其癥狀是出現(xiàn)兩眼高度羞明、流淚、異物感、刺痛、眼瞼***、痙攣、并伴有***和視物模糊。焊接煙塵的危害焊接過程中會產(chǎn)生大量的金屬焊接粉塵，焊接產(chǎn)生的金屬粉直徑很小，較容易吸肺部，因直徑很小很難排出體外，故發(fā)生病變。焊接電流強度越大粉塵濃度越高，安徽H13焊絲。在焊接粉塵濃度較大的情況下，又沒有相應(yīng)的排塵措施時，長期接觸焊接粉塵能引起焊工塵肺、錳中毒和金屬熱等職業(yè)疾病。生殖毒性，近10年來國內(nèi)外開展了一些關(guān)于電焊作業(yè)生殖毒性的研究，主要涉及男工**質(zhì)量、女工生殖結(jié)局及損害機制。研究表明：電焊女工月經(jīng)的經(jīng)量增加、周期縮短、經(jīng)期延長、白帶增加，自然流產(chǎn)、早產(chǎn)、痛經(jīng)、均較對照組高，安徽H13焊絲。錳中毒男工**外觀呈均勻灰白色，PH值正常，平均液化時間比對照組延長。檢驗結(jié)果證明，錳中毒男工平均一次**量、精子總數(shù)、精子存活率及活動精子率均比對照組下降，錳中毒男工精子畸形率明顯高于對照組，安徽H13焊絲。認為金屬錳能夠影響男工生精系統(tǒng)，對精子的發(fā)育有直接毒作用，并能殺傷精子，從而引起男性**質(zhì)量的改變。國外也有報道電焊作業(yè)工人性***分泌改變，精子質(zhì)量下降，但對子代的性別比例沒有影響有害氣體的危害在焊接電弧高溫和強烈紫外線的作用下。為了防止焊絲生銹,須對焊絲(除不銹鋼焊絲外)表面進行特殊處理。安徽H13焊絲</p><div

使水龍頭4出來的水淋在上層槽2a的前側(cè)板上并分別濺入上層槽2a和連通槽2c，從而實現(xiàn)冷卻水的循環(huán)利用。水龍頭4在焊條進入上層槽2a的前方位置處進行噴淋冷卻水，提前對焊條進行預(yù)冷卻，同時在焊條進入上層槽2a后再次進行噴淋冷卻水，能有效防止焊條驟冷變形。比較好是，上層槽2a的前壁頂部設(shè)置有高于焊條過孔2b的溢水缺口2d，上層槽2a的冷卻水還能經(jīng)溢水缺口2d流入連通槽2c。另外，連通槽2c的橫截面呈三角形，以騰出空間使焊條從連通槽2c的上方通過。自動切斷機構(gòu)c，主要由工作臺12、安裝架13、立塊14、焊條導(dǎo)向管15、“門”形安裝架16、豎直氣缸6、焊條切斷刀7、螺栓8、上導(dǎo)向膠輪9和下導(dǎo)向膠輪10、限位柱11組成。工作臺12上安裝有上導(dǎo)向膠輪9和下導(dǎo)向膠輪10。上導(dǎo)向膠輪9和下導(dǎo)向膠輪10的中部分別設(shè)置有環(huán)向缺槽，且兩個環(huán)向凹槽正好圍成供橫截面為等邊三角形的焊條通過的通道，上導(dǎo)向膠輪9和下導(dǎo)向膠輪10轉(zhuǎn)動的同時，帶動焊條向后移動。在通道的正前方設(shè)置有左、右兩根限位柱11，供焊條從中穿過，左、右限位柱11通過“l(fā)”形板安裝到工作臺12上。工作臺12的后壁上安裝有安裝架13，安裝架13呈“7”字形并朝向后方。安裝架13的這種安裝方式，是為了讓切斷后的焊條能自動下落。安徽H13焊絲加入穩(wěn)弧劑使電弧穩(wěn)定，熔滴過渡均勻。</p><div

