Abstract of Research Project:
Cost reduction is one of the most important challenges for the Swedish (global) industries. Welding costs has a great influence of the total product cost in Construction Equipment Products i.e. Wheel Loaders, Dum Trucks, Excavators etc. With the robot welding process Tandem Arc Welding technology a very productive welding process is available on the market. It is characterised by the arrangement of two wires in a special gas nozzle. On account of this a considerable increase of welding speed (m/min) by simultaneous increase of deposition rate (Kg/h) is achieved. This work will give a technical and economical survey over the process development made to present state of Tandem Arc welding process used at the Core Plant of Volvo Wheel Loaders AB, The Arvika Plant. The Tandem Arc welding process uses two power sources and two electrically separate contact tubes in a special gas nozzle. Because of that at both wire electrodes an independent adjustment of welding parameters is possible. n the first part of the project the attention will be paid to replace one of the solid wire (the tail wire) by metal cored wire (MCAW), and the second part of the project the parent material will be changed from"C-Mn steel" (300 MPa) to "High Strength Steel" (600 - 700 MPa). With these changes the welding speed will be increased from 0.8 m/min to 1.2 m/min and the welding cost will be reduced approximately 30%. Moreover, essential changing to the present process, new research results and industrial applications will be presented connected to welding quality, according to The Volvo Corporate Standard 5605,51, welding classes (1S0 5817) and the weld defect "cold lap" will be studied in co-operative projects. |

Abstract of Master Thesis:
This work demonstrates relations in MIG/MAG synergy data between different wire diameters. The work was carried out at the Royal Institute of Technology department of Welding Technology and the ESAB Welding Equipment AB Laxå Sweden. The important work of the thesis was to define the effects of wire diameters on the synergic relations in MIG/MAG welding in order to reduce the amount of work carried out by the welder. The previous experimental synergic data was analysed successfully by using two different approaches i.e. "Least Square Method" and "Exponential Function Method". Through this thesis work, it was noted that slope of the synergic relations increases with increasing wire diameter, while intercept of the synergic relations decreases with increasing wire diameter in most cases. Wrong synergic relations can be identify only by using the "Least Square Method" of the above mentioned two methods. It was also found that in the "Exponential Function Method", different materials have different value of exponential constant. It was also noted that between two methods, the "Least Square Method" was more reliable. |
