不銹鋼封頭優勢(shi)特點，不(bu)銹(xiu)鋼(gang)通常按(an)基(ji)體(ti)組織分為：鐵素(su)體(ti)不(bu)銹(xiu)鋼(gang)。沖(chong)(chong)壓彎頭的制(zhi)作(zuo)工(gong)藝(yi)首先焊(han)接一個(ge)橫(heng)截面(mian)為多(duo)邊形(xing)的多(duo)棱環(huan)殼(ke)或兩端封閉的多(duo)棱扇(shan)形(xing)殼(ke),內(nei)部沖(chong)(chong)滿壓力介質后,施以內(nei)壓,在(zai)內(nei)壓作(zuo)用(yong)下(xia)橫(heng)截面(mian)由多(duo)邊形(xing)逐漸變成(cheng)(cheng)圓(yuan),朂(xu)終成(cheng)(cheng)為一個(ge)圓(yuan)形(xing)環(huan)殼(ke).

沖壓封頭進行焊接：為防止因為加熱而產生睛間侵蝕,焊接電流不宜太大,比碳鋼焊條較少%左右,電弧不宜過長,層間快冷,以窄焊道為宜.沖壓封頭以連接管件為主,這一產品的發展領域能夠擔當重任,具備國際******技術水平而啟航.目標面向國際先進的建筑業及船舶業等相關行業.坯料為平板或可展曲面,因而下料簡單,精度容易保證,組裝焊接方便，沖壓所使用的模具稱為沖壓模具,簡稱沖模.因不需要任何專用設備,尤其適合于現場加工大型碳鋼封頭.)由于上述二條原因,可以縮短制造周期,生產成本大大降低.不需管坯作原料,可節約制管設備及模具費用,且可得到任意大直徑而壁厚相對較薄的碳鋼封頭。
