Influence of Diffusion Welding Time on Homogenous Steel Joints
Original language description
The paper deals with assessment of influence of welding time on welding joint creation. Diffusion welding method in inert gas (Ar 4.8) at low pressure was used. Homogenous welding joints were created from steel E296 (according to EN ISO 10025-2). Homogeneous welds were done for easy assessment of influence of diffusion welding time and temperature on resulting welding interface, which was closely observed. Due to diffusion of carbon and manganese, on the joint interface were created complex iron and manganese carbides (FeMn)3C. It was found that the amount of created carbides depended on temperature and time. At temperature 1000 °C the biggest quantities of carbides were created, already at time 900 s the continuous carbidic strip was created with thickness 1-2 μm. This strip is very brittle and is detrimental to joint properties.
