Pipe ea tšepe ea A333-6 ke tšepe e nang le mocheso o tlase.Mocheso o fokolang oa 70 ° C. Hangata e tloaelehileng kapa e tloaelehileng le e halefileng mofani oa thepa ea mmuso.
Likahare tsa khabone tsa tšepe tsa A333-6 li tlase, ka hona li thatafatsa tšekamelo le tšekamelo e batang ea ho petsoha li batla li le nyane.Material toughness le ductility ke molemo, ka kakaretso ho le thata ho hlahisa ho thatafala le mapetsong, molemo weldability, boikhethelo W707Ni electrode le El theolelo ea terata TGS 1N, sebelisa argon ITU welding.Ho etsa bonnete ba hore toughness e ntle ea manonyeletso a cheselitsoeng.
Preheat
Ha mocheso ambient o ka tlase ho 5 ° C e hlokehang weldment preheating.Preheat mocheso oa 100-150 oC: Preheat bophara ba li-welds ka lehlakoreng le leng la 100 mm;ho futhumatsa lelakabe la oxyacetylene (neutral flame) mocheso oa pene e lekanyang e lekanyang mocheso ho 50 ~ 100 mm ho tloha bohareng ba weld.Lintlha tsa tekanyo li ajoa ka mokhoa o ts'oanang, e le ho laola mocheso hantle.
