Spin Arc Technologies – A Technological Breakthrough in MIG Process
Mr. Neeraj Lohia from Bug-O Systems International, India gave a talk on the subject on Apr 13, 2016. Initially, he discussed various flexible automation solutions available with them for different applications involving butt, fillet welding, etc. In the later part, he covered the details of Spin Arc Technologies. It is a unique development of Bug-O systems which gives a spin to the arc with a cam arrangement at the tip of the wire. This gives a stirring effect to the arc thereby giving advantages like improved penetration, wider gap bridging, refined microstructures improving the strength and toughness properties, etc. The other advantage is that it comes as a separate attachment and can be used with any type of power sources. WRI is planning to procure one to develop some innovative applications.

INTERNATIONAL SEMINARS

Seminar by JWRI

Following the signing of MOU between WRI and JWRI, a seminar by JWRI on the following topics were organised for the executives of WRI and BHEL.

Plasma diagnostics and simulation of welding arcs - Prof. Manabu Tanaka
The presentation threw light on the experimental work which explains the temperature distribution pattern in the GMAW arc and also the now-why of the observation, that the core of the arc shows a lower temperature, as compared to the outside of the arc and this is due to metal vapour in the arc plasma. The experimentation work involved measurement of plasma temperature at various zones of the arc and metal vapour concentration at these zones. Using a pure iron wire GMAW arc, and analysing using a specially developed set of monochromators for Ar and Fe with high speed photography, the above could be explained. The increasing iron metal vapour in the plasma increases radiation loss from the plasma, contributing to the relatively lower temperature at the centre of the arc. The presentations gave an insight into the potential of these tools to understand the basic arc phenomena in welding and also linking them with numerical modelling data. Measuring is believing!

Time resolved x ray diffraction analysis of phase transformation of steel weld - Prof. Hidenori Terasaki
The presentation by Prof. Terasaki explained the microstructural changes in the welding process by effective X-ray diffraction. Three potential tools for such studies were explained. The first example used the bright x-rays generated by the large Synchrotron Radiation Source facility at Hyogo, where a multi-axis goniometer with a TIG welding fixture with remote handling is used, around the x-ray source. The bright x-ray diffraction patterns versus the temperature are tracked, and this helps in identifying the various metallurgical phases as they transform. Another special facility available and a powerful tool at JWRI is Laser Scanning Confocal Microscopy (LSCM). Here, a sample is kept at the focal point of a Halogen lamp and a He-Ne Laser is used to scan the surface. As the material sample is heated and cooled inside the pure argon chamber using infra-red furnace, the high temperature LSCM tracks the microstructural changes point by point and a computer generates the 3D picture of the surface. Similarly, there is a provision to examine minor phases in weld metal using SEM with Electron Back Scatter Diffraction (SEM-EBSD).Seeing is believing!

Macro and micro plasticity analysis for fatigue life assessment of steel - Prof. Seiichiro Tsutsumi
The lecture by Prof. Tsutsumi explained the trends in Modelling studies in designing for fatigue as also life assessment.  The elasto – plastic constitutive modelling for low / high cycle fatigue behaviour and prediction of crack nucleation life on the macro scale and the Crystal Plasticity FE Analysis of cyclic softening behaviour under macroscopically elastic stresses, were explained in this context. The studies at JWRI have been able to get good correlation between the experimental and modelling studies. The modelling tool has wider potential in fracture mechanics studies. Modelling is believing!
