sušenje varilnih materialov zelo pomemben korak . Na splošno je treba navadnih palic za varjenje iz ogljikovega jekla peči, vendar je treba palice iz litega železa peči, da se izboljša kakovost varjenja. lahko vzdržuje prvotno zmogljivost po sušenju, ne da bi to vplivalo na njegovo uporabo .
Pogoji sušenja varilnih palic različnih vrst premazov so naslednji (referenčne vrednosti):
Kisline varilne palice se pečejo na 150-200 za 1H
Alkalne varilne palice se pečejo na 350-400 za 1H
Varilne palice celuloze so pečene pri 80 stopinjah za 1.5-2 h
Grafitne varilne palice so pečene pri 200 stopinjah za 1 uro
