First, the authors describe the objects of these researches, materials and welding scheme which are most practically used for plate work of mild steel. Next, they describe the apparatus and procedures for determining the various properties of butt welded joint at elevated and lowered temperatures ranging from 100 to 600℃ and from 0° to -40℃ respectively. In the third section, the factors which may influence on the resulting tensile and impact resistances of butt welded test pieces are considered, and lastly the thermal effects on the physical properties of the adjacent steel plate are discussed. So far as the ultimate strength is concerned, a strong weld at a low temperature is generally a strong weld at a high temperature as well. The current investigation of welds at lower temperature was made possible through the co-operation of the outhors.
