Description

一种薄板船体结构的焊接方法 技术领域
本发明涉及船舶加工制造技术领域，尤其涉及一种薄板船体结构的焊接方法。
背景技术
船体建造时，在片体上安装球扁钢(即板材)等结构都是需要双面焊的，现阶段全部都是先焊接完结构某一侧的焊缝之后马上就焊接另一侧的焊缝。
对于单个结构而言，焊接完一侧的焊缝之后马上就去焊接另一侧的情况不利于结构的焊接变形的过程控制，容易导致最终冷却之后结构出现较大的变形。且由于结构的焊接过程，全凭现场施工人员的经验，没有统一的工艺文件规定，往往使得结构的变形情况处于不可控状态，无法预知。很多情况下需要后续工序对偏差大的位置进行开刀调整，浪费较多的人力物力。在薄板船体结构建造时，如果大面积的火攻调整会导致船体钢材的质量由于高温而产生变化，进而影响船体结构的质量。
在那些需要大量安装结构的部件或者分段，当局部的变形集中产生作用时，对船体结构内部受力的影响非常大，有很大的不利影响，可能会导致大面积开刀校正或者换板调整等，给船体结构建造质量、船舶生产成本控制以及船舶建造企业带来不良影响。
发明内容
本发明的目的在于提出一种薄板船体结构的焊接方法，能够解决现有技术中焊接造成的局部变形较大，导致船体大面积开刀矫正或者换板调整的问题。
为达此目的，本发明采用以下技术方案：
提供一种薄板船体结构的焊接方法，将多个板材吊装至片体的设定位置，先焊接每个所述板材与所述片体的同一侧的焊缝，再焊接每个所述板材与所述片体另一侧的焊缝。
作为优选，在吊装前先对每个所述板材用于连接所述片体的一端开设坡口，所述板材具有第一侧面和第二侧面，所述坡口包括开设在所述第一侧面的第一坡口和开设在所述第二侧面的第二坡口。
作为优选，所述第一坡口和所述第二坡口的倾斜角度相等，且两者之间具有钝边，所述钝边的宽度小于所述板材厚度的1/4。
作为优选，在所述板材与所述片体焊接前，在所述板材背离焊接的一侧设置防止所述板材焊接变形的防变形工装，当其中一侧焊接结束后，经过时间t1，拆除所述防变形工装并将所述防变形工装移动至已焊接的一侧。
作为优选，所述防变形工装包括工装基板和固定在所述工装基板远离所述片体的一侧的靠板；所述靠板与所述板材的侧面选择性抵接，所述工装基板靠近所述片体的一侧设置电磁组件，用于选择性吸附在所述片体上。
作为优选，所述片体未焊接处设置有多个压块。
作为优选，所述片体四周设置有卡码用以限定所述片体位置。
卡码还可以用于防止片体焊接时发生翘边情况，在一定程度上防止片体变形。
作为优选，所述卡码与地面可拆卸连接，且所述卡码高度可调节，用以配合不同厚度的片体使用。
作为优选，所述工装基板为整板结构，且所述工装基板的长度与所述板材的长度相同。
作为优选，所述电磁组件沿工装基板的长度方向间隔设置，且相邻电磁组 件之间的距离不大于50mm。
作为优选，所述压块质量为30～60kg。
作为优选，所述压块质量为50kg。

本发明中通过将每个板材与片体的同一侧先进行焊接，当所有板材同一侧均焊接完成后，再返回第一个焊接板材处，对板材另一侧进行焊接，逐个将所述板材同一侧焊接完成。该种方法能够使两侧焊接变形相互抵消，使得焊接后的片体安装能够更好的保证安装精度要求。

