It has long been recognized that problems exist when welding is attempted at low ambient temperature. This is reflected in the restrictive clauses inserted in many specifications and codes. However, the nature and causes of these difficulties have never been clearly defined. This report considers the welding of steel at low ambient temperature under three headings: (1) the effects of cold on men, materials and machinery; (2) the metallurgical factors involved; and (3) the code requirements. An effort has been made to present the findings of all authoritative sources, including the results of correspondence with experts in many countries. The results of these considerations are presented in the form of a synopsis at the end of the report. They indicate that, provided proper precautions are taken, there is no absolute lower limit to the ambient temperature at which welding can be performed.
