WELDOX系列板材性能特點(diǎn)1.1 化學(xué)成分（指標(biāo)由廠家提供，見表1）1.2 焊接性能WELDOX高強(qiáng)度結(jié)構(gòu)鋼板的合金含量低，碳當(dāng)量低，從而可用任何普通的電弧焊方法，就可將其焊在普通結(jié)構(gòu)鋼板上。在焊接WELDOX板時(shí)，其目標(biāo)是：在焊接接頭處獲得適當(dāng)?shù)膹?qiáng)度和良好的韌性。根據(jù)國(guó)際焊接學(xué)會(huì)推薦的碳當(dāng)量公式CE(IIW)=C+Mn/6+（Cu+Ni）/15+（Cr+Mo+V）/5(質(zhì)量分?jǐn)?shù))(%)隨著碳當(dāng)量的增加,鋼材的焊接性回變差,當(dāng)CE值大于0.4%～0.6%時(shí),冷裂紋的敏感性將增大,焊接時(shí)需采取預(yù)熱、后熱等系列工藝措施.當(dāng)焊接結(jié)構(gòu)鋼時(shí)，盡量減少冷卻裂紋出現(xiàn)（氫裂或延期裂紋）至關(guān)重要。產(chǎn)生裂紋出現(xiàn)的主要原因是在有應(yīng)力出現(xiàn)的焊口處有氫氣存在。1.3 機(jī)械性能值（指標(biāo)由廠家提供，見表2）1.4 焊縫強(qiáng)韌性匹配工程機(jī)械的工作工況大多需要承受動(dòng)載荷及重載荷，對(duì)焊縫的要求除強(qiáng)度指標(biāo)外，還要求有較高的韌性。對(duì)于焊縫強(qiáng)度的選擇問題，長(zhǎng)期以來其高強(qiáng)鋼的焊接大多采用“等強(qiáng)度匹配”，但對(duì)與諸如WELDOX系列鋼板，σb≥800MPa高強(qiáng)鋼，除考慮強(qiáng)度外，還必須考慮焊接區(qū)的韌性和裂紋敏感性。就焊縫金屬而言，強(qiáng)度越高，可達(dá)到的韌性水平往往越低，甚至低于母材的韌性水平。因此，在特殊情況下,對(duì)焊縫金屬?gòu)?qiáng)度要求可低于母材,或剛度很大的焊接結(jié)構(gòu),為了減少焊接冷裂紋傾向,可選擇比母材強(qiáng)度低一些的焊接材料.2 焊接工藝方法2.1預(yù)熱預(yù)熱對(duì)平頭焊縫和根部焊道最為重要。焊接過程中和焊接后的溫度越高，則氫越容易逸出；鋼板越厚，預(yù)熱的必要性越大，以補(bǔ)償厚板更快的冷卻速度，而且厚板的碳當(dāng)量值更高；環(huán)境溫度低于5℃、周圍濕度偏高時(shí)更應(yīng)預(yù)熱；對(duì)被剛性固定的工件焊接時(shí)，預(yù)熱也是必須的；對(duì)不同鋼種的鋼焊接在一起時(shí)或焊接材料的碳當(dāng)量比母材高，預(yù)熱溫度由碳當(dāng)量最高的母材或焊接材料決定。表3列出了不同板厚的材料推薦的預(yù)熱溫度。說明∶推薦的預(yù)熱溫度基于如下條件：接接金屬的氫含量不超過5ml/100g；（1）預(yù)熱溫度的測(cè)量點(diǎn)為距焊縫75mm的點(diǎn)域，如圖1所示。（2）鋼板總厚度Σt= t1+t2+t3，其中ti為距焊接金屬75mm內(nèi)的平均厚度，如右圖所示。（3）格控制焊接線能量 大約為17KJ/cm。若焊料碳當(dāng)量高于鋼板，焊料的碳當(dāng)量決定預(yù)熱溫度。在此焊接極限熱量以下的焊接可以在熱影響區(qū)獲得滿意的韌性、強(qiáng)度和硬度(注：輸入熱量按公式可進(jìn)行計(jì)算,其中η為焊弧效率因素，當(dāng)用手工電弧焊時(shí)η=0.8-0.9，氣焊（MIG/MAG）時(shí)η=0.85，埋弧焊時(shí)η=1.0，鎢極惰性氣體保護(hù)焊時(shí)η=0.65；V為焊接速度（mm/min）。)；（4）焊接層間溫度控制推薦下表的溫度值；當(dāng)板厚大于8mm時(shí)，必須分多層焊接，第一層用ER49-1進(jìn)行打底焊，第二層焊滿，焊接層間溫度控制在150～175℃之間，焊接速度30～36cm/min，電流220～260A，電壓22～28V，送絲速度為7～9m/min。焊接層間溫度控制的溫度值表如表4：2.2預(yù)處理所有焊縫焊前必須保證焊道干燥、清潔，除掉其中表面的油、水、銹和防銹漆，預(yù)熱后必須用鋼刷清理焊縫區(qū)域以清除積碳。焊絲.坡口及坡口周圍10～20mm范圍內(nèi)必須清理干凈，不得有影響焊接質(zhì)量的鐵銹.油污.水和涂料等異物。對(duì)于重要焊縫，在焊縫兩端應(yīng)設(shè)置尺寸合適的引弧板和引出板。在不能使用引弧板和引出板時(shí)，應(yīng)注意防止在引弧處和收弧處產(chǎn)生焊接缺陷。2.3 焊后熱處理WELDOX只有在設(shè)計(jì)規(guī)則有特殊要求時(shí)方應(yīng)進(jìn)行焊后熱處理。避免裂紋出現(xiàn)的辦法有：焊前預(yù)熱母體材料；確保焊接面的清潔與干燥；選擇含氫小的焊料；通過良好的焊接順序與工作的合理匹配減少收縮內(nèi)應(yīng)力新手上路成長(zhǎng)任務(wù)編輯入門編輯規(guī)則本人編輯我有疑問內(nèi)容質(zhì)疑在線客服官方貼吧意見反饋投訴建議舉報(bào)不良信息未通過詞條申訴投訴侵權(quán)信息封禁查詢與解封?2025?Baidu?使用百度前必讀?|?百科協(xié)議?|?隱私政策?|?百度百科合作平臺(tái)?