手工鎢極氬弧工藝特點工作原理鎢極氬弧焊是采用鎢棒作為電極，利用氬氣作為保護氣體進行焊接的一種氣體保護焊方法。通過鎢極與工件之間產(chǎn)生電弧，利用從焊噴嘴中噴出的氬氣流在電弧區(qū)形成嚴(yán)密封閉的氣層，使電極和金屬熔池與空氣隔離，以防止空氣的侵入。同時利用電弧熱來熔化基本金屬和填充焊絲形成熔池。液態(tài)金屬熔池凝固后形成焊縫。由于氬氣是一種惰性氣體，不與金屬起化學(xué)反應(yīng)，所以能充分保護金屬熔池不被氧化。同時氬氣在高溫時不溶于液態(tài)金屬中，所以焊縫不易生成氣孔。因此，氬氣的保護作用是有效和可靠的，可以獲得較高質(zhì)量的焊縫。焊接時鎢極不熔化，所以鎢極氬弧焊又稱為非熔化極氬弧焊。根據(jù)所采用的電源種類，鎢極氬弧焊又分為直流、交流和脈沖三種。焊不銹鋼用什么焊條？不銹鋼怎么焊接？焊接技術(shù)焊接是被焊工件的材質(zhì)（同種或異種），通過加熱或加壓或兩者并用，并且用或不用填充材料，使工件的材質(zhì)達到原子間的結(jié)合而形成長久性連接的工藝過程。那么不銹鋼焊接要點與注意事項有哪些要點呢？焊不銹鋼用什么焊條不銹鋼焊條可分為鉻不銹鋼焊條和鉻鎳不銹鋼焊條，這兩類焊條中凡符合國標(biāo)的，均按國標(biāo)GB/T983-2012規(guī)定考核。鉻不銹鋼具有一定的耐蝕。</p><p> 對電焊鉗的要求是：在任何斜度都能夾緊焊條；具有可靠的絕緣和良好的隔熱性能；電纜的橡膠包皮應(yīng)伸入到鉗柄內(nèi)部，使導(dǎo)體不外露，起到屏護作用；輕便、易于操作。電焊鉗的規(guī)格和主要技術(shù)數(shù)據(jù)見表3—5。表3—5電焊鉗的規(guī)格和主要技術(shù)數(shù)據(jù)規(guī)格(A)額定值適用焊條直徑(mm)耐電壓性能(V／min)能連接的比較大電纜截面(mm2)負載持續(xù)率(％)工作電壓(V)工作電流(A)～32300～26160～100035(二)焊接電纜焊條電弧焊在工作中除焊接設(shè)備外，還必須有焊接電纜。焊接電纜應(yīng)采用橡皮絕緣多股軟電纜，根據(jù)焊機的容量，選取適當(dāng)?shù)碾娎|截面，選取時可參考表3—6。如果焊機距焊接工作點較遠，需要較長電纜時，應(yīng)當(dāng)加大電纜截面積使在焊接電纜上的電壓降不超過4V，以保證引弧容易及電弧燃燒穩(wěn)定。不允許用扁鐵搭接或其它辦法來代替連接焊接的電纜，以免因接觸不良而使回路上的壓降過大，造成引弧困難和焊接電弧的不穩(wěn)定。表3—6焊接電纜選用表比較大焊接電流(A)0焊接電纜截面積(mm2)25507095焊機和焊接手柄與焊接電纜的接頭必須擰緊，表面應(yīng)保持清潔，以保證其良好的導(dǎo)電性能。不良的接觸會損耗電能，還會導(dǎo)致焊機過熱將接線板燒毀或使電焊鉗過熱而無法工作。。按照“先進先出”的原則發(fā)放焊絲，盡量減少產(chǎn)品庫存時間。</p><div

后者只預(yù)熱焊件邊緣較厚的部分。電源可采用直流正接，也可以采用交流。用交流電源焊接時，鋅的蒸發(fā)量較小。焊接參數(shù)宜采用較大的焊接電流和較快的焊接速度。厚16～20mm黃銅板的焊接參數(shù)為：焊接電流260～300A，鎢極直徑5mm，焊絲直徑～，噴嘴孔徑14～16mm，氬氣流量20～25L/min。為了減少鋅的蒸發(fā)，操作時可將填充焊絲與焊件'短接'，在填充焊絲上引弧和保持電弧，盡可能避免電弧直接作用到母材上，母材主要靠熔池金屬的傳熱來加熱熔化。焊接時，應(yīng)盡可能進行單層焊，板厚小于5mm的接頭，比較好能一次焊完。焊后焊件應(yīng)加熱到300～400℃進行退火處理，消除焊接應(yīng)力，以防止黃銅構(gòu)件在使用時破裂。4．黃銅碳弧焊黃銅碳弧焊時，根據(jù)母材的成分選用絲221、絲222、絲224等焊絲，也可用自制的黃銅焊絲施焊。焊接可以采用氣劑301等作熔劑。焊接應(yīng)短弧操作，以減少鋅的蒸發(fā)和燒損。?用薄鋼帶卷成圓形或異形鋼管，內(nèi)填一定成分的藥粉，經(jīng)拉制成的有縫藥芯焊絲。江蘇模具焊絲工廠</p><p
