(4)焊接操作及配合人員按規(guī)定穿戴勞動(dòng)防護(hù)用品，并采取防止觸電、高空墜落、火災(zāi)等安全問(wèn)題的措施。 </p> <p> (5)戶(hù)外使用的焊機(jī)，應(yīng)設(shè)有防雨、防潮機(jī)棚，并應(yīng)裝設(shè)相應(yīng)的消防器材。 </p> <p> (6)上、下焊件要拿穩(wěn)，雙手配套絕緣無(wú)塵隔熱套應(yīng)與電極保持距離，裸露手指不能置于兩待焊焊件之間，以免灼傷。 </p> <p> (7)工作結(jié)束后，關(guān)閉加熱系統(tǒng)、氣體保護(hù)系統(tǒng)、真空系統(tǒng)、加壓系統(tǒng)，再關(guān)閉總電源。 </p> <p> <br />

擴(kuò)散焊是兩緊密貼合的焊件在真空或保護(hù)氣氛中，經(jīng)過(guò)一定溫度和壓力的保持，使接觸面的原子相互擴(kuò)散完成焊接的一種壓焊方法。這種焊接方法是在完全沒(méi)有液相或者*有極小量的過(guò)渡液相的參加下，通過(guò)金屬間原子相互擴(kuò)散與金屬鍵結(jié)合來(lái)實(shí)現(xiàn)兩焊件的焊接，其接頭內(nèi)不殘留任何鑄態(tài)結(jié)構(gòu)，且因?yàn)闆](méi)有引入任何其它元素，故其接頭成份和結(jié)構(gòu)與基體均勻一致，原始界面完全消失，兩焊件**終變成一個(gè)。這樣來(lái)實(shí)現(xiàn)我們所需要的結(jié)構(gòu)形狀。 </p><p> 鎳合金的擴(kuò)散焊 </p> <p> <p> 鎳合金具有優(yōu)良的耐高溫、耐腐蝕及耐磨損等性能，其熔焊時(shí)焊接性差，接頭韌性遠(yuǎn)低于母材，因此較多地應(yīng)用擴(kuò)散焊實(shí)現(xiàn)連接。 </p> <p> 鎳合金表面含有Ti和A1的氧化膜，比較穩(wěn)定，須仔細(xì)地進(jìn)行焊接表面準(zhǔn)備；在焊接過(guò)程中，嚴(yán)格控制氣氛，防止表面污染，通常還需要純鎳或鎳合金作中間層。鎳合金擴(kuò)散焊接的參數(shù)：加熱溫度1093～1204℃，保溫時(shí)間10～120min，壓力2.5～15MPa，真空度1.33×10-2Pa以上。創(chuàng)闊金屬制作擴(kuò)散焊接的技術(shù)已成熟，并能根據(jù)您的需要設(shè)計(jì)定制。歡迎咨詢(xún)。
