Materials & Welding

Is it an option to only use a spot GTAW weld for fixture of the thread Or seal it with Loctite To prevent shrinkage during welding, very low heat input process like laser welding can be an option Regards, Weld-Tech BV Jurgen Prinsen (MSc/IWE) Van: "Balasubramanian M" <bala.smi@gmail.com> Aan: "materials-welding" <materials-welding@googlegroups.com> Cc: "Balasubramanian M" <bala.smi@gmail.com> Verzonden: Donderdag 31 augustus 2023 09:36:43 Onderwerp: [MW:34520] I request for your expert advice Dear Experts, I am writing this for you to give me some advice/suggestions. We are facing a severe issue in welding the Body-end connector joint in our small-size (0.75" 800#) 2-piece Ball Valves Lever Operated SW ends (MOC 316 with PTFE seat ring). Since our client wants us to seal weld the Body-End connector joint, after assembly and final testing prior to despatch. We find that after welding, in TIG, the valve becomes very difficult to operat...

  Aluminium Alloy 6082 has very good weldability, but strength is lowered in the weld zone. When welded to itself, alloy 4043 wire is  recommended. If welding Aluminium alloy 6082 to 7005, alloy 5356 is used.  You have not mentioned the parameters selected ,  tests conducted after welding, or approval standards   followed (AWS D 1.2 /  ISO 15614-2 etc. ). Whether NDT (Radiography and visual) or DT (mechanical tests) were carried out before distortion correction . Pores may create under-bead c racks and potential causes include: Presence of molecular hydrogen. hard microstructure. High weld residual stresses. Fast cooling rate. Not applying preheat or insufficient preheating for welding.        ·     Welding without cleaning moisture , etc.             During the welding of the Aluminium alloy, hydrogen can cause pores, because  its solubility  in liquid Aluminium is much higher than  that in solid Aluminium.

generally 70S2 is not being used in GMAW eventhough it calls for both process, Any reasons?
