Abstract

Carbon steel is a type of alloy steel consisting of various elements, especially iron (Fe) and carbon (C). In general, the properties of steel are affected by the percentage of carbon and the microstructure of steel which is affected by steel composition and heat treatment. The welding process can change the structure and composition of steel. The safety of weld results can be carried out after welding using a heat treatment process. This tempering aims to obtain better and desired mechanical properties. Tempering is carried out using temperatures of 200⁰C, 250⁰C and 300⁰C with cooling using air media and mechanical testing will be carried out.The results of this research showed that tempering temperature had an effect on the hardness value of medium carbon steel resulting from FCAW welding. The hardness value at a temperature of 200℃ was 54.75, a temperature of 250℃ was 53.00 and a temperature of 300℃ was 52.04. The higher the temperature, the lower the hardness value and conversely, the lower the tempering temperature, the higher the hardness value.Keywords: Welding, Tempering, Hardness

Abstract

GMAW (Gas Metal Arc Welding), which is a solid or tubular welding electrode that is fed continuously mechanically from a roll of electrode wire inside the welding machine. The electrode is fed via a gun or torch by maintaining the height of the arc formed between the tip of the electrode wire and the material being welded or the base metal. GMAW (Gas Metal Arc Welding) is MAG (Metal Active Gas) and MIG (Metal Inert Gas) welding which is very efficient and fast in the process.Low carbon steel contains less than 0.3% carbon in the carbon steel mixture. Low carbon steel cannot be hardened because the carbon content is not enough to form a martensite structure. Welded joints are material or plate joints that are used for the welding process with the aim of getting maximum penetration from the joint.In this research, we are looking at the effect of the GMAW (Gas Metal Arc Welding) welding process with MIG (Metal Inert Gas) type on ST-42 steel by varying the V seam angle with a stick out height of 5 mm on the mechanical properties in the HAZ area.The hardness value before the welding process at an angle of 15 is in the HAZ area of 30.03 HRD for corners 30 and 45 is 32.51 HRD and 33.98 HRD, while for the impact strength at an angle of 15 is 0.2725 J/mm2, an angle of 30  and 45 namely 0.2439 J/mm2 and 0.2320 J/mm2 Keywords: Welding, HAZ (Heat Affected Zone), Impact Strength, Hardness

Abstract

Painting is a process of applying paint in liquid form to an object, to create a thin layer which then creates a hard layer or layer of paint. The function of painting itself is to give a layer to an object so that the object's lifespan can be longer. Attachment of paint to the surface can be done in many ways, wiping, smearing, brushing, spraying, dipping or in other ways. Attachment of paint by spraying is the paint attachment that is most often found in automotive painting workshops. Apart from that, attaching paint by spraying is easier in adjusting the area where painting will be carried out, the results are also good if done correctly. The quality of good painting results is influenced by many factors such as skills, materials used, etc., while determining good painting results is based on several factors, such as surface roughness, gloss power, etc. The hardness of the painting results is also greatly influenced by the percentage of hardener mixture in the paint mixture. The paint in question here is color paint (top coat). This research is to determine the best percentage of clearcoat in the painting process by testing the hardness of the painting results. The results obtained by varying the percentage of the mixture in the best clearcoat are in the percentage variations of 100 (Base): 55 (Hardener) + Thiner or Solvent (10% of Base) is 83.49 H, 100 (Base): 55 (Hardener) + Thiner or Solven (10% of Base) is 82.99 H, 100 (Base) : 45 (Hardener) + Thiner or Solven (10% from Base) is 82.51 H and the lowest is the variation 100 (Base): 60 (Hardener) + Thiner or Solvent (10% of Base) namely 79.57 H. Keywords: Painting, Clearcoat, Hardener and Paint hardness
