We are putting a few changes in place to prevent further cracking including changing the filler rod for future parts. Also, we can afford to reduce the mechanical properties away from the weldments slightly (I appreciate the alloy ... WebThese aluminum alloys can be difficult to arc weld without encountering problems during and/or after welding. These problems are usually associated with cracking, most often, hot cracking and on occasion, …
WebMeta-Lax Weld Conditioning will relieve the heat stresses as they are being introduced during weld solidification. This procedure produces several desirable benefits for the weld metal and the heat affected zone including eliminating the need for post-weld stress relief. WebStress Relieving Furnace It is worth noting that many heat treatments and welding processes cause stresses in the material that can lead to warpage either after the heat treating process or during subsequent machining operations. Of specific concern is the stress induced by welding.
WebHeat treatments include stress relieving, austenitizing, normalizing, annealing, quenching, and tempering (Ref 1). Heat treating may also involve chemical or additional physical processes.
