Description
Предлагаетс способ упрочнени соедине ;11Я, сваренного стыковой электроконтактной сваркой с повторным нагревол после сварки.A method is proposed for hardening a joint; 11I welded by butt electric contact welding with repeated heating after welding.
Известные способы электрокоитактной ссарки деталей ас обеснечнвают сварным соединени м механнческой прочности, разной прочности ocFiOBiioro металла.Known methods of electro-contact locking of parts of ac impure weld metal joints with mechanical strength and different metal ocFiOBiioro strengths.
При сварке особен ю резко понижаютс предел усталости, ударна в зкость li преде; прочности сварного шва.When welding, the fatigue limit is sharply reduced, the impact strength li is exceeded; strength of the weld.
Предлагаемый способ существенно повышает прочность п предел усталости сварного соединени благодар то.му, что соединение нагревают до 900-1100° п при этой температуре сварной стык онрессовывают с применением давлени 1,5-2 кг/лш1The proposed method significantly increases the strength n. The fatigue limit of the welded joint due to the fact that the joint is heated to 900-1100 ° n at this temperature, the welded joint is pressed using a pressure of 1.5-2 kg / lsh1.
После этого сварное соединение, в зависимости от требований дальнейше; эксплуатации, может быть подвергнуто термической илн ме.ханнческой обработке.After that, the welded joint, depending on the requirements further; operation, may be subjected to thermal or mechanical processing.
Термомехаиический способ упрочнени сварного электроконтактного стыка может производитьс как непосредственно в зажимах контактно-сварочных машин, так и вне машины, на которой производилась сварка.The thermomechanical method of hardening a welded electric contact joint can be carried out both directly in the terminals of resistance welding machines and outside the machine where the welding was performed.
Кроме повышени прочности, нагрев с вторичным опрессованием унлотн ет сварной шов, ликвидиру при этом пеплотность околошовной зоны, неизбежную при сварке обычным электроконтактным методом , устран тем самым возможность развити микротрешин в услови х в эксплуатации.In addition to increasing strength, heating with secondary crimping of the weld seam, while eliminating the heat density of the heat-affected zone, which is unavoidable during welding by the usual electrocontact method, thereby eliminating the possibility of microcrack development under operating conditions.
