停车棚钢构件焊接工艺与焊接连接的优点
来源:http://www.sdcscp.com/ 发布时间:2022-08-04
膜结构停车棚作为一种环保新型建筑,保证其稳定牢固的主要部分就是钢架结构,而使钢结构各部分之间稳固连接的就是钢构件,对于钢构件来说连接方式有多种,常用的一种连接方式就是焊接,这里为大家整理了车棚钢构件焊接工艺与焊接连接的优点,以供大家参考。
As a new type of environment-friendly building, the main part to ensure its stability and firmness is the steel frame structure, and the steel members are the ones that firmly connect the various parts of the steel structure. For steel members, there are many ways to connect, and one of the commonly used ways to connect is welding. Here, we have sorted out the advantages of the welding process and welding connection of the steel members of the shed for your reference.
膜结构车棚钢构件焊接工艺
Welding technology of steel components of membrane structure shed
手工焊接应采用多层多道、小电流的焊接方法。
Manual welding shall adopt multi-layer, multi-channel and low current welding method.

焊接连接的优点
Advantages of welded connection
(1)不需打孔,省工省时;
(1) There is no need to punch holes, which saves labor and time;
(2)任何形状的构件可直接连接,连接构造方便;
(2) Components of any shape can be directly connected, and the connection structure is convenient;
(3)气密性、水密性好,结构刚度较大,整体性较好。
(3) It has good air tightness and water tightness, large structural stiffness and good integrity.
通过以上内容可以看出,膜结构车棚钢构件焊接工艺主要还是以手工电弧焊为主,而这种焊接工艺对操作人员的技术要求较高,在后续的防腐工艺中也需要焊缝满足相当高的要求。更多事项您可以来网站http://www.sdcscp.com咨询吧。
From the above content, it can be seen that the welding process of steel components of membrane structure shed is mainly manual arc welding, and this welding process has high technical requirements for operators. In the subsequent anti-corrosion process, the welds also need to meet quite high requirements. You can visit the website for more information http://www.sdcscp.com Consult.
