Numerical Modeling of Heat Affected Zone Cracking Tendency during Laser and Hybrid Laser-Arc Welding Processes
A two-dimensional thermal elasto-plastic numerical model is developed by finite element method to analyze and compare the mechanical driving factor for heat affected zone (HAZ) liquation cracking during laser welding and hybrid laser-arc welding techniques. Calculations of transient temperatures and cooling rates are used in conjunction with solidification theory to analyze weld pool characteri...
متن کاملHeat Affected Zone in Surfacing Chromium Ledeburitic Steel
Repair welding is not used enough in the industry 1 . One of the reasons for this lies in the insufficient and unrealiable knowledge in many segments of this area. A very important part is having appropriate knowledge of metallurgical processes in heating of the base material 2-4 . Unsuitable heating deteriorates the microstructure as it reduces toughness and fracture behaviour of the weld 5 . ...
متن کاملNumerical Simulation Of Heat Affected Zone Microstructure During Laser Surface Melting
Microstructural changes during laser welding and laser surface treatment has been regarded by many researchers. Most researches have focused on studying the effect of various process parameters on the size and microstructure of the heat affected zone. But some studies show that the initial microstructure of the base metal can also affect the heat affected zone dimensions and final microstructur...
متن کاملExtending the potential of evaporative cooling for heat-stress relief.
Factors were analyzed that limit the range of environmental conditions in which stress from heat may be relieved by evaporative cooling in shaded animals. Evaporative cooling reduces air temperature (Ta), but increases humidity. Equations were developed to predict Ta reduction as a function of ambient temperature and humidity and of humidity in cooled air. Predictions indicated that a reduction...
متن کاملExploring Heat Stress Relief Measures among the Australian Labour Force
Australia experiences frequent heat waves and generally high average temperatures throughout the continent with substantial impacts on human health and the economy. People adapt to heat by adopting various relief measures in their daily lives including changing their behaviour. Many labour intensive outdoor industries implement standards for heat stress management for their workforce. However, ...
