Abstract

The better welding results are always a scientific challenge in welding engineering. This is to ensure the connection functions properly according to its designation. The main purpose of this study was to determine the effect of electrode drying temperature on the mechanical properties of ASTM A36 steel weld joint. This research was conducted at the Condet Welding Training Center and PT. Gamma Hepsi Condet. The tests carried out were visual tests, radiographs, and tensile tests. The results showed that the drying of the electrode E 7018 without an oven had a lot of welding defects on the inside in the form of porosity about 2 mm. The results showed that the highest tensile strength of 50.01 kgf/mm² was found in specimens using an electrode drying temperature of 230ºC.

Abstract

A custom spray coating refill equipment has been designed and fabrication. For this reason, it is necessary to trial the equipment that has been made. This study aims to determine the performance of custom spray coating refill equipment. For a comparison parameter, coating and thinner mixture variations were conducted to determine the adhesion and thickness of the coating layer formed. The coating used in this experiment was Nitrocellulose (NC) and Polyurethane (PU) thinner. The ratio of coating and thinner mixture used are 1:1.5, 1:2, and 1:2.5. After mixing, the mixture was put into the sprayer using custom spray paint refill equipment. The mixture of coating and thinner was sprayed onto the SPCC steel plate. To measure, the adhesion and thickness of the coating layers, a cross-cut tool (according to ASTM-D3359) and a thickness gauge (according to the ASTM-AMT15) were carried out respectively. It seems the spray paint refill equipment was functioning properly. This is due to the quality of the coating layers having good adhesion, shown by all specimens getting 5B classification (0% not peeled off). Moreover, an increase in the thinner composition is lead to a decrease in the coating thickness.
