SAW is the process of undergoing welding arc obscure. In this mode, the welding arc burns obscured welder and is not exposed to radiation. Even heat recovery is more favorable – due to radiation losses are small.
\nIn submerged arc welding supplies drive mechanism bare electrode in the form of endless wire welding in place. Electric arc burns obscured submerged arc that gradually strew in a safe rob.Pra\u0161ek is partially dissolved in the slag, which covers and protects the weld formed threads. The filler material is bare electrode, which must be adjusted in composition to the base material and powder.
\nThe EPP welding gives at a glance a nice weld, and later when he analyzes we see that the fine-grained structure, because of the slow cooling of the weld and well protected from the surrounding influences. Melting u\u010dunek while welding is high.<\/p>\n
Characteristics of the process:
\n\u2022 Maximum productivity
\n\u2022 Very good protection weld
\n\u2022 automated welding takes place
\n\u2022 an extremely clean, even and smooth weld
\n\u2022 one varkom be made very large weld
\n\u2022 it is very suitable for surfacing of worn surfaces<\/p>\n
Usefulness of the procedure:
\n\u2022 to produce thick and flat welds
\n\u2022 tanks and tank under high pressure
\n\u2022 thick-walled tubes with a larger diameter
\n\u2022 renovation of cylinders and various impellers<\/p>\nngg_shortcode_0_placeholder\n
