In order to simplify the robot preparation before welding and improve automation of whole process, an intelligent expert system for Gas Metal Arc Welding is designed in this paper. system, user inputs initial information output interface displays suitable procedure parameter schemes. The can choose schemes according actual requirements or directly generate specification required by enterprise f...

In this research, the effect of vibration at the resonant range (75 Hz) on the hardness and tensile strength of AA-5083-H321 aluminum alloy, were welded by gas metal arc welding (GMAW) investigated. Vibration forces were ranged from 850 N to 2200 N, under identical welding parameters. Tensile strength and hardness testing of welded samples were performed. After mechanical tests, the fracture su...

On-l ine quality control in automated welding operations is an important factor contributing to higher productivity, lower costs and greater reliability of the welded components. However, the development of on-l ine inspection techniques and feedback control is still in its infancy. Sound signature produced by GMAW contains information about the behavior of the arc column, the molten metal and ...

Gas metal arc welding (GMAW) is a process in which an electric formed between wire electrode and workpiece alongside shielding gas to protect the from contaminants. There are several ways molten droplet can be transferred weld pool known as transfer modes. Identifying mode automatically essential monitor control process, especially automated processes employed modern Industry 4.0 manufacturing ...

Today, welding tasks can be accomplished in two ways: 1) Manual or conventional, which is made by humans with a welding gun; and 2) Automated welding that is carried out by robots, this robots are called “Welding Robots”. Current welding robots are able to perform welding tasks continuously under different working conditions in low-scale production such as shipbuilding or in high-scale producti...

The conjoint influence of welding and artificial aging on mechanical properties were investigated for extrusions of aluminum alloy 6063, 6061, and 6005A. Uniaxial tensile tests were conducted on the aluminum alloys 6063-T4, 6061-T4, and 6005A-T1 in both the as-received (AR) and as-welded (AW) conditions. Tensile tests were also conducted on the AR and AW alloys, subsequent to artificial aging. ...

In industries and research organizations most widely used welding methods are shield metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW) and submerged arc welding (SAW). The SAW process is often preferred because it offers high production rate, high melting efficiency, ease of automation and low operator skill requirement. This review will be very helpful for...
