| Abstract: | In the paper,the argon concentrations are measured by argon gas analyzer during the weldings of high alloy steel,such as stainless steel,martensite steel and etc,of which the effect on weld internal quality is discussed.It is shown from the experiments that the argon concentration in the pipes has significant effect on root protection of weld,which is critical to welding quality. |
