Almost 20 Republican Party candidates ran for the office, including two previous nominees for governor in 19, as well as 15 Democrats and some non-affiliates/third-party members. The Oregonian anticipated the election to have "the first competitive Democratic primary in more than a decade and potentially the closest such race since 2002." Willamette Week anticipated a "wide open field of Democrats", citing the lack of an incumbent. Due to term limits, she was ineligible for re-election in 2022. She was subsequently elected in the gubernatorial special election in 2016, and was re-elected to a full term in 2018. The incumbent governor, Democrat Kate Brown, took office on February 18, 2015, upon the resignation of John Kitzhaber. The 2022 Oregon gubernatorial election took place on November 8, 2022, to elect the governor of Oregon. In the fusion zone of the material, as expected there was decrease of hardness because of incidents which occurred during heating and cooling cycles.Democratic 2004 2008 2016 2020 Republican 2008 2012 2016 2020 Different hardness values were obtained on the parent material because of extrusion. Also, SEM analysis rendered possible to determine dendritic structures, inclusions which we couldn't have determined without SEM, and there was a chance to examine hardness of a metal part which had been produced by mechanical extrusion method. Not to pay attention to surface cleaning caused dendritic structures which were located as small clusters on the surface due to the NaCl droplets which were identified by EDX chemical composition analysis. As the results of the tests, first of all, it was shown that MIG is trickier method than TIG throughout implementation of welding. Different welding techniques have been used on this case and the sample has been examined by optical microscope, SEM, EDX and hardness test. No attention on purpose paid to surface cleaning. Because when it’s preferred instead of TIG, one of the major issues with MIG process for aluminum is implementation part( Handicraft requirements etc). MIG, the welding process which can be applied for many kind of materials, was used on 6XXX series of aluminum to perform a joining to be able to investigate hardships and trials of MIG welding on aluminum type of metal when it’s used instead of TIG process for nonspecific applications. Because of the diversity in available equipment and the wide variety of problems encountered, the following text presents for the guidance of the metallographer only those practices which experience has shown are generally satisfactory it cannot and does not describe the variations in technique required to solve individual specimen preparation problems. In special cases, the objective of the examination may require the development of less detail than in other cases but, under nearly all conditions, the proper selection and preparation of the specimen is of major importance. Scope 1.1 The primary objective of metallographic examinations is to reveal the constituents and structure of metals and their alloys by means of the a light optical or scanning electron microscope.
