Abstract

English

Over time, marine building technology has experienced very significant developments and there are several variations of improvements that can be made to suit needs and conditions. A ship's propeller is a ship component that often experiences collisions with hard objects floating in the water which can cause the blades of the propeller to experience damage such as bending, cracking or breaking. In this case, the propeller should be repaired immediately so as not to disrupt the smooth operation of the ship. Repairing broken propeller blades can be done using a welding process. Welding is a technique of joining metals by melting part of the parent metal and filler metal with or without additional metal and producing continuous metal. Underwater Welding is a welding process that occurs in wet conditions, meaning that the electrode and object are in direct contact with air, while Gas Tungsten Arc Welding (GTAW) is an electric arc welding process that uses an untreated electrode that does not melt. This research was conducted to analyze the welding measurement results of Gas Tungsten Arc Welding (GTAW) and Underwater Welding on brass materials. To support the analysis process, testing activities are carried out including tensile tests (tensile test), hardness tests (hardness test) and macrographic observations on the results of welding materials.

Bahasa Indonesia

Seiring berjalannya waktu, teknologi bangunan laut mengalami perkembangan yang sangat signifikan dan terdapat beberapa variasi perbaikan yang dapat dilakukan disesusaikan dengan kebutuhan dan kondisi. Propeller kapal merupakan komponen kapal yang seringkali mengalami benturan dengan benda-benda keras yang mengapung diperairan yang dapat menyebabkan daun dari propeller mengalami kerusakan seperti bengkok, retak, maupun patah. Dalam hal ini, propeller sesegera mungkin diperbaiki agar tidak mengganggu kelancaran operasional kapal. perbaikan daun propeller yang mengalami patah dapat dilakukan dengan proses pengelasan. Pengelasan (welding) adalah teknik penyambungan logam dengan cara mencairkan sebagian logam induk dan logam pengisi dengan atau tanpa logam penambah dan menghasilkan logam kontinyu. Underwater Welding merupakan proses pengelasan berlangsung dalam keadaan basah dalam arti bahwa elektroda maupun benda berhubungan langsung dengan air sedangkan pengelasan Gas Tungsten Arc Welding (GTAW) adalah suatu proses pengelasan busur listrik yang menggunakan elektroda tak terumpan yang tidak ikut mencair. Penelitian ini dilakukan untuk menganalisa hasil perbandingan pengelasan Gas Tungsten Arc Welding (GTAW) dan Underwater Welding pada material berbahan kuningan. Untuk menunjang proses analisa tersebut, maka dilakukan kegiatan pengujian diantaranya uji tarik (tensile test), uji kekerasan (hardness test) dan pengamatan makrografi pada hasil pengelasan material
