Welding of stainless steel pipe argon arc welding stainless steel pipe: it is required to have deep penetration, no oxide inclusion, and the heat affected zone can be as small as possible. Argon arc welding maintained by tungsten inert gas has good compliance, high welding quality and good penetration function. Its commodities are widely used in chemical,Application field: launch the market plan of stainless steel pipe in the target market of new products,OluStainless steel chimney tube, such as stainless steel kitchen equipment.(II) The price of steel has been running at a low level. From June to June , the overall performance of the domestic steel market was depressed. With the substantial release of crude steel production capacity, the market supply and demand fell into an imbalance, and the steel price entered the downward channel, which has been weak for more than four months. As of June , , the steel price index fell to . points, lower than the first points. The prices of eight steel varieties mainly counted by the iron and steel industry association were higher than at the beginning of the year different degrees When using this method, it should be noted that the water-soluble paper should be double-layer and must be pasted well, otherwise it is easy to cause damage and fall off of the water-soluble paper, resulting in loss of argon protection of the inner weld and oxidation, resulting in cutting of the weld junction and re welding, which can not ensure the welding quality and seriously affect the construction period. Therefore, the water-soluble paper should be strictly checked and pasted before welding.Olu,This material without titanium and niobium has an inherent tendency of intergranular corrosion. Intergranular corrosion can be reduced by adding titanium and niobium and stabilizing treatment. It is a kind of high alloy steel that can corrode in air or chemical corrosive medium. Stainless steel has beautiful surface and good corrosion resistance. It does not have to undergo surface treatment such as color plating to play a role of rust freeAt present, stainless steel backing is divided into two processes: back argon filling and non argon filling. Back argon filling protection can be divided into solid wire + TIG process and solid wire + TIG + water-soluble paper process; The back non argon filling protection is also divided into flux cored wire backing welding and welding rod (flux coated wire) backing TIG welding.Stainless steel and alloy tool steel (C content is expressed in thousandths), such as thousandth of CrNi (i.e. .% C), stainless C & le; .%, such as CRNI ultra low carbon C & le; .%, such as crnimo.
