Abstract

Heat straightening is a method of repairing material distortion caused by welding heat. Heat straightening is done by heating the material in an area that is distorted and cooled slowly in the air until the desired material dimensions tolerance appropriate are achieved. The Heat Straightening method is carried out at a range suhu 370℃-550℃ using the oxy-acetylene method for the heating process. This research is aimed to find out effect Heat Straightening proses the hardness value on ABS EH36 material. The hardness testing method used is the Hardness Vickers test with load applied 10kgf on Carbon Steel ABS EH 36. From the research it is known that the hardness value in the base metal area is higher than the heat straightening area with an average hardness value of 192.1 HV10 in the base metal area and an average hardness value of 185 HV10 in the heat straightening area.

Abstract

Pelapisan (cladding) material corrosion resistant alloy (CRA) menggunakan Inconel 625 memadukan properti ketahanan korosi Inconel 625 dan kekuatan (high strength) pipa baja API 5L X65. Sampel lapisan CRA difabrikasi dengan pengelasan Pulsed Gas Tungsten Arc Welding (GTAW). Filler metal ERNiCrMo-3 dengan dua merk yang berbeda, yaitu RW625 dan NM625, digunakan sebagai material CRA. Pengujian non-destruktif berupa visual testing, liquid penetrant testing dan ultrasonic testing menunjukkan tidak terdapat cacat pengelasan pada deposisi lapisan CRA maupun antar-muka lapisan CRA dan base metal. Pengujian kekerasan Vickers menunjukkan NM625 memiliki nilai kekerasan 228 ±8,8 HV10 (layer 1) dan 231.6 ±10,8 HV10 (layer 2), sedangkan RW625 memiliki nilai kekerasan 203.4 ±8,1 HV10 (layer 1) dan 213.6 ±6,3 HV10. Kedua filler metal menghasilkan nilai Pitting Resistance Equivalent Number (PREN) yang sama 48, yang menunjukkan kedua filler metal memiliki properti ketahanan korosi yang sama.
