WELDINGULTIMET alloy is readilywelded by gas tungsten arc(GTAW), gas metal arc(GMAW), shielded metalarc (SMAW) and submergedarc (SAW) weldingtechniques. ULTIMET alloypossesses excellentresistance to hot cracking.The oxyacetylene weldingprocess is not recommended.Post-weld annealingis not necessary withULTIMET alloy.Base Metal PreparationThe joint surface andadjacent area should bethoroughly cleaned beforewelding. All grease, oil,crayon marks, sulfurcompounds and otherforeign matter should beremoved.Preheating is not required,and weld interpass temperaturesshould be keptbelow 93°C (200°F) whenpossible.Filler Metal SelectionMatching composition fillermetal is recommended forjoining ULTIMET alloy. Forgas tungsten arc, gas metalarc welding, and submergedarc ULTIMET fillerwire is recommended. Forshielded metal arc welding,ULTIMET covered electrodesare recommended.Detailed information forULTIMET alloy is availablein Haynes publicationsH-2089 and H-2099.ULTIMET alloy was selected for this greenpigment mixer bowl and blade to provideenhanced corrosion and wear resistantce. Themixer bowl has been lined with ULTIMET sheetand the blade was weld overlayed withULTIMET wire.Typical Transverse Tensile Data, WeldmentsTest Ultimate Yield Strength Elongation inWeld Temperature Tensile Strength, at 0.2% Offset, 2 in.