|?京ICP證030173號(hào)?京公網(wǎng)安備11000002000001號(hào)window.PAGE_DATA= {"lemmaId":2680951,"lemmaTitle":"","lemmaDesc":"瑞典超高強(qiáng)度鋼板","lemmaType":0,"uid":455794624,"uname":"蘇州正廣信金屬","createTime":1323231477,"updateTime":1658737694,"isDefault":0,"isDeleted":0,"rank":1,"extData":{"audit_comment_category":2,"isBaikeV6":1,"isFrontV6":1,"isSapp":0,"isWaitForPersonal":false,"kpdClassify":[{"id":337568,"name":"電子產(chǎn)品"},{"id":337502,"name":"工業(yè)產(chǎn)品"}],"lemmaId":7031008,"lemma_id":7031008,"newEditor":1,"pass_count":9,"subLemmaId":7176867,"updateTime":1658737694,"wapEdit":2},"extFlag":0,"versionId":431007261,"versionUid":4130194414,"versionUname":"豬小屁665","versionCreateTime":1658733588,"catalog":[{"level":1,"title":"基本信息","index":"1","uuid":"gnx2npm8p1","height":28},{"level":1,"title":"規(guī)格","index":"2","uuid":"gnx2no4dgy","height":28}],"abstract":[],"modules":{"adManager":{"data":{"wapRelatedBusiness":1}},"discussion":{"showHelpEdit":1},"globalConfig":{"data":{"serviceAdLemmaCategory":[337597,337474]}},"paper":{"switch":false},"pinzhuan":{}},"card":{"type":243,"left":[{"key":"name","title":"中文名","isArray":false,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":""}]}]},{"key":"application","title":"應(yīng)用","isArray":false,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":"主要應(yīng)用是承重"}]}]}],"right":[{"key":"customDefault","title":"特點(diǎn)","isArray":false,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":"具有非常高的純度和硬度"}]}]},{"key":"definition","title":"定義","isArray":false,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":"瑞典超高強(qiáng)度鋼板"}]}]}]},"lemmaCnt":1,"tips":{"isPolyseme":0},"encodeLemmaId":"294b5d3c64b26d2ad4c9cd4d","versionUk":"1mvOCzu3mbRkXuGtAJd49A","description":"瑞典超高強(qiáng)度鋼板 WELDOX700/900/960/1100/1300其中WELDOX威達(dá) 1300 是全球第一種強(qiáng)度可達(dá)到 1300 Mpa 的結(jié)構(gòu)鋼板 W..."}window.__abbaidu_2020_subidgetf||(window.__abbaidu_2020_subidgetf=function(){return"01000000"}) weldox960瑞典超高強(qiáng)度鋼板 WELDOX700/900/960/1100/1300其中WELDOX威達(dá) 1300 是全球第一種強(qiáng)度可達(dá)到 1300 Mpa 的結(jié)構(gòu)鋼板 WELDOX威達(dá) 1300 的主要應(yīng)用是承重，如起重機(jī)，此外還可應(yīng)用于一些新的領(lǐng)域?；拘畔⒗?，在某些情況下，可使用 WELDOX威達(dá) 1300 替代鈦和鋁。 WELDOX威達(dá) 1300 采用優(yōu)化的生產(chǎn)工藝，具有出色的焊接性和可彎曲性。由于二次冶煉產(chǎn)生的獨(dú)特效果，這種鋼材還具有非常高的純度和硬度。 WELDOX威達(dá) 1300 厚度在 4 到 10 毫米之間，可采用所有傳統(tǒng)焊接方法進(jìn)行焊接。1.
