Study Application Of Welding Technique Of Oxygen Lance Nozzle

Welding technique is the result of the development of industry and science technology, and one of the important component part of modern manufacturing industry technology, The test work out a feasiblety welding technological scheme's by means of studying oxygen lance nozzle's technological difficulty, in order to guarantee use function order。First, take a syntheical investigate and study the development of welding technique at home and aborad, the tend of oxygen lance nozzle technique, and the demand to improve technology function of product from market。On the basis of above work, take a synthetical analyse on choice of welding method。According to the result, define the main study aim of the text。These are analyse the product copper-copper and copper-steel welding technological, define a suitable technology scheme, and come up to a fit quality to meet it's use function。Secondly , make a systematic study on product's copper-copper welding technology。Do main analyse on the welding function of copper and it's alloy; brazing function; evolved course of brazing joint includes the metal composition of filler metal, parent metal, and brazing technological on oxygen lance nozzle's inside structure, by brazing filler and study on nozzle's welding function, use copper-steed electron beam welded, tungsten plate argon are welded and melt plate argon are welded, etc。according to the study result , define a suitable technology scheme so as to botch process, As a result of product it's quality come up to all technical target。At last, carry on economy benefit count for the text study, test and verified the study application effect, and come to the study conclusion。In brief of the conclusion is the text study reach to goal of the work plan and has a fine extend prospect。...
