Welding of high-temperature alloys Cr20Ni32


Thermal cracks. 3 welding process (t) of groove shown below. Filler metal is nickel-units for Mou also, r Island (f Huxi Hai Liu New ● - A --- _ - one gold, so the bevel angle should be larger to help weld fusion. Back weld bead using double-sided surface forming the back with a grinding wheel. 70. groove Reliance store (2) welding process parameters are as follows: ① Press the temperature control layer below 60 ℃; @ removed with heat input, ie welding current 80 ~ 85A, the arc Voltage 21 ~ 23V, welding speed l8 ~ 21cm/min; @ _ welding process to ensure that the domain was clean mouth and welding, welding on both sides before the removal of the oil groove and the surface oxide, each layer of stainless steel weld metal are News wire brushes floor cleaning, polishing wheel on the topical treatment; ④ convex narrow weld formation, that is the beginning of the second floor. each layer to form a narrow bead convex. welding process, arc welding did not swing at the closing time electrode filled with back-arc pull-pit, to prevent the occurrence of crater cracks; ⑤ process route is as follows: clean groove side welding of a first forming a layer of positive news dealing with a question dealing with a solder layer of 100% polished color rear between the back layer of a weld inspection process a l ∞% 100% ray detection and color detection. 4 Process Assessment developed under the GB150 ~ 89 Wang Yi received bomb, according to JB4765-92 should be the technical requirements for process and product evaluation. welding process parameters : welding current 8lDA electric 'arc voltage 2l ~ 23v,[link widoczny dla zalogowanych], welding speed 15 ~ 18cm/min, layers News temperature 5O ℃. 2】 weld lamination layer, the slope at the form of supra Bin. nondestructive inspection splash: ray detection of 100%.
