不銹鋼封頭優勢特(te)點，不銹(xiu)鋼(gang)通常按基體(ti)組織分為(wei)：鐵素體(ti)不銹(xiu)鋼(gang)。沖(chong)壓彎(wan)頭的制作(zuo)工藝首先焊接一個(ge)橫(heng)(heng)截面為(wei)多邊(bian)形(xing)(xing)的多棱(leng)環殼(ke)或兩端(duan)封閉的多棱(leng)扇形(xing)(xing)殼(ke),內(nei)部(bu)沖(chong)滿壓力介質后,施以內(nei)壓,在(zai)內(nei)壓作(zuo)用下(xia)橫(heng)(heng)截面由多邊(bian)形(xing)(xing)逐漸變成圓(yuan),朂(xu)終成為(wei)一個(ge)圓(yuan)形(xing)(xing)環殼(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。
