Study and Characterization of EN AW 6181/6082-T6 and EN AC
metals Article Study and Characterization of EN AW 6181/6082-T6 and EN AC 42100-T6 Aluminum Alloy Welding of Structural Applications: Metal Inert Gas (MIG), Cold Metal Transfer (CMT), and Fiber Laser-MIG Hybrid Comparison Giovanna Cornacchia * and Silvia Cecchel DIMI, Department of Industrial and Mechanical Engineering, University of Brescia, via Branze 38, 25123 Brescia, Italy; [email protected] * Correspondence: [email protected]; Tel.: +39-030-371-5827; Fax: +39-030-370-2448 Received: 18 February 2020; Accepted: 26 March 2020; Published: 27 March 2020 Abstract: The present research investigates the effects of different welding techniques, namely traditional metal inert gas (MIG), cold metal transfer (CMT), and fiber laser-MIG hybrid, on the microstructural and mechanical properties of joints between extruded EN AW 6181/6082-T6 and cast EN AC 42100-T6 aluminum alloys. These types of weld are very interesting for junctions of Al-alloys parts in the transportation field to promote the lightweight of a large scale chassis. The weld joints were characterized through various metallurgical methods including optical microscopy and hardness measurements to assess their microstructure and to individuate the nature of the intermetallics, their morphology, and distribution. The results allowed for the evaluation of the discrepancies between the welding technologies (MIG, CMT, fiber laser) on different aluminum alloys that represent an exhaustive range of possible joints of a frame. For this reason, both simple bar samples and real junctions of a prototype frame of a sports car were studied and, compared where possible. The study demonstrated the higher quality of innovative CMT and fiber laser-MIG hybrid welding than traditional MIG and the comparison between casting and extrusion techniques provide some inputs for future developments in the automotive field. -

Department of The University of British Columbia 2075 Wesbrook Place Vancouver, Canada V6T 1W5 Date 7 ABSTRACT Previous studies of the properties of electroslag weld metal have been done using electroslag remelted ingots made under welding conditions. This procedure assumes the electrical and thermal regimes of these pro• cesses to be equivalent. To test this assumption an experimental program was devised in which the remelted metal of an ingot and weld made with each of three slag systems was analysed and the mechanical properties examined. The results show that each process imparted different properties to the remelted metal by alloy and inclusion modification. Consequently the above assumption was proved invalid. Special consideration was given to the effect of inclusion composition and overall distribution toward mechanical properties. -

Construction of Metal Transfer Modes Maps for an ER4130 Filler Metal in GMAW Process
Construction of metal transfer modes maps for an ER4130 filler • metal in GMAW process Juan Camilo García-Viana, John Edison Morales, Emanuel Valencia & Jorge Enrique Giraldo-Barrada Universidad Nacional de Colombia, sede Medellín, Facultad de Minas, Medellín, Colombia. [email protected], [email protected], [email protected], [email protected] Received: April 30th, 2020. Received in revised form: August 21th, 2020. Accepted: September 15th, 2020 Abstract Metal transfer modes (MTMs) maps were constructed for GMAW process using ER4130 and 98%Ar-2%O2 shielding gas. There is no available MTMs maps for this filler metal which is used to obtain matching strength in welds of AISI 4130/4140 steels. These maps serve as tools to establish the MTM given a welding current and voltage, which is useful when an engineer is trying to qualify welding procedures according to construction codes. The maps were built analyzing current and voltage signals recorded at 5000 samples/second during bead- on-plate welds. The main advantage of this methodology is its simplicity of instrumentation without expensive cameras, but has low resolution and it is difficult to identify finer characteristics of MTMs, such as subgroups (repelled globular, streaming, rotational spray), drop diameter, explosive transfer, etc. Several MTMs were identified in the signal analysis and grouped into natural MTMs (short circuit, globular and spray) and interchangeable modes (short-circuit-globular, globular-spray and short-circuit-globular-spray). Palabras clave: metal transfer mode (MTM); MTM map; amperage signal; voltage signal; stubbing.

This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the workpieces to form a bond between them, without melting the workpieces. Many different energy sources can be used for welding, including a gas flame, an electric arc, a laser, an electron beam, friction, and ultrasound. While often an industrial process, welding can be done in many different environments, including open air, under water and in outer space. Regardless of location, welding remains dangerous, and precautions are taken to avoid burns, electric shock, eye damage, poisonous fumes, and overexposure to ultraviolet light.
