| Comparative Oxidation Data |
| ULTIMET® alloy is readily welded by gas tungsten arc (GTAW), gas metal arc (GMAW), shielded metal arc (SMAW) and submerged arc (SAW) welding techniques. ULTIMET alloy possesses excellent resistance to hot cracking. The oxyacetylene welding process is not recommended. Post-weld annealing is not necessary with ULTIMET alloy.
Base Metal Preparation
The joint surface and adjacent area should be thoroughly cleaned before welding. All grease, oil, crayon marks, sulfur
compounds and other
foreign matter should be removed.
Preheating is not required, and weld interpass temperatures should be kept below 93°C (200°F) when possible.
Filler Metal Selection
Matching composition filler metal is recommended for joining ULTIMET alloy. For gas tungsten arc, gas metal arc welding, and submerged arc ULTIMET filler wire is recommended. For shielded metal arc welding, ULTIMET covered electrodes are recommended. Detailed information for ULTIMET alloy is available in Haynes publications
H-2089 and H-2099. |
