?b>贵州钢结?/b>它具备高溫、髙压、具备优良的密闭性的优势,今日大家就来实际了解一下焊接加工工艺,很感兴趣的盆友能? 看一?下列是贵州钢结构厂家收集相关资料小结的:</span> </p> <p> <span style="font-family:SimSun;font-size:16px;">1、挑选达标的焊接加工工艺,焊条直徑,焊接电流量,焊接速率,焊接电弧长短等,根据焊接加工工艺实验认证?/span> </p> <p> <span style="font-family:SimSun;font-size:16px;">2、清除焊?焊接前查验焊缝、拼装空隙是不是符合规定,精准定位焊是不是坚固,焊缝周边不可有油渍、锈物?/span> </p> <p> <span style="font-family:SimSun;font-size:16px;">3、蛋糕烘焙焊条应符合要求的溫度与時间,从烘干箱中取下的焊条,放到焊条保温桶内,随时使用随用?/span> </p> <p> <span style="font-family:SimSun;font-size:16px;">4、焊接电流量:依据焊件薄厚、焊接层级、焊条型号规格、直徑、电焊工掌握情况等要素,挑选适合的焊接电流量?/span> </p> <p> <span style="font-family:SimSun;font-size:16px;"><img src="/uploads/image/20201229/20201229162418_4524.jpg" alt="" /><br /> </span> </p> <p> <span style="font-family:SimSun;font-size:16px;">5、引?钢架结构角焊缝起降弧点应在焊缝顶端,宜超?1mm,不可随意打弧,点火引弧后应该马上将焊条从焊缝区打开,使焊条与预制构件间维持2~4mm空隙造成电弧?/span> </p> <p> <span style="font-family:SimSun;font-size:16px;">6、焊接速率:规定匀速焊接,确保焊缝薄厚、总宽匀称一致,从呼吸面罩内看溶池中钢水与炉渣维持等间距(2~2mm)为宜?/span> </p> <p> <span style="font-family:SimSun;font-size:16px;">7、焊接电弧长?依据焊条型号规格不一样而明确,一般规定电弧长短平稳不会改变,酸碱性焊条一般为3~4mm,偏碱焊条一般为2~2mm为宜?/span> </p> <p> <span style="font-family:SimSun;font-size:16px;">8、焊接视?依据两焊件的薄厚明确,焊接视角有两个层面,一是焊条与焊接正确方向的夹角为60~75°;二是焊条与焊接上下夹角有二种状况,当焊件薄厚相同时,焊条与焊件夹角均?5°;当焊件薄厚不一时,焊条与偏厚焊件一侧夹角应超过焊条与较薄焊件一侧夹角?/span> </p> <p> <span style="font-family:SimSun;font-size:16px;">9、收?每条焊缝焊到结尾,应将弧坑铺满后,往焊接方位反过来的方位带弧,使弧坑甩在焊缝里面,防止弧坑咬肉。焊接完钢架结构后,应选用氧割摘除弧板,并刃磨整平,不能用锤击毁?/span> </p> <p> <span style="font-family:SimSun;font-size:16px;">10、清?成条焊缝焊完后消除炉渣,经电焊工自查(包含外型及焊缝规格等)确实没有难题后就可以?/span> </p> <p><div>上一?<a href="203.html">贵州钢结构的三大链接方法</a></div> <div>下一?<a
