Preparation And Evaluation

An Al-5.4Si-0.5Mg filler wire was developed and produced by direct chill (DC) casting, extrusion, and roll-die and hole-die drawing for the welding of newly developed Mg-containing high-Si aluminum alloys. The Al-12.7Si-0.7Mg alloy plates were butt-welded by tungsten inert gas arc welding (TIG) method using the as-produced welding wire. The microstructures and mechanical properties of these welded joints in different solid solution and artificial aging treatment conditions were studied to evaluate the weld qualities of the novel welding wire. The results showed that the Al-5.4Si-0.5Mg welding wire was an ideal special welding wire of the Al-12.7Si-0.7Mg alloy and the filler metal proved to be heat-treatable. The welded joints exhibited much higher mechanical properties after the post-weld heat treatment (PWHT). All of this provides the possibility of wide application of the novel Al-5.4Si-0.5Mg welding wire and the Al-12.7Si-0.7Mg alloy weldments.

Semi-automatic and automatic pulsed gas metal arc welding (GMAW) of aluminium alloy 5083 with ER5356 filler wire causes considerable softening in the weld. The tensile strength of dressed automatic welds approaches that of the base metal, but the stress concentration caused by the weld toe in undressed semi-automatic welds reduced the tensile strength significantly. Fully automatic welds displayed improved fatigue properties compared to semi-automatic welds.

The Status

There is an increase towards reducing the weight of structures through the use of aluminium alloys in different industries like aerospace, automotive, etc. This growing interest would lead towards using dissimilar aluminium alloys which would require welding. TIG and friction stir welding are the well-known techniques that are currently suitable for joining dissimilar aluminium alloys. The welding of dissimilar alloys has its own dynamics which impact on the quality of the weld. This then suggests that there should be a process which can be used to improve the dissimilar alloys welds post their production. Friction stir processing is viewed as one of the techniques that could be used to improve the mechanical properties of the material. This paper reports on the status and the advancement of FSW, TIG and FSP technique. It further looks at the variation use of FSP on TIG and FSW welded joints with the purpose of identifying the knowledge gap.

Sering kali di industri suatu komponen atau struktur dari logam aluminium (aluminium alloys) harusmengalami proses manufaktur pengelasan (welding) sebagai salah satu metode penyambungan logam (metaljoining) dan perlakuan panas (heat treatment) untuk memperoleh atau mengubah sifat tertentu dari logamtersebut, karena itu perlu dilakukan analisis terhadap kombinasi kedua proses tersebut. Penelitian inibertujuan mengetahui pengaruh kombinasi pengelasan dan perlakuan panas terhadap sifat mekanik(mechanical properties) logam aluminium.Material teknik yang digunakan adalah logam aluminium 6061, proses pengelasan yang dilakukanadalah tungsten inert gas (TIG welding) atau GTAW (Gas Tungsten Arc Welding), proses perlakuan panasyang dilakukan adalah aging (precipitation hardening/ strengthening), pengujian yang dilaksanakan adalahpengujian tarik (tensile/tension test) dan pengujian kekerasan (hardness test).Kekuatan logam rata-rata setelah dilakukan proses pengelasan adalah 28,5 Kgf/mm2 artinya logamini mampu menahan beban hingga sebesar itu tanpa mengalami perpatahan (fracture), sedangkan kekuatanlogam lasan setelah dilakukan proses perlakuan panas rata-rata meningkat menjadi 48,7 Kgf/mm2. Secaraumum nilai kekerasan logam berbanding lurus dengan kekuatannya sehingga kekerasan logam lasan setelahdilakukan proses perlakuan panas juga meningkat. Kesimpulan yang diperoleh dari penelitian ini adalahbahwa proses perlakuan panas artificial aging pada hasil proses pengelasan logam aluminium secara umumakan meningkatkan sifat mekanik.

The paper studies structure and mechanical properties of welded joints of hot-pressed panels and profiles manufactured by JSC Arkonik SMZ from aluminum-magnesium 1565ch alloy at the temperature range of –165 to 150°C. It is established that the nature of changes in the properties of welded joints of pressed panels and profiles of 1565ch alloy made by manual argon-arc welding with non-consumable electrodes of ArDS with filler material SwAMg-61 at various test temperatures is similar to changes of welded joints of rolled sheets. When the test temperature is lowered, low-temperature hardening of the welded joints takes place – at a cryogenic temperature (–165°C), 20–30% of strength is gained comparing to 20°C. The prolonged aging of welded joints at an elevated temperature (150°C) leads to strength decrease by 25–30% compared to that of 20°C. The coefficient of strength of welded joints with reinforced joint is not less than 0.9 of the actual strength of the base metal at all test temperatures.