具体实施方式
为了使本领域技术人员更好地理解本发明的技术方案，下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。
本实施例中提供了一种薄板船体结构的焊接方法，将与多个板材1吊装至片体2的设定位置，先焊接每个板材1与片体2的同一侧的焊缝，再焊接每个板材1与片体2另一侧的焊缝。
其中，在吊装前先对每个所述板材1用于连接所述片体2的一端开设坡口，所述板材1具有第一侧面11和第二侧面12，所述坡口包括开设在所述第一侧面11的第一坡口111和开设在所述第二侧面12的第二坡口121。如图1所示，本实施例中，焊接时，先将焊接第一坡口111处，再焊接第二坡口121处。第一坡口111和所述第二坡口121的倾斜角度相等，且两者之间具有钝边，所述钝边的宽度小于所述板材1厚度的1/4。
需要说明的是，焊接每个板材1的另一侧焊缝时，需要从焊接时第一个焊接的板材1处焊接，这样能够保证第一个焊接的板材1焊接处热量完全散去，使得冷却后的结构不会出现较大的变形，不会影响片体2后续安装使用。
如图2所示，本实施例中焊接时先焊接左侧(通过箭头指向能够明确的获知)，再焊接右侧。
本实施例中在所述板材1与所述片体2焊接前，在所述板材1背离焊接的一侧设置防止所述板材1焊接变形的防变形工装，当其中一侧焊接结束后，经过时间t1，拆除所述防变形工装并将所述防变形工装移动至已焊接的一侧。如图3所示，所述防变形工装包括工装基板31和固定在所述工装基板31远离所述片体2的一侧的靠板32；所述靠板32与所述板材1的侧面选择性抵接，所述工装基板31靠近所述片体2的一侧设置电磁组件33，用于选择性吸附在所述片体2上。
工装基板31可以为整板结构，其长度与板材1的长度一致，而电磁组件33沿工装基板31的长度方向间隔设置，间隔距离不大于50mm；靠板32也可以为整板结构，或者间隔设置的多个结构；电磁组件33还可以是磁铁。
该种焊接方法，能够防止船体机构内部受力影响较大而导致大面积开刀矫正或者换板调整的问题，进而有效的提高了焊接合格率，且避免材料浪费的问 题。
由于板材1与片体2焊接时，片体2受热会出现鼓起的问题，为了能够使下一个板材1正常焊接，本实施例中所述片体2未焊接处设置有多个压块。其中压块可为不锈钢块或者铸铁块，其中压块的尺寸一般限定宽为400mm，长为500mm，而压块的厚度为25～30mm，将压块尺寸限定为上述参数，能够使焊接工人方便将压块转移，不会造成焊接过程中需要耗费大量人力去转移压块的问题。同时压块为矩形块，能够使压块的底面与片体2较好的接触，使片体2的鼓起程度进一步减小。为了便于焊接工人能够实现单人或者双人搬运的目的，本实施例中所述压块质量为30～60kg；具体的，所述压块质量为50kg。
本实施例中通过对每个板材1同一侧先焊接，然后再对每个板材1的另一侧再次进行焊接，该种焊接方式与压块结合，能够有效的减少焊接处变形量，提高焊接合格率。
片体2焊接时，需要先对片体2进行限位，为此，本实施例中所述片体2四周设置有卡码用以限定所述片体2位置。当然卡码还可以是装夹机构或者装压机构，以能够实现对片体2装卡定位不会在焊接出现移动为准。其中卡码可以与地面可拆卸连接，且卡码高度能够根据不同厚度的片体进行调节，以方便不同厚度的片体2使用。
本实施例中片体2厚度为4～5mm；焊接温度为180～200℃。
为了保证焊接质量，本实施例在焊接之前还还包括：将待焊接板材1和片体2的待焊接处进行表面局部处理。将待焊接板材1与片体2进行表面局部处理的目的是防止焊接处铁锈、水分、油污对焊接产生不良影响，防止焊接出现咬边等质量问题。同时，焊接时使用普通焊枪，而焊接则采用CO2半自动焊。本实施例中采用CO2半自动焊焊接，节省经济成本。
注意，以上显示和描述了本发明的基本原理和主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施方式的限制，上述实施方式和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内，本发明的要求保护范围由所附的权利要求书及其等效物界定。
