“…The purpose of this section is to obtain usable brazing joints. This paper does not intend to find the optimal welding process parameters, but focuses on the previous joint design [ 18 ]. In the experiment, scratch brazing was utilized to connect 1060 pure aluminum and H62 brass.…”

In order to avoid the adverse effects of additional moment and stress concentration of traditional lap joints, a new lap joint was put forward, according to the concept of “equal load-carrying”. Through static analysis and brazing characteristics consideration, the equal load-carrying design method of Al–Cu lap joint based on brazing method was established. Through three types of brazing, the relationship among two fracture modes, brazing process and static tension curve of lap joint, was analyzed. The results demonstrated that the selection of solder was required to simultaneously meet the requirements of brazability and mechanical properties. A certain relationship existed between the fracture mode of the lap joint and the static tensile curve, while the segments of the static tensile curve corresponded to the fracture paths of the two fracture modes. When the brazing holding time was quite short, the interface bonding was poor, while the bearing capacity of the joint was low; when the holding time was suitable, the bearing capacity of the joint reached the corresponding highest, while the fracture mode conformed to the equal load-carrying design; when the brazing holding time was quite long, the bearing capacity of the joint remained at a high level, but the fracture mode was the same as the holding time was quite short.

The objectives of this research is to investigate the tensile strength and structure of metallography of the metal connection between aluminum and brass by the brazing method. The type of joining is the but joint using an alusol filler. Specimens were made according to ASME IX standards. The ASTM E8 standard was used to tensile test. The macro and micro photos was carried out using ASTM E407-07. A joint with a shear area of 350 mm 2 was broken when pulled with a load of 4.410 kN. The highest stress, strain and Young modulus was 12.601 N/mm 2 , 0.11 and 1.183 kN/mm 2 respectively. The porous microstructure was seen in the weld area facing to the brass material. The chemical composition of the specimens consisted of C 21.53%, Al 2 O 3 37.20%, CuO 13.63%, and ZnO 27.64% from the EDX results.

“…Deep etching can be done by using a high concentration of acid solution to scrape the surface of the brazed area [4]. The occurrence of fundamental physical-chemical processes on the surface of the base material is a prerequisite for getting a correctly constructed soldered joint that meets the prescribed operating requirements [5]. It is crucial to first acquire the best wettability and spread-ability of the used solders in order to enable capillary phenomena and a tight filling of the soldering gap with liquid solder [6].…”

Since hard metals are among the materials that liquid brazing alloys scarcely adhere to, they should not be brazed without first removing the surface layer after sintering. The electrolytic etching method, which gives the surfaces of materials that are hardly wettable very good energetic qualities, is given specific attention. Deep etching is done by using a high concentration of acid solution to roughen the surface. Both dry and wet settings are suitable for etching. An etching fluid is used for etching in a wet environment. Typically, the plate or metal is submerged in an etching solution, where the substance is chemically broken down. While in dry etching, the plasma’s gas phase is where the etching takes place. Due to the presence of plasma in this situation, the etching process that takes place combines chemical and physical processes. Plasma etching is another name for dry etching. Deep etching is an etching process to obtain a rougher surface. Wet deep etching requires a longer immersion time and even several immersions are required. The purpose of this study was to determine the effect of etching treatment in the brazing process of Aluminium-Mild steel for its microstructure and mechanical properties. The specimens in this study used aluminium 6000 series, mild steel, Alusol ER4043, and etching fluid. Mild steel surfaces are deep etched before brazing. Specimen manufacturing standard refers to ASTM D1002. A micro photo test was conducted to compare the surface conditions of aluminium and mild steel with and without etching treatment. The deep etching process is carried out in three variations of time, namely 20, 30, and 40 minutes. The results showed that the tensile strength increased with deep etching treatment on the surface.
